It would be (1) magnesium.
hope this helps :D
Hydronium ion is H3O(+)
pH is log 1 / [H3O(+)] = - log [H3O(+)]
Rainfall: pH = 5.0 = - log [H3O(+)] => [H3O(+)] = -antilog (- 5.0) = 10^-5
Water; pH = 7.0 = - log [H3O(+)] => [H3O(+)] = - antilog (-7.0) = 10^ -7
Divide hidronium conentration of rainfall by hidrodium concentration of water:
10^-5 / 10^-7 = 10^2 = 100.
Then, hidronium concentration in rainfall is 100 times hidronium concentration in water.
Answer: option a. 100 times.
Answer:
A
Explanation:
particles are frozen and hence will vibrate in their fixed positions
Molarity =wt/M.wt * 1000/V
=> 1.77 = wt/180 * 1000/555
> wt = 1.77 * 180*555 /1000 = 176.823 g
