I have coronia virus say something positive to help me through

you're a strong person so keep on keeping on.

Explanation:

I hope you get better and stay positive also please stay safe

Explanation:

Synthesis of water: is limiting reactant ; is excess reactant

Synthesis of ammonia: is limiting reactantt ; is excess reactant

Combustion of methane: is limiting reactant ; is excess reactant

Explanation:

In a chemical reaction, if a reactant is totally consumed when the reaction is completed,it is called the limiting reactant/reagent , while the other reactant is called the excess reactant/reagent. The product formed is limited because the reaction stops abruptly as one of the reactant is consumed completely.

In order to determine which is the limiting reactant in a particular chemical reaction:

Calculate the amount of product formed if the first reactant were completely consumedRepeat this calculation for the second reactant.The reactant that produces the smaller amount of product is the limiting reactant. Synthesis of water
