You have two distinct gaseous compounds made from element X and element Y. The mass percents are as follows: Compound I: 30.43% X, 69.57% Y Compound II: 63.64% X, 36.36% Y In their natural standard states, element X and element Y exist as gases. (Monatomic? Diatomic? Triatomic? That is for you to determine.) When you react gas X with gas Y to make the products, you get the following data (all at the same pressure and temperature): 1 volume gas X + 2 volumes gas Y 2 volumes compound I 2 volumes gas X + 1 volume gas Y 2 volumes compound II Assume the simplest possible formulas for reactants and products in the chemical equations above. Then, determine the relative atomic masses of element X and element Y.

Sulfuric acid, H2SO4, can be formed from the chemical reaction 2SO2+O2+H2O--->2H2SO4. Suppose 400g of SO2; 175g of O2, and 125 g H2O are mixed and the reaction proceeds until one of the reactants is used up. How many grams of H2SO4 is produced?A. 612gB. 620gC. 622gD. 630g
A website promoting the use of alternative energy vehicles and hybrid technologies claims that, "A typical automobile in the USA uses about 4040 gallons of gasoline every month, producing about 750 lbs of carbon dioxide." To determine the truth of this statement, calculate how many pounds of carbon dioxide are produced when 40.0040.00 gallons of gasoline are subjected to complete combustion. Assume that the primary ingredient in gasoline is octane, C8H18(l),C8H18(l), which has a density of 0.703 g/mL.
barrels of toluene are being stored on the moon for use in onsite manufacturing. If each barrel contains 42 gallons, how many moles are in each container? The specific gravity of toluene is 0.867 and its molecular formula is C7H8. you may assume the molecular weights of carbon and hydrogen are 12 and 1 g/mol, respectively.
Each time you inhale, you take in about 5.0x10^2ml (two significant figures) of air, each milimeter of which contains 2.5x10^19 molecules. In deivering the Gettysburg Address, Abraham Lincoln is estimated to have inhaled about 200 times. How many molecules did Lincoln take in?

When you react "gas X" with "gas Y" to make the products, you get the following data (all at the same pressure and temperature): 1 volume "gas X" + 2 volumes "gas Y" → 2 volumes compound I 2 volumes "gas X" + 1 volume "gas Y" → 2 volumes compound II Assume the simplest possible formulas for reactants and products in the chemical equations above. Then, determine the relative atomic masses of element X and element Y.
Assuming that gasoline is 100% isooctane and that the density of isooctane is 0.792 g/mL, what mass of CO2 (in kilograms) is produced each year by the annual U.S. gasoline consumption of 4.6 X 1010 L?
Soda ash (sodium carbonate) is widely used in the manufacture of glass. Prior to the environmental movement much of it was produced by the following reaction. CaCO3 + 2 NaCl → Na2CO3 + CaCl2 Unfortunately, the byproduct calcium chloride is of little use and was dumped into rivers, creating a pollution problem. As a result of the environmental movement, all of these plants closed. Assume that 125g of calcium carbonate (100.09 g/mol) and 125 g of sodium chloride (58.44 g/mol) are allowed to react. Determine how many grams of useful sodium carbonate (105.99 g/mol) will be produced. How many grams of useless calcium chloride (110.98 g/mol) will be produced? You should also determine how many grams of excess reactants are left (indicate which one is the limiting reactant)
1.58g of magnesium hydrogencarbonate was added to a 1.68 mol/L solution of acetic acid, CH3COOH in water (50.0 mL), producing carbon dioxide gas, water and magnesium acetate, Mg(CH3COO)2. d) If 1.23 g of magnesium acetate was produced, what is the percentage yield of the reaction? e) What is the theoretical yield (in grams) of carbon dioxide from this reaction? f) The above reaction is performed in a closed 25 L container at 10 °C. Upon completion of the reaction, what will the final pressure of CO2 be inside the container?
Methane is produced in the human gut during digestion. As it passes through the digestive tract, it collects at thelower end and is emitted as flatulence. About 10% of a fart is composed of methane.__CH4 + __O2 → __ CO2 + __H2Oa) The average human fart contains 0.00643g of methane gas. Ifyou were to light said fart (and you SHOULD NOT), what mass ofoxygen would combust along with it?b) People, on average, pass 0.75L of gas per day. This is about0.0536g of methane per 24 hour period (remember, only ~10% ismethane). What mass of water could be generated by one personigniting their “methane emission”? c) How many water molecules is this? (SHOW ALL WORK IN TRAIN TRACKS)
