Reducing the emissions of which gas will lead to reducing the greenhouse effect? a) oxygen b) nitrogen c) argon d) carbon dioxide

The correct answer is Option D.

Explanation:

Green house gases are defined as the gases that absorb heat and also emit radiant heat with infrared radiation. These gases contributes to the green house effect. The heat radiated from these gases get trapped in the Earth atmosphere and it then results in the rise of temperature of the Earth surface.

There are 4 main gases that are known as green house gases. These are carbon dioxide , methane , nitrous oxide and ozone . These gases also include chlorofluorocarbons also known as CFCs.

The reduction of any these gases will result in the reduction of greenhouse gases.

Thus, the correct answer is Option D.

- 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
