Caffeine, a stimulant in coffee and some cola drinks, is 49.47% carbon, 5.19% H, 28.8% N, and 16.48% O. What is the mass of carbon contained in 37.1 g of caffeine?

Caffeine, a stimulant in coffee and some cola drinks, is 49.47% carbon, 5.19% H, 28.8% N, and 16.48% O. What is the mass of carbon contained in 37.1 g of caffeine?

What volume of carbon dioxide, measured at room temperature and pressure, would be obtained by the reduction of 320g of iron(III)oxide?

I get confused as to how to set up these type of equations. Any assistance would be greatly appreciated.

What three conversion factors and in what order would you use them to convert the mass of a compound into atoms of a articular element in that compound-- for example, from 1.00 g aspirin (C9H8O4)...

Using the balanced equation 6SO2+6O2=6SO3+3O2 if 96.0 g of SO2 reacts with 32.0 g O2 what mass of the product will form?

I need to know what formula to use and how to calculate the moles of potassium sulfate produced and the grams of water produced

74grams of H2 gas and an excess of O2 gas reacts to form H2O according to the reaction below. What mass of H2O is produced? 2 H2(g) + O2(g) > 2 H2O(g)

20 moles of Pb(NO302 will produce blank moles of PbCrO4. If you start with 5.5 grams of lead nitrate, how many grams of potassium nitrate will be produced.

KCl + Pb The product would be There would be no reaction I am pretty sure, but can you explain why please?

Al2O3 The product would be Al + O2 I am pretty sure, but can you explain why please?

If 107.00 g of Na3P react how many grams of NaF would be produced? Formula 2Na3P + 3CaF2 = 6NaF + Ca3P2 (already balanced)

Equation: 2 Mg + CO2 = 2 MgO + C (already balanced) 71.66 g of Mg react with 91.25g of CO2. What is the limiting reagent in the reaction? What is the theoretical...

Formula: CaCO3 + 2HCl = CaCl2 + H2O + CO2 (already balanced) How many moles of CaCO3 reacted? Theoretically, how many grams water should be produced? Answer...

If 107.00 g of Na3P react how many grams of NaF would be produced? Formula 2Na3P + 3CaF2 = 6NaF + Ca3P2 (already balanced)

Idk what Molarity is someone explain it to me Please haha

Oxygen reacts with 22g of C5H10 producing CO2 and water. What will the volume of CO2 produced at STP?

The numbers in the equation are subscripts *in front of compound are coefficients to balance the equation please show your work, so i can see how you did it(:

Chemistry

3Al(a) + 3NH4ClO4(s) = Al2O3(s) + AlCl3(s) + 3NO(g) + 6H2O (g)

SiCk4(g) +2Mg(a) =2MgCl2(aq) +Si(s)
