or compound. A sample of si? Geologist know the mineral composition by analyzing the content of the element or compound. A sample of silver sulfide minerals, in addition to containing silver and sulfur, also contain elements of X (oxidation state +4). The mass of silver in this mineral magnitude 11.9 times the mass of X. A total of 10 grams of this mineral reacts perfectly with 295 mL of hydrogen gas at 400K and 1 atm and produce silver sulfide, H2S and the XS. Given R = 0.082 L atm / kmol.
a. Give the equation for mineral reaction with hydrogen. In minerals, assuming that the number of silver atoms and the number of atoms = a X = b, the other coefficients must be expressed in a and b
b. Calculate the total number of moles of hydrogen gas used in the reaction.
c. Count the number of moles of minerals, which are stated in amounts b
d. Calculate the ratio a: b
e. Calculate Ar X and specify the name of the element X
