<span>With the deer population down because many are killed, insects and ticks will starve. With less bugs, the lizards and frogs will have less to eat which means their population would lower as well.As their population lowers the population of their consumers will lower too</span>
Answer:
0.0556 mL of 90 M HCl would be taken and 9.944 mL distilled water added to make 0.5 M, 10 mL HCl solution.
Explanation:
From the dilution equation:
<em>Initial molarity (m1) x initial volume (v1) = final molarity (m2) x final volume (v2).</em>
In this case, m1 = 90 M, v1 = ?, m2 = 0.5 M, and v2 = 10 mL
v1 = m2 x v2/ m1 = 0.5 x 0.01/90 = 0.0000556 L
v1 = 0.0556 mL
This means that the initial volume of 90 M HCl to be taken is 0.0556 mL. Since the final volume to be prepared is 10 mL,
10 - 0.0556 = 9.944 mL
<em>Hence, 0.0556 mL of 90 M HCl would be taken and 9.944 mL distilled water added to make 0.5 M, 10 mL HCl solution.</em>
