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.
Water takes shape of the container that it is currently in. ( like a cylinder cup, or a cube shape)
Answer:
Mass = 2.8 g
Explanation:
Given data:
Mass of HCl = 102 g
Mass of Zn = 128 g
Mass of H₂ = ?
Solution:
Chemical equation:
2HCl + Zn → H₂ + ZnCl₂
Number of moles of Zn:
Number of moles = mass/molar mass
Number of moles = 128 g/ 65.38 g/mol
Number of moles = 2 mol
Number of moles of HCl:
Number of moles = mass/molar mass
Number of moles = 102 g/ 36.5 g/mol
Number of moles = 2.8 mol
Now we will compare the moles of hydrogen gas with HCl and Zn.
HCl : H₂
2 : 1
2.8 : 1/2×2.8 = 1.4 mol
Zn : H₂
1 : 1
2 : 2
Number of moles of hydrogen formed by HCl are less thus it will limiting reactant.
Mass of Hydrogen:
Mass = number of moles × molar mass
Mass = 1.4 mol × 2 g/mol
Mass = 2.8 g
