If 0.57 moles of carbon monoxide gas are produced by the following reaction, how many grams of silicon dioxide and of carbon were reacted (assume just enough of each)? Express your answer to two decimal places. SiO2(s) + 2 C(s) → Si(l) + 2 CO(g) Mass of SiO2 needed:  Mass of C needed:

When propane (C3Hg) reacts with oxygen, carbon dioxide and water are produced. The balanced equation for this reaction is C3 Hs (g) + 502 (g) → 3CO2(g) + 4H2O(g) If 10 moles of oxygen react, The reaction consumes moles of propane (C3H8). The reaction produces moles of carbon dioxide and moles of water.

For the following reaction, 0.497 moles of sulfur are mixed with 0.217 moles of carbon monoxide. What is the formula for the limiting reagent? What is the maximum amount of sulfur dioxide that can be produced? sulfur(s) + carbon monoxide(g) -> sulfur dioxide(g) + carbon(s)

For the reaction, calculate how many grams of the product form when 3.6 g of CaO completely reacts. Assume that there is more than enough of the other reactant.CaO(s)+CO2(g)→CaCO3(s)CaO(s)+CO2(g)→CaCO3(s) Express your answer using two significant figures.

Nitrogen and hydrogen combine at a high temperature, in the presence of a catalyst, to produce ammonia. N₂ (g) + 3 H₂(g) → 2NH₂(g) Initially, there are 0.100 mol N₂ and 0.330 mol H₂ present. How many moles of ammonia are produced after the reaction has gone to completion? moles of NH3: What is the limiting reactant? O hydrogen nitrogen How many moles of H₂ remain after the reaction has gone to completion? moles of H₂: mol mol

Consider the following balanced chemical reaction: HNO3 + 3H2 → NH2OH + 2H2O If 25.0 grams of HNO3 were mixed with 8.70 grams of H2 gas, how many grams of the excess reagent (i.e. either H2 or HNO3) would remain once the reaction is complete?  Molar mass of HNO3 = 63.01 g/mol Molar mass of NH2OH = 33.03 g/mol

Sulfur dioxide gas reacts with sodium hydroxide to form sodium sulfite and water. The unbalanced chemical equation for this reaction is given below: SO2(g) + NaOH(s) → Na2SO3(s) + H2O(l) Assuming that you start with 55.3 g of sulfur dioxide and 32.3 g of sodium hydroxide and assuming that the reaction goes to completion, determine the mass of each product formed. -----gNa2SO3 -----gH2O
