Answer:
1) km 2) cm^ 3) no units (kg cancels) 4) g/cm^3 5) g 6) g°C
Explanation:
Like units will cancel ((m/km)*(km) = m
Non-cancelled units remain (ml)*(g/ml)*(°C) = g°C
Too freaking many... or maybe not many at all
Answer:
10
Explanation:
pH is defined as the negative logarithm of the concentration of hydrogen ions.
Thus,
pH = - log [H⁺]
Thus, from the formula, more the concentration of the hydrogen ions or more the acidic the solution is, the less is the pH value of the solution.
Thus, solution with pH = 3 will be more acidic than solution with pH =4
Thus, concentration of the [H⁺] when pH =3
3 = - log [H⁺]
[H⁺] = 10⁻³ M
For pH = 4, [H⁺] = 10⁻⁴ M
<u>hence, pH = 3 is 10 times more acidic than pH = 4</u>
The answer is adduction lol
