Answer 1

1409.36ml

chemist wants to make 5,748 mL of a solution with a concentration of 2.55 M. How many liters of a 10.40 M solution should be used to make this solution

from the above statement, we have got

[tex]M_1[/tex]= 2.55 M.                    [tex]M_2[/tex]=10.40 M

[tex]V_1[/tex]=  5,748 mL                     [tex]V_2[/tex]=?

now, from the formula,

[tex]M_1V_1=M_2V_2[/tex], In this M is molarity and V is Volume

now put the values in the equation,

2.55×5748=10.40×[tex]v_2[/tex]

[tex]V_2[/tex] = 2.55×5748÷10.40

[tex]V_2[/tex]= 14,657.4÷10.40

[tex]V_2[/tex]=1409.36ml

.The number of moles of solute dissolved in one liter of solution is known as the molarity, which is the concentration of a solution. it's unit is mole per litre. it is temperature dependent concentration.

Which element, Oxygen (O) or Fluorine (F), has a smaller atomic radius?

O, because the attraction between protons and valence electrons is weaker.
F, because the attraction between protons and valence electrons is stronger.
F, because the attraction between protons and valence electrons is weaker.
O, because the attraction between protons and valence electrons is stronger.

Answers

Fluorine has a smaller ionic radius than oxygen, because the attraction between protons and valence electrons is stronger; option B

What is ionic radius?

Ionic radius is the radius of an ion of an element.

The ionic radius of ions of elements depends on the nuclear charge as well as the number of electrons in the outermost shell of of an ion of an element.

The nuclear charge is the charge on the nucleus as a result of the positively-charged proton present in the nucleus. The proton exerts an attractive force on the electrons, thus reducing the size of the ion if nuclear charge increases.

The ionic radius of metallic ions decrease from left to right across the period table as a result of the increase in the nuclear charge of the ions.

However, the ionic radius of metals increase on going down a group in the periodic table.

Similarly, the ionic radius of non-metallic ions decrease from left to right across the period table as a result of the increase in the nuclear charge of the ions.

The ionic radius of non-metals also increase on going down a group i the periodic table.

Therefore, the ionic radius of oxygen will be greater than that of fluorine because of a smaller nuclear charge.

Answers

The accurate responses are;

1) it has the configuration of of the noble gas in the same period

2) higher, gain, more

What is the electron configuration?

The electron configuration shows the arrangement of the atoms in an element. We know that in an element, the nucleus is at the core of the atom. The shells have energies increasing order with the shells that are close to the nucleus having the lowest energy and the energy of the shells tends to increase radially outwards from the nucleus.

Now let us try to look at sodium. We know that the formation of ions leads an element to attain the noble gas configuration. We can see that when sodium loses an electron, it closely resembles the noble gas neon.

The ionization energy is the energy that is required for the removal of one electron from the outermost shell of the atom. The complete statement therefore is; Ionization energies for nonmetals are higher than metals because they would rather gain  electrons than lose electrons, so it takes more energy.

What is the equation of the reaction?

We know that it is not possible to obtain the solutions to a problem of this sort unless we are able to obtain the balanced reaction equation. This is the only way that we are able to apply the stoichiometry solve the problem.

We have the balanced reaction equation as;

5Ca(OH)₂ + 3H₃PO₄ ---> Ca₅(PO₄)₃(OH) + 9H₂O.

Number of moles acid =  128 g /98.00 g/mol = 1.31 moles

Number of moles of calcium hydroxide = 113 g/ 74 g/mol = 1.59 moles

If 5 moles of calcium hydroxide reacts with 3 moles of acid

1.59 moles of calcium hydroxide reacts with 1.59 moles *  3 moles / 5 moles

= 0.954 moles

Hence  calcium hydroxide is the limiting reactant.

Now;

5 moles of  calcium hydroxide yields 1 mole of hydroxyapatite

1.59 moles  of  calcium hydroxide yields   1.59 moles  * 1 mole /5 moles

= 0.318 moles of hydroxyapatite

The density of a solution of sulfuric acid is 1.8022g/cc and it is 88.00 percent by mass. What is the volume of the solution ( in millimetre) do you need to supply 43.0g of sulfuric acid.

