Answer:
Hydrogen ion concentration is more conveniently expressed as pH, which is the logarithm of the reciprocal of the hydrogen ion concentration in gram moles per liter. Thus, in a neutral solution the hydrogen ion (H+) and the hydroxyl ion (OH−) concentrations are equal, and each is equal to 10−7. A pH of 7 is neutral
<h2>
Answer:Volume of the container will decrease</h2>
Explanation:
Given that the gas is trapped,so the gas cant escape.
The number of moles of gas inside the container will remain constant.
The initial and final pressures are the same.
So,pressure can be taken as constant.
Charles law states that at constant temperature,volume of a system is directly proportional to the temperature of the system.
Since the temperature is lowered,volume also decreases.
I think that you didn't copy the answers correctly, because 1 and 2 are the same, and 3 and 4 are also the same here.
Anyways, the answer which is correct is that an electron has a charge of -1, and a proton has a charge of +1.
Electrons are negatively charged, whereas protons are positively charged. Neutrons are neutral.
