How does the number of hydrogen atoms compare to the number of oxygen atoms in ribose

Ribose C5H10O5

Explanation:

Ribose is a carbohydrates with the formula C5H10O5. This molecule is pentose monosaccharide which has linear form of  H−(C=O)−(CHOH)4−H. The hyoxyl groups lie in the same side in the form of Fischer Projections.

The number of hydrogen atoms are double in number of the oxygen atoms. The ribose sugar is found in the RNA.

It is the genetic material which is found in some of the organism that carries information from one generation to another.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
