Because if they are not balanced, then the amount of reaction is not equal to the amount of the product. You must have the same ratio of atoms on both sides of the equation because we are not losing moles of each element.
The heat in particles travels through convection at a certain speed depending on what density a mass has.
Answer: Mutations are important to the evolution of a species because is creates new DNA for a certain gene, creating a new allele.
Hope this helps!!! Good luck!!! ;)
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.
