Answer: $3CO_2$

Explanation: A molecule of compound is formed by the combination of atoms of different elements combined together in a fixed ratio by mass.

Carbon dioxide is a covalent compound formed by sharing of electrons between carbon and two oxygen atoms in which less electronegative atom is named first followed by the more electronegative element with a prefix indicating the number of atoms followed by an -ide.

The number is represented by a stochiometric coefficient in the beginning of chemical formula.

Thus the correct representation of 3 molecules of carbon dioxide is $3CO_2$

2) $6.17\ \rm m/s$

Explanation:

<u>Given:</u>

The angle that falling raindrops make with the vertical= $18^\circ$

Let $V_R$ be the velocity of the raindrops and $V_B$ be the velocity of the bus.

$\dfrac{V_R}{V_B}=\tan 18^\circ\\\dfrac{V_R}{V_B}=0.315\\$

2)Speed of the raindrops $=0.315\times 19$

$=6.17\ \rm m/s$