Answers

Considering the definition of percentage by mass, you need a volume of solution of 20.9965 mL to supply 43 g of sulfuric acid.

Definition of percentage by mass

The Percentage Composition is a measure of the amount of mass that an element occupies in a compound and indicates the percentage by mass of each element that is part of a compound.

The percentage by mass is calculated as the mass of the solute divided by the mass of the solution, the result of which is multiplied by 100 to give a percentage. This is:

percentage by mass= (mass of solute÷ mass of solution)× 100

Definition of density

Density is a quantity that allows to measure the amount of mass in a certain volume of a substance.

The expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

density= mass÷ volume

Volume of the solution needed

In this case, you know:

density of the solution of sulfuric acid= 1.8022 g/ccpercentage composition= 88 percent by massmass of the solution= 43 g

First, you calculate the mass of sulfuric acid considering the definition of percentage by mass:

88= (mass of solute÷ 43 g)× 100

Solving:

88÷ 100= mass of solute÷ 43 g

0.88=mass of solute÷ 43 g

0.88×43 g= mass of solute

37.84 g= mass of solute

Now, the volume is calculated taking into account the definition of density:

1.8022 g/cc= 37.84 g÷ volume

Solving

1.8022 g/cc× volume= 37.84 g

volume= 37.84 g÷ 1.8022 g/cc

volume= 20.9965 cc= 20.9965 mL (being 1 cc= 1 mL)

Finally, you need a volume of solution of 20.9965 mL to supply 43 g of sulfuric acid.

In a collision between two objects both objects experience forces of equal magnitude and in opposite directions. Such forces often cause one object to accelerate and gain momentum, and another to decelerate and lose momentum.

The kinetic energy of the whole system before the collision equals the kinetic energy of the whole system after the collision. If all the kinetic energy is not conserved, the collision is called an inelastic collision. For collisions between two objects, momentum is conserved. The initial momentum is non-zero, so the final momentum is non-zero. Both objects cannot be at rest. It is possible that one of the objects remained after the collision.

When two cars collide your car pushes the other car. According to Newton's 3rd law, this car is pushing your car in the opposite direction with the same force. This power slows you down. In a collision, objects always encounter momentum and momentum changes. In a collision, the momentum received by an object equals the change in velocity. The velocity change of the two objects involved in the collision is always the same.

A 8.07 g sample of HCN is found to contain 0.299 g of H and 4.18 g of N. Find the mass of carbon in a sample of HCN with a mass of 3.28 g .

Answers

The mass of carbon in a sample of the compound is 1.46 g

What is the percent mass of Carbon in the sample of he compound?

The percent mass of Carbon in the sample of he compound is calculated as follows:

Percent mass = mass of carbo/mass of sample * 10%

Mass of sample of compound = 8.07 g

Mass of H = 0.299 g

Mass of N = 4.18 g

mass of carbon = 8.07 g - 0.299 g - 4.18 g

Mass of carbon = 3.591 g

Percent mass of carbon = 3.591/8.07 * 100%

Percent mass of carbon = 44.5 %

Therefore, mass of carbon in a sample of the compound with a mass of 3.28 g  = 3.28 g * 44.5%

mass of carbon in a sample of the compound = 1.46 g

When 53 J of heat is added to 15 g of a liquid, its temperature rises from 10.7 °C to
13.0°C.

What is the heat capacity of the liquid?

Answers

The heat capacity of liquid is  1.53 J/ g°C

Heat capacity measures the energy required to raise temperature of a unit mass of a substance by a unit degree

Formula used:

          Q = m × c ×  ΔT

               = m × c × ( T₂ - T₁ )

where,

Q = Amount of heat gained or lost  = 53 J

m = mass of liquid = 15 g

c = specific heat of liquid = ?

ΔT = change in temperature

T₁ = initial temperature = 10.7 °C

T₂ = final temperature = 13 °C

Substituting the values in the formula

        53 J = 15 g × c × ( 13 - 10.7) °C

         53 J = 15 g × c × 2.3 °C

             c = 53/ ( 15 × 2.3 )

                = 1.53 J/ g°C

Thus we can conclude that the heat capacity of liquid is  1.53 J/ g°C
