The equation for the nuclear fusion reaction is,
4 ¹₁H → ₂⁴He + 2 ₁⁰e
Calculation of mass defect,
Δm = [mass of products - mass of reactants]
= 4(1.00782) - [4.00260 + 2(0.00054858)]
= 0.0275828 g/mole
Given that,
Mass of Hydrogen-1 = 2.58 g
The no. of moles of ₁¹H = 2.58 g / 1.00782 = 2.56 moles
Therefore, the mass defect for 2.58 g of ₁¹H is,
= 2.56 moles * (0.0275828 g / 4) = 0.01765 x 10⁻³ kg
Energy for (0.01765 x 10⁻³ kg) is,
= (0.01765 x 10⁻³ kg) (3.0 x 10⁸)² = 1.59 x 10¹² J

Explanation:
As the earth rotates from west to east. So the eastern hemisphere receives the sunlight faster than the western hemisphere and when as the earth rotates on its axis time also keeps on changing from Eastern to western hemisphere. As when there will be day in eastern hemisphere the western hemisphere will have night there. and as the earth rotates it affects the day . so in this way they are related.

Answer:
Mean rate of reaction produced = 0.533 g/sec (approx.)
Explanation:
Given:
Reaction produced = 1.6 gram
Time taken = 30 sec
Find:
Mean rate of reaction produced
Computation:
Mean rate of reaction produced = Reaction produced / Time taken
Mean rate of reaction produced = 1.6 / 30
Mean rate of reaction produced = 0.533 g/sec (approx.)
Chromatography is really based on the principle where molecules in mixture are applied onto the surface or into the solid, also the fluid stationary phase. it is separating from each other while moving with the aid of a mobile phase. thats how i describe it but ion know how you do i tired.
