SnSe2
GaAs
Pb(SO4)2
Be(HCO3)2
Mn2(SO3)3
Al(CN)
i need to find their names

Explanation:

SnSe2 = Tin (IV) selenide

GaAs = Gallium arsenide

Pb(SO4)2 = Lead(II) sulfate

Be(HCO3)2 =Beryllium Bicarbonate.

Mn2(SO3)3 = Manganese(III) Sulfite.

Al(CN)3  =Aluminum Cyanide

hope it helps :)

the answer is a and have a great day

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
