The energy transferred between samples of matter because of a difference in their temperatures is called a. heat. b. thermochemi
Evgesh-ka [11]

Answer:

The energy transferred between samples of matter because of a difference in their temperatures is called a. heat.

Explanation:

The first law of thermodynamics establishes that when two bodies with different temperatures are put in contact they will find thermic equilibrium to a final temperature by transferring heat. Thus the correct answer is (a).

Thermochemistry is the study of the transformations of heat energy on the chemical reactions. Chemical kinetics is the study of the rate of chemical reactions. And temperature is the measure of the heat.

What type of reaction is : CaCo3+ HCl = CaCl2 + CO2 +H2O
Pavlova-9 [17]

Answer:

Double decomposition reaction

Explanation:

When hydrochloric acid reacts with any carbonates/hydrogen carbonates the products formed are metal chloride , water and carbon dioxide.Since HCl decomposes salts of weaker acids.

So the equation of the reaction between calcium carbonate and HCl is:

CaCO3+2HCl =CaCl2+H2O+CO2

This reaction is also known as double decomposition reaction.
