Chemistry

sertanlavr [38]1 year ago

The moderator of a nuclear reactor is a substance that slows neutrons down. In traditional nuclear reactors, the moderator is the same thing as the coolant: it’s water! When fast neutrons strike the hydrogen atoms in H2O, they slow down a lot (like a billiard ball striking another). There are other good moderators like graphite, beryllium, and more.

<h3>What is moderator ?</h3>

Other neutrons are released at extremely high speeds when an incoming neutron splits an atom's nucleus. A sustained chain reaction is achievable if at least one (on average) of these neutrons can be made to split another fuel atom. In fact, if a neutron is traveling slowly, fuel atoms (like uranium) are more likely to absorb it (see Figure 1). In order to make a chain reaction easier to achieve, moderators are used in many reactor designs.

Neutrons can be slowed down more effectively in some materials than others. Because of the rules of conservation of energy and momentum, a neutron (mass 1) colliding with a heavy nucleus like a fuel atom cannot significantly slow down (mass 235).

How many moles of H2O2 are needed to react with 1.07 moles of N2H4?
I am Lyosha [343]

Answer:

2.14 moles of H₂O₂ are required

Explanation:

Given data:

Number of moles of H₂O₂ required = ?

Number of moles of N₂H₄ available = 1.07 mol

Solution:

Chemical equation:

N₂H₄  +   2H₂O₂       →   N₂ +  4H₂O

now we will compare the moles of H₂O₂ and N₂H₄

                          N₂H₄     :      H₂O₂  

                            1           :        2

                            1.07      :         2×1.07 = 2.14 mol

Answer:

2.68 cm^3

Explanation:

Density= Mass/Volume

so...

8.96 g/cm^3 = 24.01 g/ V

and then u solve so it would be 2.68 cm ^3

Which statement is correct regarding the rate of the reaction below? 3A + B 4X + 2Y The rate of disappearance of B is three time
V125BC [204]
First, let's write the givens in the form of a chemical equation:
3A + B ...................> 4X + 2Y

Now we find that this equation implies the following:
For every 4X and 2Y formation, 3A and 1B must disappear (react).

Comparing this implication to the above choices,  we find that the right answer is: <span>The rate of formation of X is four times the rate of disappearance of B.</span>
