Nuclear reactors found in nuclear power plants use uranium as a fuel for a fission reaction. Which statement below best describe

s this process?
A.
Two uranium nuclei are forced to collide at high speeds and they stick together releasing enormous amounts of heat. This heat causes other uranuim nuclei to collide and this process produces surplus heat to convert water to steam.
B.
A uranium nucleus is bombarded wtih a neutron which causes it to split and release heat and more neutrons. Those neutrons collide with other uranium nuclei. This process releases large quantities of heat that convert water to steam.
C.
Uranium nuclei are lined up in the reactor chamber so that when the first uranium is bombarded wtih an alpha particle, it causes that uranium to collide with the next uranium. Each of these collisions produces excess heat in large quantities which converts water to steam.

The nuclear fission process of the power plant bombards the uranium element with a neutron to start a series of reactions to release a large amount of energy. Thus, option B is correct.

<h3>What is nuclear fission?</h3>

Nuclear fission is a process of generating energy by the collision of the neutron particle with the element. The element under collision splits and releases more neutrons.

As the neutrons are produced they collide with more elements resulting in more energy. It is used to convert water into steam and generate electricity.

Therefore, option B. the neutron collides with elements to produce energy in a nuclear power plant.

Be sure to answer all parts. Nitric oxide (NO) reacts with oxygen gas to form nitrogen dioxide (NO2), a dark brown gas: 2NO(g) +
notka56 [123]

<u>Answer:</u> NO is the limiting reagent in the given reaction and 0.857 moles of NO_2 will be produced.

<u>Explanation:</u>

Limiting reagent is defined as the reagent which is present in less amount and it limits the formation of products.

Excess reagent is defined as the reagent which is present in large amount.

For the given chemical reaction:

2NO(g)+O_2(g)\rightarrow 2NO_2(g)

We are given:

Moles of NO = 0.857 mol

Moles of oxygen = 0.498 mol

By stoichiometry of the reaction:

If 2 moles of NO reacts with 1 mole of oxygen gas.

So, 0.857 moles of NO will react with = \frac{1}{2}\times 0.857=0.4285mol of O_2

As, the given amount of oxygen gas is more than the required amount. So, it is considered as an excess reagent.

Thus, NO is considered as the limiting reagent because it limits the formation of products.

By Stoichiometry of the reaction:

If 2 moles of NO produces 2 moles of nitrogen dioxide gas.

So, 0.857 moles of NO will produce = \frac{2}{2}\times 0.857=0.857mol of NO_2

Hence, NO is the limiting reagent in the given reaction and 0.857 moles of NO_2 will be produced.

If a question cannot be tested and observed, it cannot be answered with science. (2 points) True or False?
boyakko [2]

Answer:

True

Explanation:

If a question cannot be tested and observed, it cannot simply be answered by science.

Science works with observable and testable ideas and not on metaphysics.

  • Science presents a methodical approach into investigating phenomenon and answering likely questions in a logical manner.
  • The body of facts and data gathered through observations and tests are used to ramify the conclusion of a scientific study.
  • Without such, it is impossible to do the work of science.

A large piece of iron was reacted with an acid. What would happen to the rate of the reaction had the large piece been finely di
MAXImum [283]

Answer:

D: It will increase because smaller particles provide more surface area to react.

Explanation:

When the large iron is broken up into smaller pieces, there are more places for the iron to react (meaning there's more surface area). Think of it like taking the surface area of a big cube compared to the surface area of a bunch of small cubes. The sum of the surface areas of the small cubes will be greater than that of the large cube. As a result, more places for the iron to react will cause for a greater reaction.
