As 1 g of sodium hydroxide dissolves in 100g of water, the conductivity of the water:
1. decreases
2.increases
3. remains the same

The conductivity of the resulting solution will increase.

Explanation:

The conductivity of the solution obtained by adding sodium hydroxide in water will increase as compared to pure water due to complete dissociation of sodium hydroxide into sodium ion and hydroxide ions. The conductivity increases on increase in number of ions in a solution.

The conductivity depends upon

a) number of ions

b) mobility of ion.

- 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
