Answer:
CaCO3 + 2HCl ---> CaCl2 + H2O + CO2
Explanation:
The reaction between solid calcium carbonate and a mineral acid such as aqueous HCl is a neutralization reaction and occurs with the evolution of CO2 gas.
The balanced equation is given below
CaCO3 + 2HCl ---> CaCl2 + H20 + CO2
The product CaCl2 is water soluble which accounts for why the stain is removed, while CO2 gas escapes away from the reaction surface.
m/s² aka meter per second squared.
acceleration = change in velocity/time
= distance/time

time
= m/s

=m/s^2
The heat in particles travels through convection at a certain speed depending on what density a mass has.
