Nuclear power plants heat water to produce steam. The steam is used to spin large turbines that generate electricity. ... In nuclear fission, atoms are split apart to form smaller atoms, releasing energy. Fission takes place inside the reactor of a nuclear power plant.
The amount of N2O5 to start with would be 35.79 grams
<h3>Stoichiometric calculations</h3>
From the balanced equation of the reactions:
Mole ratio of N2O5 and NO2 = 1:2
Since the reaction's actual yield is 82%, the theoretical yield would be: 25 x 100/82 = 30.49 grams
Mole of 25 g NO2 = 30.49/46
= 0.66 mole
Equivalent mole of N2O5 = 0.54/2 mole
= 0.33 moles
Mass of 0.27 mole N2O5 = 0.33 x 108.01
= 35.79 grams

In physical chemistry and thermodynamics, the Gibbs free energy or ΔG is very important because it is the criterion for spontaneity. When the magnitude of ΔG is negative, the reaction is spontaneous. This means that the reaction readily occurs. When the magnitude is positive, the reaction is non-spontaneous. This means that in order for the reaction to proceed, you must apply external force like electricity.
For equilibrium reactions, there is a forward and reverse reaction written as: A+ B ⇆ C. Only one of those reactions is spontaneous. So, if the forward reaction is -ΔG, then the reverse reaction is the opposite which is +ΔG. The answer is letter A.
Answer: The mass of the sample is 1264.800 kg.
Explanation:
Mass of the piece of copper = m
Volume of the copper price =
m = 1,264,800 g = 1,264.800 kg (1 kg = 1000 g)
The mass of the sample is 1264.800 kg.
Answer:
0.657 grams of Sodium chloride.
Explanation:
Isotonic saline or normal saline contains 9 grams per litre of sodium chloride.
For 73 mL of isotonic saline :
1000 mL of isotonic solution contain 9 grams of NaCl
1 mL of isotonic solution contain grams of NaCl
73.0 mL of isotonic solution contain = 0.657 grams of NaCl
