I rember when I learned this in 3rd grade
158 kJ. if you convert into moles and then divide by the number on the table you should get this
The energy of a nuclear reactor gets converted to electricity by using steam. As steam converts mechanical energy to electricity.
Answer: Option C
<u>Explanation:
</u>
Nuclear reaction works on the principle of nuclear fission. The main functioning of nuclear reactor is the generation of neutrons by fission of Uranium oxide.
The rate of generation of neutrons need to be controlled in the reaction to have a controlled chain reaction which is suitable for generating electricity.
So, the controlling of rate of nuclear generation is done by moderators. The moderators are generally water or graphite in any nuclear reactor. So during these process, steam is produced in the reactor core which then flows through a turbine engine.
The steam rotates the turbines in the generator and thus the mechanical energy of the turbine during rotation is converted as the electrical energy in the generator.
Considering a reaction:
A → B
The rate equation may be described as:
r = -k[A]ⁿ
Taking the natural log,
ln(r) = -nln([A]) + ln(k)
Therefore, the only time the graph of ln[A] vs time will be a straight line is when the order of the reaction is 0, meaning the reaction is independent of reactant concentration.
Answer:
<u>Metalloid -</u>
A metalloid is a chemical element with properties intermediate between those of typical metals and nonmetals
<u>Alloy</u> -
An alloy is a mixture of metals or a mixture of a metal and another element. Alloys are defined by a metallic bonding character.
