Question

7. Write a balanced chemical equation for the following reactions and label what type of reaction it is. (3 points)

a. Sodium hydroxide reacts with nitric acid
b. Hydrogen + bromine
c. Silver nitrate + aluminum chloride

Answer 1

a. Sodium hydroxide reacts with nitric acid

Naoh + Hno3 == Nano3 + h20.

acid based reaction.

b. Hydrogen + bromine

H + Br == Hbr

H2 + Br2 == 2Hbr synthesis reaction

c. Silver nitrate + aluminum chloride

3Agno3 + Alcl3 == Al (No3)3 + 3Agcl double displacement.

Answer 2

(A) Naoh + Hno3 == Nano3 + h20.
and it is acid based reaction.
(B) H + Br == Hbr. it is synthesis reaction
and it should be hydrogen gas with bromine gas if that was question then
H2 + Br2 == 2Hbr
(c) 3Agno3 + Alcl3 == Al (No3)3 + 3Agcl
it is double displacement. and we right the polyatomic ion in bracket that’s why no3 is in bracket.
please let me know if you need something
