Answer:

It will decrease the pH of the water.

Explanation:

When carbon dioxide gets dissolved in water, it changes its pH.

The pH of water will become acidic.

In dissolved state, carbon dioxide forms carbonic acid with water as shown in the equation.

$H_{2}O+CO_{2}--->H_{2}CO_{3}$

This carbonic acid gets dissociated as shown in equation.

$H_{2}CO_{3}--->2H^{+}+CO_{3}^{-2}$

Due to increase in concentration of hydrogen ion, the pH of water decreases.

What shape would a molecule of carbon tetrachloride have?

Elden [556K]

Answer:

Tetrahedral

Explanation:

For the repulsion of the free electron pair theory, the shape of a molecule will be to repel the bonds and the free electrons on the central atom. In a molecule of carbon tetrachloride, the central atom (C) has no free electrons, so, the shape that repels better the charge is tetrahedral, as shown below.
