Answer:
C I think from what I did to solve!!
Coal produces more pollution than any other energy source
Answer:
H2S.
Explanation:
That would be H2S, hydrogen sulphide. (Smells like bad eggs!).
Assuming that nitrogen gas is ideal, we can use the equation PV = nRT to relate first conditions to the second condition. At constant temperature, pressure and volume are indirectly related as follows:
P = k / V
k is equal nRT
P1V1 = P2V2
P2 = 101.325 ( 4.65 ) / .480 = 981.586 kPa
Answer:
0.010 $.
Explanation:
Hello!
In this case, since 1 troy ounce equals 31.1 grams, we can compute the price of gold per gram first:

Now, we need to compute the grams of copper in 5.17 x10¹⁷ atoms via the Avogadro's number:

Thus, the price is:
