33.23 grams of a thin sheet of iron is completely oxidized in 7 days. How would you express the rate of conversion of the silver
tresset_1 [31]

Answer:

A. 0.0440 moles/day

Explanation:

First, let's figure out how many moles 33.23 grams of silver is. We do this by dividing the number of grams by the molar mass of silver, which is 107.87 g/mol:

33.23 g Ag ÷ 107.87 g/mol = 0.3081 mol Ag

Now, let's divide this by 7 to get the rate per day:

0.3081 mol Ag ÷ 7 days = 0.0440 mol/day

Thus, the answer is A.

An HCl solution has a concentration of 9.8 x 10-5 M. What is the pH of this solution?
Inessa05 [86]
HCl = H⁺ + Cl⁻

c(HCl)=9.8*10⁻⁵ mol/l

pH=-lg[H⁺]

[H⁺]=c(HCl)

pH=-lg{c(HCl)}

pH=-lg{9.8*10⁻⁵}=4.009

pH=4.009
