Mmm, you can work this one out in your head by reversing it.
<span>12.5 = 50g/4 </span>
<span>1/4 = 1/2 * 1/2 </span>
<span>thus in 14.4 seconds there have been 2 times the half life. 14.4/2 = 7.2 </span>
<span>the half life is 7.2 seconds.</span>
Answer: see the last column in the final table of the explanation below.
Explanation:
1) Arrange the data to understand the question:
<span>Acid Molarity Moles of H⁺ released per liter
HCl 1 ____
H2SO4 1 ____
H3PO4 1 ____
H2SO4 0.5 ____
H3PO4 3 ____
HNO3 2 ____
</span><span>
2) All the given acids are strong acids, so you can consider they dissociate completely and release all the hydrogens present in the chemical formula.
3) The molarity formula is M = n/V, where n is the number of moles of solute and V is the volume of the solution in liters
From that, n = M×V
Go one by one with that formula.

Acid Molarity Moles of solute number of H in Moles <span><span>H⁺ </span> per liter the chemical formula per liter
HCl 1 1M×1L = 1 1 1×1 = 1
H₂SO4₄ 1 1M×1L = 1 2 2×1 = 2
H₃PO₄ 1 1M×1L = 1 3 3×1 = 3
H₂SO₄ 0.5 0.5M×1L = 0.5 2 2×0.5 = 1
H₃PO₄ 3 3M×1L = 3 3 3×3 = 9
HNO₃ 2 2M×1L = 2 2 2×2 = 4

Answer and Explanation:
Biological molecules contain many different types and combinations of functional groups which will affect its properties, structure, solubility, and reactivity.
A few of the most important chemical functional groups in biological molecules are: Sulfhydryl, Amine, Hydroxyl, Carboxyl, Carbonyl, Thiol, Amino, and Phosphate.
So, check your complete question and anyone in your options that I didn't list here is the correct answer.
