plz do not scam ​

Answers

Answer 1
The formula for unionized ammonia is NH3. The ionized form of ammonium has the formula NH4+. Water pH is the most important element in determining the amount of ammonia or ammonium in water. Temperature and ionic strength have an impact on ammonia activity.

The gas in an aerosol can is at a pressure of 3.10 atm at 25 degrees Celsius. Directions on the can warn the user not to keep the can in a place above 52 degrees Celsius. What would the gas pressure in the can be at 52 degrees Celsius

Answers

Answer:

[tex]\boxed {\boxed {\sf 6.4 \ atm}}[/tex]

Explanation:

We are asked to find the pressure of a gas in a can given a change in temperature. We will use Gay-Lussac's Law, which states the pressure of a gas is directly proportional to the temperature. The formula for this law is:

[tex]\frac {P_1}{T_1}= \frac {P_2}{T_2}[/tex]

Initially, the gas in the aerosol can has a pressure of 3.10 atmospheres at a temperature of 25 degrees Celsius.

[tex]\frac { 3.10 \ atm}{25 \textdegree C}=\frac{P_2}{T_2}[/tex]

The temperature is increased to 52 degrees Celsius, but the pressure is unknown.

[tex]\frac { 3.10 \ atm}{25 \textdegree C}=\frac{P_2}{52 \textdegree C}[/tex]

We are solving for the new pressure, so we must isolate the variable [tex]P_2[/tex]. It is being divided by 52 degrees Celsius. The inverse operation of division is multiplication, so we multiply both sides of the equation by 52 °C.

[tex]52 \textdegree C *\frac { 3.10 \ atm}{25 \textdegree C}=\frac{P_2}{52 \textdegree C} * 52 \textdegree C[/tex]

[tex]52 \textdegree C *\frac { 3.10 \ atm}{25 \textdegree C}=P_2[/tex]

The units of degrees Celsius cancel.

[tex]52 *\frac { 3.10 \ atm}{25}=P_2[/tex]

[tex]52 *0.124 \ atm = P_2[/tex]

[tex]6.448 \ atm = P_2[/tex]

The original values of pressure and temperature have 2 and 3 significant figures. Our answer must be rounded to the least number of sig figs, which is 2. For the number we calculated, that is the tenths place. The 4 in the hundredth place tells us to leave the 4 in the tenths place.

[tex]6.4 \ atm \approx P_2[/tex]

The gas pressure in the can at 52 degrees Celsius is approximately 6.4 atmospheres.

how many g/mL are in 12cg/L

Answers

Answer:

0.00012 g/ml

Explanation:

g are 100 x cg, and litres are 1000 x ml, so the number 12 needs to be divided by 100 x 1000 = 100,000 in order to get the correct result.

But you can also work through and figure it out logically.

1 cg = 0.01 g, so 12 cg = 0.12 g

So you have 0.12 g in 1 litre, which is 0.12 g in 1000 ml.

This means that in 1 ml you have 0.12/1000 = 0.00012 g.

Los elementos que forman aniones con carga -1 y una capa externa estable de ocho electrones pertenecen al grupo de los:

Answers

Los elementos que forman aniones con carga -1 y una capa externa estable de ocho electrones pertenecen al grupo de los: halógenos.

Para alcanzar la estabilidad, los átomos siguen la regla del octeto: ganan, pierden o comparten electrones para tener 8 electrones en su capa externa (capa de valencia).

Los elementos del Grupo 17 de la Tabla Periódica, conocidos como halógenos, tienen 7 electrones en su capa de valencia. Así, tienden a ganar 1 electrón para completar su octeto. Como los electrones tienen carga negativa, al ganar 1 electrón los aniones quedan con una carga de -1.

Which particle is most likely present in the nucleus of the atom?
O Only particle A
O Only particle C
O Both particles A and B
Both particles B and C

Answers

Answer:

Both particles A and B

Explanation:

A nucleus contains both protons and neutrons .

But protons are positively charged whereas neutrons have no charge.

[tex].[/tex]

Both particles A and B are most likely present inside the nucleus of the atom. Therefore, option (c) is correct.

What is the nucleus of an atom?

The nucleus of an atom contains the particles protons and neutrons. Both the solid particles in an atom are responsible for 99.9% of the mass in the nucleus.

The protons are the positively charged particles that lie inside the nucleus. Therefore, the nucleus of an atom has a positive charge on it while the negatively charged electrons rotate around the nucleus.

The neutrons do not carry any charge. So we can say that the neutrons are neutral. Therefore, the charge on the nucleus is only due to protons.

The atomic powers which are holding the protons and the neutrons inside the nucleus are also vast. The protons are prsent very close to each other inside the tiny nucleus, so the electrostatic forces of repulsion act in the nucleus.

Therefore, particles with no charge and positive charge are most present in the nucleus of the atom.

Calculate the empirical formula of a compound that has a composition of 5.9% (by mass) hydrogen and 94.1% (by mass) oxygen.​

Answers

Answer:

The empirical formula is the simplest form;

Given:

Oxygen O at 94.1% and

H at 5.9%

Assume 100grams.

94% = 0.941 x 100gm. = 94.1 gm x 1mole/16gm. = 5.88 moles of O

5.9% = 0.059 x 100gm. = 5.9gm. X 1moleH/1.002gm. = 5.88 moles of H

There is one mole of O for each mole of H so the empirical formula is [tex]O_1H_1[/tex]

and written as OH.
