Science

3. reactant - the reactant in a chemical reaction that limits the amount of product formed.
6. analysis - the sequential application of conversion factors expressed as fractions and arranged so that any dimensional unit can be cancelled out until the desired set of dimensional units is obtained.
8. yield - the ratio of the actual yield to the theoretical yield of a material.
9. mass - the mass, in grams, of a mole of a substance.
11. statement - a statement that shows the quantities and units that are equal to each other.
14. - the calculation of the quantities of reactants and products involved in a chemical reaction.
16. mass unit - equals 1/12 the mass of a carbon atom.

1. factor - a ratio expressed as a fraction that equals one.
2. number - the number of atoms in a mole, equal to 6.02x10^23 atoms.
4. yield - the amount of product formed from the complete conversion of a limiting reactant in a chemical reaction.
5. formula - the simplest formula of a compound expressed as the smallest possible ratio of the elements.
7. ratio - the ratio of moles of one substance to the moles of another substance in a balanced equation.
10. composition - the percentage by mass of each element in a compound.
12. formula - a formula which states the exact number and type of each atom present in a molecule of a substance.
13. volume - the volume of one mole of any gas at standard temperature and pressure.
15. reactant - the reactant in a chemical reaction that remains when a reaction stops once the limiting reactant is completely consumed.
17. - The SI unit that measures the amount of matter a substance has; one mole is equal to 6.022x10^23 representative particles, also known as Avagadro's number.
