Hello!
In this case, since the kinetics of the radioactive decay is assumed to be first-order, it is possible to use the following equation to quantify that change:
Thus, given the elapsed time, 635 years, and the half-life, 1599 years, we can compute the fraction of the present amount:
Thus, the percent is:

Answer:
Synthesis
Explanation:
I just did the test and got it right!!
Answer:
The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy. In English, the equation says: <u><em>To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2). Energy will be released in the process.</em></u>
Explanation:
We are given the chemical reaction and the amount of reactant used for the process. We use these data together to obtain what is asked. We do as as follows:
0.882 mol H2O2 ( 1 mol O2 / 2 mol H2O2 ) = 0.441 mol O2 produced
Hope this answers the question.
