Answer:
A) fission
Explanation:
Fission reactions require a critical mass. The critical mass is necessary because it makes a fission reaction self sustaining. This critical mass is the minimum amount of material required. Nuclear fission additionally depends on the composition, purity and concentration of the fissile material. Critical mass is important in the design of nuclear warheads.
Answer:
Part 1: 2KNO3 → 2KNO2 + O2 is the balanced equation.
Part 2: The conversation of mass that demonstrates that there is no detectable change in the total quantity of matter present in the
Explanation:
Part 1: To balance a chemical equation, the number of atoms in the reactants and the products must be equal. So, the coefficient 2 added before KNO3 and KNO2 to balance the equation.
2KNO3 → 2KNO2 + O2
Part 2:
This chemical reaction demonstrates the conversation of mass that demonstrates that there is no detectable change in the total quantity of matter present when chemical change occurs (matter converts from one type to another) or physical change occurs (changes among solid, liquid, or gaseous states).
This is clear in the balanced equation.
Oh come on now, give me a break ! Have you thought about it yet ?
Do you know how many states there are all together in the USA ?
At the present time, there are 50 states all together.
If 24 of them are on one side, then how many are on the other side ?
Isn't it (50 - 24) ? Can you do the subtraction ?
One substance can be separated from another through physical means
