The reaction 2 no(g) + cl2(g) → 2 nocl(g) is carried out in a closed vessel. if the partial pressure of no is decreasing at a ra
BARSIC [14]

Answer:

92.0 torr/min.

Explanation:

  • For the reaction: <em>2NO(g) + Cl₂(g) → 2NOCl(g).</em>

∵ The rate of the reaction = - 1/2(ΔP)NO/Δt = - (ΔP)Cl₂/Δt = 1/2(ΔP)NOCl/Δt.

∵ (ΔP)NO/Δt = - 184 torr/min.

<em>∴ The rate of change of the total pressure in the vessel = - 1/2(ΔP)NO/Δt</em> = (- 1/2)(- 184 torr/min) = <em>92.0 torr/min.</em>

I will give brainiest! PLEASE ANSWER ASAP.How does the law of conservation of mass apply to this reaction: C2H4 + 3O2 → 2H2O + 2
blondinia [14]
<h3>Answer:</h3>

The law of conservation of mass has already been applied. There is an equal number of each element on both sides of the equation.

<h3>Explanation:</h3>

<u>We are given;</u>

  • The equation;

C₂H₄ + 3O₂ → 2H₂O + 2CO₂

We need to ask ourselves the following questions;

Is the equation balanced?

  • Yes, the equation because the number of atoms of each element is equal on both sides of the equation.
  • That is; Reactants: 2 carbon atoms, 4 hydrogen atoms and 6 oxygen atoms.
  • Products: 2 carbon atoms, 4 hydrogen atoms and 6 oxygen

What is the law of conservation of mass?

  • According to the law of conservation of mass, the mass of reactants should always be equal to the mass of the products in chemical reactions.

What makes the equation obey the law of conservation of mass?

  • For an equation to obey the law of conservation of mass, it must be balanced.
  • In this case, <u>the equation given is already balanced and therefore obeys the law of conservation of mass</u>.
