B. Those who could not be broken down chemically anymore than they already were
The answer is 1) mixing of two gases by diffusion.
Once 2 gases are mixed by diffusion, they cannot be obtained from the mixture of gases. Hence, it is considered to be an irreversible process.
Answer:
T½ = 16hours
Explanation:
Final mass (N) = 10g
Initial mass (No) = 20g
Time (t) = 16hours
T½ = ?
T½ = In2 / λ
But λ = ?
In(N/No) = -λt
In(10/20) = -(λ * 16)
In(0.5) = -16λ
-0.693 = -16λ
λ = 0.693 / 16
λ = 0.0433
Note : λ is known as the disintegration constant
T½ = In2 / λ
T½ = 0.693 / 0.0433
T½ = 16hours
The half-life of the sample is 16hours
Answer:
H2 + O2
Explanation:
H2 + O2 --> H2O
The items on the left side is the reactants. The arrow means yields, and the item the arrow is pointing at is the product.
Answer:
The object moves up.
Explanation:
I think that's the answer because since F was up that would cause 5 N . To go up.
Tell me if I'm wrong, plz :D
