Explanation:

hydrogen fuel can be produced from methane or by electrolysis of water. as of 2020, the majority of hydrogen (∼95%) is produced from fossil fuels by steam reforming or partial oxidation of methane and coal gasification with only a small quantity by other routes such as biomass gasification or electrolysis of water.

Answers

Natural gas contains methane (CH[tex]4[/tex]), which is used to produce hydrogen by thermal processes like stem-methane reformation and partial oxidation.

In steam-methane reforming, which is the most common method to produce hydrogen, high temperature steam (700°C - 1000°C). The pressure required is 3-25 bar pressure, in the presence of a catalyst. Steam reforming is an endothermic process. Carbon monoxide and steam are reacted using catalyst to produce carbon dioxide and hydrogen.

Partial oxidation is an exothermic process. It is much faster than steam reforming. This method initially produces less hydrogen.

These processes are more preferred because the use of petroleum is low and the emissions is also low. Total greenhouse gases emission is cut.

(a.) a 0.7549g sample of the compound burns in o2(g) to produce 1.9061g of co2(g) and 0.3370g of h2o(g).

Answers

The individual mass of C, H and O in given sample are 0.5196 g, 0.0374 g and 0.1979 g respectively.

Moles of CO2 formed can be calculated as

= Mass of CO2 / Molar mass of CO2

= 1.9061 / 44 = 0.0433 moles

Calculation of no. of moles of carbon

Now, moles of C which is present in one mole of CO2 = 1 mole

Moles of C in 0.0433 moles of CO2 = 0.0433 moles

As we know that, molar mass of C = 12 g / mol

Mass of C in 0.7549 g of given sample can be calculated as

= 0.0433 × 12 =0.5196 g

Mass of H2O formed = 0.3370 g

Similarly, Molar Mass of H2O = 18 g / mol

Moles of H2O = 0.3370 / 18 = 0.0187 moles

Moles of H present in 1 mole of H2O = 2 moles

Moles of H present in 0.0187 mole of H2O = 2 × 0.0187 = 0.0374 moles

Molar mass of H = 1 g / mol

Mass of H contained in 0.7549 g of sample = 1 × 0.0374= 0.0374 g

Mass of O in 0.7549 g sample can be calculated as

= 0.7549 – [(Mass of C ) + (Mass of H) ]

= 0.7549 – [ (0.5196) + (0.0374) ]

= 0.1979 g

Thus, we calculated that the individual mass of C, H and O in given sample are 0.5196 g, 0.0374 g and 0.1979 g respectively.

STP -  STP or Standard Temperature and Pressure, refers to the nominal atmospheric conditions at sea level. 0 degrees Celsius and 1 atmosphere are the respective temperatures and pressures. The STP value is essential for physicists, chemists, engineers, pilots, and navigators in addition to other specialists.

In order to report on the qualities of matter, standard conditions for temperature (T) and pressure (P) relate to a certain temperature and pressure. STP values are frequently applied in gas experiments.

STP was previously defined as follows by the International Union of Pure and Applied Chemistry (IUPAC):

It is 0 degrees Celsius outside (273.15 degrees Kelvin or 32 degrees Fahrenheit)

One atmosphere (101.325 kilopascal or 760 Torr)

This usage of the term has been dropped. However, the definition of the volume (V) term normal cubic meter continues to be often employed under these circumstances. The IUPAC has used a stricter definition of STP since 1982:

Absolute pressure: 105 Pa or 100,000 pascals (1 bar, 14.5 pounds per square inch, 0.98692 atm).

Answers

a) The substances in A and B mix and the result is depicted in C is chemical change.

b) The substances in A and B mix and the result is depicted in D is chemical change.

c) Under a third set of conditions, the sample depicted in C changes to that in D is a kind of physical change.

d) When the change in part (c) occurs both the sample formed have same chemical properties.

In first case,

When the substances A and B mix and the result is depicted in C this implies that A and B react to give another substance C. Since C contain atoms of both A and B therefore, it have different property than A and B. So, it is a kind of chemical change.

In second case,

When the substances A and B mix and the result is depicted in D this implies that A and B react to give another substance D in different set of condition. Since D also contain atoms of both A and B therefore, it also have different property than A and B. So, it is a kind of chemical change.

In third case,

As we know that C and D both formed by the reaction between A and B in different set of conditions. So, we can say that C and D basically differ from each other in terms of state. So, C can be converted into D by either cooling or boiling. So, it is a kind of physical change.

In fourth case,

Since, we found that both C and D are differ in state of matter but they have same Chemical properties as both are formed of A and B. So, we can say that, C and D have same chemical properties but have different Physical properties.

Thus, we concluded that when A and B react to form C and in other case form D it is Chemical change. When C converted into D, it is physical change while both have same chemical properties.

recommended dose. Has this patient received an overdose?

Answers

The patient has not received an overdose because only 150 mg of the drug was given instead of 202.488mg which is the maximum recommended dose.

Calculation of drug dosage

The weight of the patient= 135lb

The weight of patient in Kg is calculated as follows,

1 kg = 2.2lb

Xkg = 135Ib

Xkg= 135/2.2

Xkg = 61.36kg

The maximum recommended dose for the drug = 3.3mg/kg

That is, if 3.3 mg = 1 kg

Xmg = 61.36kg

Xmg = 61.36 × 3.3 = 202.488mg

The number of teaspoon administered = 2 = 10ml each containing 75mg of the drug.

