What is the R-group of an amino acid?

Chemistry

Answer:

Every amino acid has another atom or group of atoms bonded to the central atom, the R-group. This "R-group", also known at the side chain, gives each amino acid proteins specific characteristics (size, polarity, pH).

If the atomic number of Chlorine atom is 17 and atomic mass is 35.5u, compute the number of protons, electrons and neutrons.
lord [1]

Answer:

Protons= 17, Electrons= 17, Neutrons= 18

Explanation:

The atomic number (Z) corresponds to the number of electrons that is equal to the number of protons (17). The mass number (A) corresponds to the sum of protons and neutrons present in the nucleus (35). Therefore, we calculate the number of neutrons: 35-17 = 18

According to Le Châtelier's principle, what happens if heat is added to a system?
Dmitrij [34]

Answer: Option (B) is the correct answer.

Explanation:

According to Le Chatelier principle, when a system is in equilibrium then any change in the reaction will shift the equilibrium in a direction which is opposing the change.

For example, when heat is added to a system the molecules will gain kinetic energy. So, rate of reaction will increase hence, product formation will increase but equilibrium will shift in the opposite direction.

Hence, we can conclude that according to Le Chatelier's principle, the reaction shifts to remove the heat if heat is added to a system.

What is the process when oceans and lakes collect water that has fallen (water cycle)
arsen [322]

The water cycle is the endless process that connects all of that water. It joins the Earth's oceans, land, and atmosphere. The Earth's water cycle began about 3.8 billion years ago when rain fell on a cooling Earth, forming the oceans. ... Precipitation that falls onto land flows into rivers, streams, and lakes.

The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, surface runoff, and subsurface flow. In doing so, the water goes through different forms: liquid, solid (ice) and vapor.

As a car slows down, its kinetic energy increases.<br> True<br> False
Softa [21]

Answer:

False.

Explanation:

Kinetic energy represents the energy the car has and is using right now. So, if the car was fast, then it would have a lot of kinetic energy. A slow car has a low amount of kinetic energy.
