First we have to understand what a half life is. A half life is a measure of time when the amount of a certain object is 50% of the original amount. Hence the answer for this is letter A. The initial amount is 100. fifty percent of 100 is 50 and that happens after 15 hours. Hence, 15 hours is the half life period.

Find number atoms in each element?
____ [38]
1. Gypsum has the formula as CaSO₄.2H₂O<span>. Hence, CaSO₄ is bound with two H₂O. CaSO₄ has 1 Ca atom, 1 S atom and 4 O atoms. 2H₂O have 4 H atoms and 2 O atoms.
Hence,
      total Ca atoms = 1
      total S atoms = 1
      total O atoms = 4 + 2 = 6
      total H atoms = 4
      total number of atoms = 1 + 1 + 6 + 4 = 12

</span>2. Cellulose has the formula as C₆H₇O₂(OH)₃. But there are 2 molecules.<span> Hence, to find total atoms in each element, number of atoms should be multiplied by 2 .The elements of the cellulose are C, H, and O. Hence,
      total C atoms = 6 x 2 = 12
      total O atoms = (2 + 3) x 2 = 10
      total H atoms = (7 + 3) x 2 = 20
      total number of atoms = 12 + 10 + 20 = 42
</span>
3. The formula of the antiperspirant is Al₂Cl(OH)₅<span>. It has Al, Cl, O and H as the elements. Hence, the number of atoms in each element can be found as follows;
      total Al atoms = 2
      total Cl atoms = 1
      total H atoms = 1 x 5 = 5
      total O atoms = 1 x 5 = 5
      total number of atoms = 2 + 1 + 5 + 5 = 13</span>