The patient received 75 mg ×2 = 150mg of drug.

a piece of copper metal is initially at 100.0°c. it is dropped into a coffee cup calorimeter containing 50.0 g of water at a temperature of 20.0°c. after stirring, the final temperature of both copper and water is 25.0°c. what is the mass of copper piece used?

Answers

The mass of copper piece use is 13.9 J/K

We are given:

• Initial temperature of copper, [tex]T_{Cu, i}[/tex] = 100°C

• Mass of water, [tex]m_{water}[/tex] = 50 g

• Initial temperature of water,[tex]T_w, i[/tex] = 20°C

• Final temperature, [tex]T_f[/tex] = 25°C

• Specific heat capacity of water, [tex]c_{water}[/tex]= 4.18 J/gK

From the given information, we need to determine the heat capacity of the copper ( [tex]C_{Cu}[/tex]).

The heat released by the copper can be calculated as:

[tex]Q_{Cu}=C_{Cu}(T_{f } - T_{Cu, i})[/tex]

While the heat absorbed by the water can be calculated as:

[tex]Q_{water}=m_{water}c_{water}(T_{f } - T_{w, i})[/tex]

we can assume that the heat released by the copper is just fully absorbed by the water. The sum of the two heats is zero.

[tex]Q_{Cu} + Q_{water } = 0[/tex]

[tex]C_{Cu}(T_f - T_{Cu, i}) + m_{water}c_{water}(T_f - T_{w,i} ) = 0[/tex]

Since we want to calculate the heat capacity of copper, we can rearrange the equation to obtain an equation for [tex]C_{Cu}[/tex].

[tex]C_{Cu}= \frac{ m_{water}c_{water}(T_f - T_{w,i} )} {(T_f - T_{Cu, i})}[/tex]

Since we are given the necessary information to solve the problem, we can just substitute the given values in the equation. Please note that the difference in temperatures in Kelvin is the same as the difference in temperatures in °C. So in this case, we can simply plug in the temperature values without changing them to Kelvin first.

[tex]C_{Cu}= \frac{ m_{water}c_{water}(T_f - T_{w,i} )} {(T_f - T_{Cu, i})} = \frac{(50g)(4.18J/gK)(25\textdegree C - 20\textdegree C)}{25\textdegree C-100\textdegree C}[/tex]

In simple summary form, the calvin cycle requires an input of __________ for every product that is formed and the output product is __________, which is used for glucose synthesis.

Answers

In simple summary form, the calvin cycle requires an input of 3 CO₂ for every product that is formed and the output product is a three-carbon molecule, which is used for glucose synthesis.

Calvin cycle is light-independent (dark) reactions or carbon reactions.

In photosynthesis (convert light energy into chemical energy), the carbon in carbon(IV) oxide is being reduced to form glucose.

The pigment chlorophyll absorbs one photon and loses one electron (it passed throw an electron transport chain) in the light-dependent reactions.

The enzyme RuBisCO takes carbon(IV) oxide in the light-independent reactions.

During Calvin cycle, three molecules of carbon dioxide (CO₂) are combined with hydrogen ions to form three carbon-molecules (see the picture).

Answers

Sunlight energy can be converted by photosynthesis into chemical energy in the form of carbohydrates, which can then be used by the body for cellular respiration. Humans employ oxygen and carbohydrates, the byproducts of photosynthesis, to create energy, water, and carbon dioxide. Human breath carbon dioxide is used by the plant to complete photosynthesis.

Green plants and certain other organisms convert light energy into chemical energy through a process called photosynthesis. Light energy is gathered and utilized during photosynthesis in green plants to change the water, carbon dioxide, and minerals into oxygen- and energy-rich organic molecules.

It is impossible to overstate the role that photosynthesis plays in sustaining life on Earth. There would soon be little food or other organic materials on Earth if photosynthesis stopped. The majority of life would vanish, and eventually, the atmosphere of Earth would contain almost no gaseous oxygen. Only chemosynthetic bacteria, which can use the chemical energy of specific inorganic substances and are not reliant on the conversion of light energy, would be able to survive in such an environment.

Answers

D

Explination: During condensation, a substance is changed from the gaseous to the liquid state of matter. Vaporization, which is more often referred to as "boiling," is the complementary process in which a chemical is converted from the liquid state of matter to a gaseous physical form.

Ions form the _____ number of an atom is changed

A proton
B neutron
C electron
D atomic number

Answers

Protons is the correct answer.

Ions form the proton number of an atom is changed. The correct option is A.

Thus, An atom will be neutrally charged if its protons and electrons are equal in number. An ion is created when an atom's protons and electrons are different numbers.

It is technically possible to make an ion if the number of protons varies but the number of electrons stays the same. The identity of the atom is determined by the amount of protons, not by the atom itself, which will change.

An isotope would be produced if the neutron count varied. An ion will also form if the number of electrons changes because this will cause a change in charge.

Thus, Ions form the proton number of an atom is changed. The correct option is A.
