These are the reactants in the chemical equation 2 H2 + 02 --> 2 H20

Chemistry
1 answer:
stepan [7]3 years ago

Answer:

2H₂ + O₂

Are reactants in given chemical equation.

Explanation:

Chemical equation:

H₂ + O₂   → H₂O

Balanced chemical equation:

2H₂ + O₂   → 2H₂O

Tow moles of hydrogen H₂ react with one mole O₂  and produced two moles of water.

The given reaction completely hold the law of conservation of mas.

Reactants:

2H₂

O₂

Product:

2H₂O

Coefficient with reactant and products:

H₂      2

O₂      1

H₂O   2

When it comes to equilibrium reactions, it useful to do ICE analysis. ICE stands for Initial-Change-Equilibrium. You subtract the initial and change to determine the equilibrium amounts which is the basis for Kc. Kc is the equilibrium constant of concentration which is just the ratio of products to reactant. 

Let's do the ICE analysis

      2 NH₃ ⇄ N₂ + 3 H₂
I         0        1.3    1.65
C     +2x       -x      -3x
-------------------------------------
E       0.1        ?        ?

The variable x is the amount of moles of the substances that reacted. You apply the stoichiometric coefficients by multiplying it by x. Now, we can solve x by:

Equilibrium NH₃ = 0.1 = 0 + 2x
x = 0.05 mol
Therefore,
Equilibrium H₂ = 1.65 - 3(0.05) = 1.5 mol
Equilibrium N₂ = 1..3 - 0.05 = 1.25 mol

For the second part, I am confused with the given reaction because the stoichiometric coefficients do not balance which violates the law of conservation of mass. But you should remember that the Kc values might differ because of the stoichiometric coefficient. For a reaction: aA + bB ⇄ cC, the Kc for this is

K_{C} = \frac{[ C^{c} ]}{[ A^{a} ][ B^{b} ]}

Hence, Kc could vary depending on the stoichiometric coefficients of the reaction.

nadezda [96]

Answer:

It is A).

Explanation:

Silver (Ag) goes from the  pure metal to Ag+ losing 1 electron so it is oxidised.

The hydrogen ion  gains electrons and is reduced.
