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
It will either be B or D, but I don't know about burial.
a.The gas pressure will decrease.
Explanation:
If in a rigid container, the amount of gas particles and volume of the container is held constant, the pressure will decrease if the temperature is reduced.
- Gases are highly random particles and they require a high amount of kinetic energy to be in their state of matter.
- In a condition where volume of container is fixed, the amount of gas particles is fixed and the temperature reduced, the kinetic energy of the gas particles will directly reduce.
- The kinetic energy of gases is directly related to temperature.

Answer:
A monosaccharide that contains 4 carbon atoms, one of which is in an aldehyde group, is classified as an aldotetrose.
Explanation:
A tetrose is a monosaccharide with 4 carbon atoms.
They have either an aldehyde functional group in position 1 (aldotetroses).
or a ketone functional group in position 2 (ketotetroses).
So, A monosaccharide that contains 4 carbon atoms, one of which is in an aldehyde group, is classified as an aldotetrose.
