Since an alpha particles is a helium nucleus, it involves the loss of 2 protons and 2 neutrons. As a result, the atom the loses an alpha particle decreases its mass number by four ( 2 protons and 2 neutrons) and decreases it's atomic number by 2 ( it loses two protons).

mars1129 [50]

Answer:

About 2 liters

Explanation:

Since 1 gallon equals 3.785 liters, you figure out how many liters per week she uses by 3.785 x 0.75 which is 2.83875. Then divide that by 7 which is 0.405535 liters per day. Then multiply that by 5 days which is 2.027 liters in 5 days.

What is one of the ways a fission reaction can get out of control? when there are too many neutrons when the neutrons are slowed
Juliette [100K]

Out of the following given choices;

A) when there are too many neutrons

B) when the neutrons are slowed down

C) when there is a chain reaction

D) when there is critical mass

The answer is A. A fission nuclear reactor is controlled by regulating the number of neurotoxins produced in the chain reaction. Too many neutrons cause an accelerated chain reaction that causes enormous heat to be generated in a short amount of time which could cause an explosion. Control rods , made of “neutron poisons”, e.g. cadmium, are put in the reactors to control the number of neutrons at any one time

If all the light waves are absorbed by an object then the object will apear what color
Alex_Xolod [135]

When light hits a surface, some of it is absorbed and some of it is reflected. The light that is reflected is the color of the object in that light. For example, a blue object absorbs all the colors of the spectrum except blue, it reflects blue light. hope this can help.
