Answer:
4
Explanation:
Data obtained from the question include:
[H3O+] = 0.0001 M
pH =?
pH is the negative logarithm of the hydrogen ion or hydronium ion. It is written as:
pH = - Log [H3O+]
Now inputing the value of [H3O+] into the equation above, the pH value can be obtained as follow illustrated below
pH = - Log [H3O+]
[H3O+] = 0.0001 M
pH = - Log 0.0001
pH = 4
Therefore, the pH of the solution is 4.
Answer:
Charles' Law
Explanation:
Charles' law states that at constant pressure, the volume of a fixed mass of gas is directly proportional to the absolute temperature. This implies that as the temperature of the gas is increased, the volume of the gas also increases and as the temperature is decreased, the volume also decreases.
From the question given above, we were told that as the gas warms ( i.e increase in temperature), it expands to fill the fill the balloon. This is clearly charles' law because the volume of the gas increased with increasing temperature.
