Force can be added together

1 answer:

7 0

Forces can be added only when they both are going in the same direction as 2n +2n = 4n of force in the same direction if they are 2 facing forces they would <span>have had to be subtracted, which ever force is greater that will be the momentum of the force.

Hope this helps.</span>

Cellular Respiration is the process of what? A. Producing oxygen at the cellular level. B. The release of energy from food. C. B

matrenka [14]

Cellular Respiration is the process of the release of energy from food. Hence, option B is correct.

<h3>What is cellular respiration?</h3>

Cellular respiration is the process by which organisms use oxygen to break down food molecules to get chemical energy for cell functions.

Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.

Hence, option B is correct.

1. Use your knowledge of valence electrons and how they affect bonds to figure out how carbon (Group 14) and oxygen (Group 16) w

erik [133]

From the fact that oxygen is in group 16 and carbon is in group 14, the structure of CO2 must be O=C=O. In methane, there is no bond between any of the hydrogen atoms. The structure of H2O2 is H–O–O–H.

Carbon is in group 14 hence it has four valence electrons and oxygen is in group 16 hence it has six valence electrons. This implies that each oxygen atom will share four electrons with carbon in a covalent bond to form the structure O=C=O.

In CH4, we know that carbon is tetravalent so it forms for bonds. Therefore, there is no bond between hydrogen atoms so it bonds with each hydrogen atom; hydrogen only forms one bond.

In H2O2, there is the peroxide ion that has the structure O-O. Hence, the correct structure of H2O2 is H–O–O–H.
