Joe collected 94 stamps altogether. He collected 27 in April and 34 in May. How many did he collect in June?
inna [77]
If Joe collected 94 stamps which are in April May and June, we could make an equation like this: A + M + J = All stamps

Plug in the values:
27 + 34 + j = 94
Isolate J:
j = 94 - 27 - 34
Combine like terms:
j = 33
He collected 33 stamps in June.

The hydrogen ion concentration (h+) in a certain cleaning compound is (h+)=3.2x10^-11 use the formula ph=-log(h+) to find the pH
Furkat [3]

Answer:

The pH of the clean compound is approximately 10.495.

Step-by-step explanation:

If the cleaning ion concentration of the cleaning compound is [H^{+}] = 3.2\times 10^{-11}, then the pH, no unit, of the compound is:

pH = -\log_{10} [H^{+}]  (1)

pH = -\log_{10} (3.2\times 10^{-11})

pH = -\log_{10} 3.2 - \log_{10} (10^{-11})

pH = -\log_{10} \frac{32}{10} +11

pH = -\log_{10} 32 + \log_{10} 10 + 11

pH = -\log_{10} 32 +12

pH \approx 10.495

The pH of the clean compound is approximately 10.495.
