You had to heat caco3 strongly in order for it to decompose. this is an example of an endothermic reaction. what does this tell you about the energy stored in the reactants compared to the energy stored in the product? write the balanced equation for the decompostion of caco3 this time with the term "+ energy "on the appropriate side of the equation

Here's what I get  

Explanation:

1. Addition of heat

The energy stored in the reactant is less than the energy stored in the products.

We had to add heat energy so the reactant would convert to products.

2. Balanced equation

CaCO₃ + heat ⟶ CaO + CO₂

hi my dude or dudette

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
