NAME Hour 1. What mass of H,0 can be produced from 3.25 g H, and 41.8 g O,? Grams 3.25 g 41.8 g 2H, O2 2H,0 REACTION Molar Mass Moles Mole:Mole Which reactant was the limiting reactant? What was the theoretical yield? If 25 grams of water was actually produced, what was the % Yield?

Consider the following balanced reaction. How many moles of C3H7SH are needed to produce 0.235 moles of CO2? Assume excess 02. C3H7SH (1) + 6 O2(g) → 3 CO2(g) + SO2(g) + 4H2O(g) Your Answer: Answer units

In the unbalanced chemical equation shown above for the combustion of ethanol, what least common multiple whole number coefficient should go in front of the hydrocarbon (C2H5OH) to balance the equation?    See image below

What is the easiest process to get to the result?

Consider the reaction: C2H4 + O2     →     CO) (Unbalanced).  If 0.96 g of C2H4 g was Used 5.2 g of CO2 produced, calculate the percentage yield in the reaction. (Hint Balance the equation first).

To produce zinc metal, carbon monoxide reacts with zinc (I1) oxide according to: Zno + CO - Zn + CO2 The carbon monoxide, however, is initially prepared from: 2C+ 02 → 200 How many grams of zinc metal (Zn) may be prepared if If 81.0g of C is used with excess amount of ZnO? Your answer should be numerical and neglect units (e.g., if you calculate 3.5g then input 3.5).

balance this  equation  N2 +O2→O2 and if you have 10.grams of N2 gas how many grams of NO2 are produced in in reaction ?

FeSO4   +   Potassium phosphate  à  Iron (II) phosphate  +  K2SO4 State the Molar Ratio of the reaction.

For the following reaction, 6.61 grams of benzene (C6H6) are mixed with excess oxygen gas. The reaction yields 18.6 grams of carbon dioxide.benzene (C6H6) (l) + oxygen (g) carbon dioxide (g) + water (g) What is the ideal yield of carbon dioxide?  grams What is the percent yield for this reaction?  %

Label the following chemical equation: 6CO, + 6H,0 C,H,O + 60 12 6 :: Yields (produces/equals) : Reactants ("ingredients") : Subscript :: Products :: Coefficient 2.
