The mole percent of methane to water in clathrate compounds that contain methane hydrate is 1:5.75. In these methane clathrate deposits, only 1% w/w is the methane hydrate and rest are minerals and regular ice. Estimate the amount of methane gas that can be produced by heating 3.5 kg sample of clathrate. (А) 1.34 g (В) 27 g (С) 35 g (D) 4.7 g

Chlorine is used by textile manufacturers to bleach cloth. Excess chlorine is destroyed by its reaction with sodium thiosulfate, Na2S2O3, as follows:Na2S2O3(aq) + 4Cl2(g) + 5H2O  2NaHSO4(aq) + 8HCl(aq)   Using the concepts established in the previous parts, answer the following questions about the following reaction:The octane in gasoline burns according to the following equation:2C8H18 + 25O2 → 16CO2 + 18H2O(a) How many moles of O2 are needed to react fully with 6.84 mol of octane?   (b) How many moles of CO2 can form from 0.511 mol of octane?   (c) How many moles of water are produced by the combustion of 8.20 mol of octane?   (d) If this reaction is used to synthesize 6.00 mol of CO2, how many moles of oxygen are needed? How many moles of octane are needed?    ? mol O2 ? mol C8H18   Thanks.

Ammonia (NH3) is an important compountd is used in large amounts for the manufacture of nitrogenous fertilizers, nylon and many other important compounds. It is manufactured by the catalytic reaction between nitrogen between nitrogen and hydrogen, according to the following equation; N2(g) +H2(g) = NH;(g) When 1.20 mol nitrogen and 1.20 mol hydrogen are mixed together in a closed vessel, 30% of the nitrogen is converted into ammonia. a. Calculate the moles of nitrogen gas that will be present in the vessel? (only 3 decimal places) mol b. Calculate the moles of hydrogen gas that will be present in the vessel? (only 3 decimal places) mol c. Calculate the moles of ammonia gas that will be present in the vessel? (only 3 decimal places) Activate W mol d. What is the number of moles of nitrogen gas that has reacted? (only 3 decimal places) 10:09 Links 18°C 1O 23-Nov-21
