Answer:

Explanation:
Hello,
In this case, for us to compute the final volume we apply the Boyle's law that analyzes the pressure-volume temperature as an inversely proportional relationship:

So we solve for
by firstly computing the initial pressure:


Finally, we can compute the work by using the following formula:

Best regards.
The anode in a voltaic cell is the source of electrons so it is considered to be negative. The counterpart is the cathode, which is considered to be positive. If you look at the diagram the electron flow goes from A to B. This means that part A is the anode. Part B is the cathode. Part C and D is the electrolyte.
The answer therefore is the first option.
The amount of Silicon left after 300 years is 75g
It is given that the initial amount of Si is 100 times decay is 300 years and the half-life of Silicon is 710 years.
The radioactive decay formula is given by,
A = A₀ x 2^(-t/h);
where;
A is the resulting amount after t time, Ao is the initial amt (t=0),t is the time of decay, and h is the half-life of the substance.
On substituting the values from the given we get,
A = 100x2^(-300/710)
A = 100 x 0.746112347
A = 74.6112347 grams left after 300 yrs
Therefore, the number of grams of silicon left after 300 years is 74.6112347g. This value could be rounded off to 75 grams as in the whole number
