Which water resource is most likely to dry up for part of the year?

Ponds

Explanation:

Ponds are defined as small and large water bodies that are surrounded by land on all of its sides. In simple words, they are comprised of stagnant water bodies. They receive water mostly from the rainfall and the nearby rivers.

When there occurs changes in the weather and climatic conditions, such as low or absence of rainfall, then rapid evaporation takes place, as a result of which the water is released into the atmosphere, making the pond dry.

So, the ponds are most likely to be dry for some part of a year.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

the answer is c i believe
