The time needed for a substance becomes half of it mass is called half-time, after. In this case, the half time is 100 minutes. Then to know how much substance remain after 200 minutes the equation would be:

Substance remains= 1/2^(time/half-time) x substance initial mass

Substance remains = 1/2^(200 minutes/100minutes) x 1 times= 1/4 times

Pretty sure its 30 percent

Here are some rules:

1. The oxidation state of a free element (uncombined element) is zero.2. For a simple (monatomic) ion, the oxidation state is equal to the net charge on the ion.3. Hydrogen has an oxidation state of +1 and oxygen has an oxidation state of −2 when they are present in most compounds.

The oxidation number of Fe in Fe(NO3)2 is +3.

Answer:

1300cm3.

Explanation:

Step 1:

Data obtained from the question.

Initial temperature (T1) = K

Initial volume (V1) = 650 cm3

Final temperature (T2) = double the original = 2K

Final volume (V2) =..?

Step 2:

Determination of the new volume of the gas.

The new volume of the gas can be obtained by using Charles' law as follow:

V1/T1 = V2/T2

650/K = V2/2K

Cross multiply

K x V2 = 650 x 2K

Divide both side by K

V2 = 650 x 2K /K

V2 = 650 x 2

V2 = 1300cm3.

Therefore, the new volume of the gas is 1300cm3
