The equation for the ph of a substance is ph = –log[h+], where h+ is the concentration of hydrogen ions. what is the approximate ph of a solution if the concentration of hydrogen ions is 5.0 × 10–4 moles per liter?

pH = 3.3

Step-by-step explanation:

pH is given by the formula; pH = –log[H+]

The concentration of hydrogen ions is 5.0 × 10–4 moles per liter.

Therefore;

pH = - log₁₀(5.0 × 10^–4)

    = -( - 3.301)

    = 3.301

Thus;

The approximate pH will be; 3.3

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
