The statement that is true is that B. Atoms always remain intact during chemical reactions.

Atoms simply mean the <u>basic units of matter.</u> They're the defining structure of an element. Atom is also known as the smallest unit of matter.

It should be noted that atoms always remain intact during chemical reactions. They cannot be added and removed when there are <em>chemical reactions.</em>

"calculate the ratio of the velocity of hydrogen molecules to the velocity of carbon dioxide molecules at the same temperature"
Ne4ueva [31]

Answer: 1:4.69

Explanation:

The ratio can be expressed as:

Ua/Ub= √(Mb/Ma)

Where Ua/Ub is the ratio of velocity of hydrogen to carbon dioxide and Ma is the molecular mass of hydrogen gas= 2

Mb is the molecular mass of CO2 = 44

Therefore

Ua/Ub= √(44/2)

Ua/Ub = 4.69

Therefore the ratio of velocity of hydrogen gas to carbon dioxide = 1:4.69

which implies hydogen is about 4.69 times faster than carbon dioxide.

A light twig is barely floating on the surface of water. What will most likely happen to the twig if a drop of dishwashing deter
horrorfan [7]

Answer;

- It will sink because soap disrupts the inter-molecular forces of water

Explanation;

-A light twig is barely floating on the surface of water. if a drop of dish washing detergent is added near it then it will sink because soap disrupts the inter- molecular forces of water.

-The twig was initially floating due to the force of surface tension created by the inter-molecular forces between water molecules. When soap is added to the water, the twig will be driven to sink by the disruption of the water's surface tension. This is because soap is a surfacant that is amphipathic and thus disrupts the inter-molecular forces between water molecules that are responsible for surface tension.
