What will be the outcome of putting litmus paper into bleach?
a. red paper turns blue, blue paper turns red
b. red paper does not change, blue paper turns red
c. red paper turns blue, blue paper does not change
d. red paper does not change, blue paper does not change

The correct option is c

Explanation:

The major ingredient in household bleach is sodium hypochlorite (NaClO). This compound is a base and the bleach solution assumes this alkalinity status.

A base is a substance that produces hydroxyl/hydroxide ion (OH⁻) as the only negative ion when dissolved in water. The pH of a base is between 7 to 14. One of the major properties of base is that it turns red litmus paper blue and it has no effect on blue litmus paper.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
