the states of the reactants and products
the temperature and pressure at which the reaction was carried out
the relative amounts of reactants and products
the type of catalyst that is used to speed up the reaction
whether the reaction can go in both directions
Explanation:
A chemical equation is an equation that shows how the reactants are combining together to give the products.
The following are the information to include when writing a chemical equation;
- the states of the reactants and products
whether solid, liquid or gases or aqueous, It is usually appended as a subscript in bracket
- the temperature and pressure at which the reaction was carried out
this shows the condition under which the reaction was carried out. It also gives useful information that can be used to quantitatively determine heat changes in a reaction.
- the relative amounts of reactants and products
this is usually derived from the balanced equation. They are the numbers appended at the beginning of the species in the equation
- the type of catalyst that is used to speed up the reaction
it is a good practices to provide the information about the catalyst used.
- whether the reaction can go in both directions
→ signifies one direction
⇔ both directions

Answer:
0.0300 moles of H₂
Explanation:
The original equation is PV = nRT. We need to change this to show moles (n).
n = 
It's important to convert your values to match the constant (r) in terms of units.
30.0 kPa = 0.296 atm
2500 mL = 2.50 L
27 °C = 300 K
Now, plug those values in to solve:
n = 
- for the sake of keeping the problem clean, I didn't include the units but you should just to make sure everything cancels out :)
Finally, you are left with n = 0.0300 moles of H₂
