Which of the following air pollutants causes a reddish-brown haze in the sky? sulfur dioxide carbon monoxide nitrogen dioxide carbon dioxide

The answer would most likely he sulfur dioxide

The answer is nitrogen dioxide

Explanation:

The term "photochemical smog" refers to a mist formed by a mixture of pollutants (NOx and volatile hydrocarbons) with others such as ozone, peroxyacyl, hydroxyl radicals, etc., which are formed by the reactions that occur with the light of the sun to affect the NO. This mixture dyes the atmosphere of a reddish brown color, full of very dangerous components for living beings.

- 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
