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

When ethyl acetoacetate (ch3coch2co2ch2ch3) is treated with one equivalent of ch3mgbr, a gas is evolved from the reaction mixtur

Advocard [28]

The protons of methylene group between the two carbonyl groups in ethylacetoacetate are acidic in nature. When compounds containing such acidic protons are treated with bases the loose proton and form enolates.
In this particular example when ethylacetoacetate is reacted with methyl magnesium bromide, the methyl group abstracts the acidic proton and converts into methane gas. The enolate when hydrolyzed is again converted into ethylacetoacetate as shown below,

Calculate the mass of oxygen released by the action of water on 10.0 grams of sodium peroxide (the other product is sodium hydro

lesya692 [45]

The reaction equation:
2H₂O + 2Na₂O₂ → 4NaOH + O₂

Moles of sodium peroxide = 10 / 78 = 0.128

Moles of oxygen released = 0.128 / 2 = 0.064 mol
Mass of oxygen = 0.064 x 32

Mass of oxygen = 2.05 grams
