The chemical equation for the formation of ammonia is unbalanced. 3H2(g) + N2(g) -----> NH3(g) If three molecules of hydrogen
mestny [16]

Answer: 2 molecules of ammonia

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced chemical equation for the formation of ammonia is:

3H_2(g)+N_2(g)\rightarrow 2NH_3

According to stoichiometry,

3 molecules of hydrogen combines with 1 molecule of nitrogen to give 2 molecules of ammonia.

Gases are measured in different units. Which of the following measurements of pressure are equal? Select all that apply.
viva [34]

Explanation:

Pressure of a gas is the combined force with which the molecules bombard a unit area of the wall of the container.

    1 atm  = 760mmHg

               = 760torr

               = 101325Pa

               = 101325Nm⁻²

 1mmHg  = 1torr

        1Pa = 1Nm⁻²

101.325 kPa  and 101,325 Pa are the same

           1000Pa = 1kPa

101,325 Pa  and 1 atm

1atm and 101.325 kPa
