Match term definition

alcohol a) extremely long molecule chain with repeated molecular units

ether b) contains an oxygen and hydrogen (−o−h) bonded to a carbon

carbonyl group c) contains a carbon atom double-bonded to an oxygen atom

polymer d) contains an oxygen bonded within the carbon chain

The answer to your question is:

Explanation:

Alcohol   B) Contains an oxygen and hydrogen (−O−H) bonded to a carbon

Polymer A) Extremely long molecule chain with repeated molecular units

Ether D) Contains an oxygen bonded within the carbon chain

Carbonyl group C) Contains a carbon atom double-bonded to an oxygen atom

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.

- 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
