Question

PLEASE HELP I’VE BEEN STUCK ON THIS FOR A WHILE EVEN IF YOU’RE NOT SURE I JUST NEED AN ANSWER ILL MARK BRAINLIEST TOK


1) Is the equation for Reaction 1 balanced? Explain your reasoning. If the reaction is not balanced, then state how you would balance it. Then, provide the balanced equation.

2) Is the equation for Reaction 2 balanced? Explain your reasoning. If the reaction is not balanced, then state how you would balance it. Then, provide the balanced equation.

3) What kind of reaction do you think Reaction 1 represents (Just write your best prediction)

4) What kind of reaction ri you think Reaction 2 represents? (Just write your best prediction)

Answer 1

Reaction 1:
First of all this reaction is balanced because you have the same amount of reactants in the side of products. I guess it’s a gas evolution reaction.
Reaction 2:
This reaction is not balanced. The balanced form is:
CaCl2+(2)NaHCO3=>CO2+CaCO3+H2O+(2)NaCl
And it was not balanced because it doesn’t follow conservation of mass rule. I think it’s a precipitation gas evolution reaction.
