<h3>Further explanation
</h3>
The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.
Usually radioactive elements have an unstable atomic nucleus.
General formulas used in decay:

T = duration of decay
t 1/2 = half-life
N₀ = the number of initial radioactive atoms
Nt = the number of radioactive atoms left after decaying during T time
Nt=25 g
No=100 g
t1/2=5770 years

Answer:
all you need if yo look up and say do plants grow without soil but yes they can grow without soil but they cannot grow without the necessities that soil provides.
Is 2.0 x 10 to the -9th power an option
Answer:
The density of the swimmer is 0.0342 lbm/in3.
This value makes sense as the density of the body is very similar to the water.
Explanation:
If the swimmers is floating, the weight of the swimmer must be equal to the upward buoyant force.
We can express the weight force as the product of density and volume of the swimmer.
Then

It makes sense as the density of the body is very similar to the water.
Cl2 is acting like a catalyst because it came out in a same state.
and it's homogeneous reaction because they are all gases.
