How many nitrate ions are in 2 mol of iron (II) nitrate

Chemistry
1 answer:
Allisa [31]2 years ago
7 0

Answer:

Two

Explanation:

Nitrate has a charge of negative 1 and the Iron (II) tells us the iron in that formula has a charge of +2, so in order for the iron to have to equal positive two, there has to be two negative. Since on nitrate ion is -1, you need two to make -2.

Answer: I'm in no way like an expert but I've heard water goes from an elevated area to a lower area. So it should be arrows that start at a more elevated to less elevated. Like white to brown, and orange to yellow, and stuff like that. I hope that helped? Anyway, have a lovely day!

3. Which one is part of the kinetic molecular theory? Yes = part of KMT, No = not part
lidiya [134]

Explanation:

a. Average kinetic energy is directly proportional to absolute Kelvin temperature of a gas.

Yes

b. There are no attractive forces and repulsive forces between gas molecules.

Yes

C. Atoms are neither created nor destroyed by ordinary chemical reactions.

No

d. The volume occupied by all of the gas molecules in a container is negligible compared to  the volume of the container

Yes

The kinetic molecular theory is one of such theories used to explain the forces between molecules and the energy they posses.

According to the theory;

  • The temperature of gas is proportional to the average kinetic energy.
  • Molecules are independent of one another and the force of attraction and repulsion between them is negligible.
  • volume occupied by gases is negligible compared to the volume of the container.

Law of conservation of matter states that "atoms are neither created nor destroyed by ordinary chemical reactions".

Calculate the mass ratio of S to O in SO, and then calculate the mass ratio of S to O in SO2, given that the mass of S is approx
ziro4ka [17]

Explanation:

From the knowledge of law of multiple proportions,

mass ratio of S to O in SO:

mass of S : mass of O

= 32 : 16

= 32/16

= 2/1

mass ratio of S to O in SO2:

= mass of S : 2 × mass of O

= 32 : 2 × 16

= 32/32

= 1/1

ratio of mass ratio of S to O in SO to mass ratio of S to O in SO2:

= 2/1 ÷ 1/1

= 2

Thus, the S to O mass ratio in SO is twice the S to O mass ratio in SO2.

B. It shifts the equilibrium toward the right, favoring product.
PilotLPTM [1.2K]

Answer:

11) the difference in heat energies between products and reactants

12) enthalpy change

Explanation:

The heat of reaction is defined as that energy released or absorbed as chemical substances participate in a chemical reaction. It is a term used to denote the change in energy as reactants change into products.

Another name of heat of reaction is enthalpy of reaction. It is a state function since it depends on the initial and final states of the system.
