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
