The balanced chemical reaction is written as follows:
<span>bacl2 + na2so4 → baso4 + 2nacl
Therefore, the number of </span><span>chlorine atoms in the reactants side and the products side would be 2 atoms in both sides which should be the case because the number of atoms in each side should have the same number.</span>
This is one of the factors that affects chemical reactions
Temperature:This is because when the temperature is raised energy in form of heat is supplied to the reacting particles and so the rate of reaction is increased.
