Water is a highly important natural resource. which of these would be the best method to conserve water? a) drinking bottled water b) monitoring the ph of rivers c) treating and re-using wastewater d) testing nitrate levels in groundwater

Option (C) is the correct answer.

Explanation:

Water is a natural resource of water and life without water is not possible. As it is one of the basic necessities essential for survival of human beings, plants, trees, animals etc.

Therefore, it is important to save water by purifying or treating impure water so that it becomes suitable for use. Also, we can re-use waste water for different purposes except drinking.

Thus, we can conclude that the best method to conserve water is treating and re-using wastewater.

the answer is c

Explanation:

i took the test and i got it right

- 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

its first and third is your answer i did the qustion the fourth isnt right
