Answer : Option C) A meltdown.
Explanation : When a nuclear fission reaction is conducted, and if it loses its control it will produce many neutrons which will be difficult to bring under control; for this purpose the nuclear reactors are built with the control rods which absorb the extra neutrons and help the reaction to be in control.
If this is not done, it may result in complete meltdown of the reactor as neutrons have high energy in them.
Answer:
4 NH3 + 5 O2 = 4 NO + 6 H2O
Explanation:
Balance to have equal atoms on both sides.
Answer:
5.42 mL needed to be added and 1.04 M of dilute solution
Explanation:
For both cases, you need to use the expression:
M1*V1 = M2*V2
where M and V are concentration and volume.
For the 1st question, we have both concentrations, but we do not have both volume so:
3 * V1 = 0.325 * 50
V1 = 0.325 * 50 / 3
V1 = 5.42 mL need to be added.
For question 2:
Same as above, with the difference that we need to calculate concentration so:
12 * 4.35 = M2 * 50
M2 = 12 * 4.35 / 50
M2 = 1.04 M is the concentration of the diluted solution
