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

metric time was an attempt to create a standard unit of time based off of 10, but it never took off an is not included in the metric system (si)

it's 3.2 on edge, i just took the test.
