I think it’s 7.41 because you count up all the atoms and find out how many are x (the large grey ones) and you do 2/27 x 100 which gives you 7.41 :) (sorry if i counted wrong it’s kinda hard)
Answer:
atomic mass ( N =14 , H = 1×3 that means 14+3=17
340gram×17gram / mole
=5780mole
atomic mass ( H= 1×2 ,O= 16 =16+2 =18
90gram×18gram /mole
=1620mole
I think 340g ammonia (NH3)
To balance a chemical equation you must pay attention that the algebraic equation has the same number of element atoms in reactant and the product.
A chemical equation is a term to refer to the symbolic description of a chemical reaction, that is, the written representation of symbols. For example:
The balance of an equation can be related to the law of conservation of matter, that is, the number of atoms of each element in the reactants is in the result.
