How does the number of products in a synthesis reaction compare with the number of reactants?
a) the number of products is greater than the number of reactants
b) the number of products is less that the number of reactants
c) the number of products is the same as the number of reactants
d) the number of products may be greater or less than the number of reactants

The correct answer is Option B.

Explanation:

Synthesis reaction is defined as the reaction in which two or more substances combine in their elemental state to form a single compound.

The general equation representing this reaction follows:

As, number of reactants in this type of reaction will always be more bacuse a single product is forming in this reaction.

Thus, the correct answer is Option B.

- 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
