Stoichiometry is a collective term for the quantitative relationships between the masses, the numbers of moles, and the numbers of particles (atoms, molecules, and ions) of the reactants and the products in a balanced chemical equation. I think.
Answer: Stoichiometry is a collective term for the quantitative relationships between the masses, the numbers of moles, and the numbers of particles (atoms, molecules, and ions) of the reactants and the products in a balanced chemical equation.
Explanation:
Stoichiometric Calculations are mostly based on chemical formulas. Formula Mass: It is defined as the sum of the atomic weights of each atom present in the molecule of the substance. For example formula mass of Na2S is calculated as 2(23) + 1(32) = 78.
Scientists were unsure about the last common ancestor between apes and humans because fossils are so scarce, researchers do not know what the last common ancestors of living apes and humans looked like or where they originated.
