Answer:
Al + 4AgNO3 >>Al(NO3)3+ 3Ag
Explanation:
the number of moles of No3 of the products is 3 therefore we have to balance the reactants by adding 3 before the "AgNO3" which also leades us to adding 3 mols to Ag on the products side
For the first one it’s 69 just count the little lines from the side.
Chlorine is a halogen and all halogens and oxygen, nitrogen and hydrogen are diatomics
I am going to be honest i’m good at chemistry but i need the point cause i need help on my history work
