The answer would be the <span>Chemical formula for ammonia by
hydrogen and nitrogen gas: 1 N2 + 3 H2 --> 2 NH3 t<span>hen use stoichiometry. You know you have enough
nitrogen gas to react, so you can just straight convert mol H2 to mol NH3,
where 3 mol H2 = 2 mol NH3.
<span>3.44 mol H2 * (2 mol NH3 / 3 mol H2) = 2.29 mol NH3</span></span></span>
Answer: 38.6 ml
Explanation:
Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.
(At constant pressure and number of moles)

= initial volume = 17 ml
= final volume = ?
= initial temperature =
=final temperature=


Thus final volume is 38.6 ml at 70
Answer;
-Macroscopic properties remain constant
-Concentrations remain constant
-No change to copper solution seen;
-Rate of reverse/backwards reaction = rate of forward reaction;
Explanation;
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system.
-It is a a condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs. A reversible chemical reaction is one in which the products, as soon as they are formed, react to produce the original reactants.
