Answer:
The correct answer is They provide the molar ratio of reactant and products in a chemical reaction.
Explanation:
Balanced chemical equation helps us to calculate the number of moles of both reactant and product.For example
2H2+O2=2H2O
From the above balanced equation it can be stated that 2 molecules of hydrogen(H2) reacts with 1 molecule of oxygen(O2) to form 2 molecules of water.
<span>During an avalanche, potential energy of the snow on the mountain is converted to kinetic energy as the snow cascades down. The conversion of potential energy to kinetic energy is due to the compacted atoms in the snow which will accumulate other snow resulting to a bigger snow that causes avalanche.</span>
A colorless, toxic, radioactive gas is called, bioaccumulation.
