Answer:
A) H2O > HCCH > NH3 > CH3CH3
Explanation:
H2O is known as a neural compound which a pH close to 7.0. This however makes it more acidic due to it having the lowest pH when compared to the others in the option.
The other options however have their acidic strength as follows: HCCH > NH3 > CH3CH3. This explains why the pattern of decreasing acidic strength is H2O > HCCH > NH3 > CH3CH3

Explanation:
Ideal gas law, Charles law, Boyle's law.
<u>Explanation:</u>
Gas laws:
Charles law: Volume of a gas is directly proportional to the temperature.
V∝T
Boyle's law : Pressure of a gas is inversely proportional to the volume of a gas at constant temperature.
PV= k
Ideal gas law is the combined law of Charles and Boyle's law, PV = nRT.
