I need help with these 7 questions about percent yield percent error in chemistry. The instructions state to answer all the questions and to writea balanced chemical equation for each question as well. Please provide an explanation for each solution (on paper because typed answers aren't easy to understand). Thank you!

1. If 12.5 g of copper are reacted with an excess of chlorine gas (Clz), 25.4 g of copper (II) chloridel are obtained. What is the percent yield? Equation: Answer: 2. If 5.45 g of potassium chlorate are decomposed with a 78.2% yield, what mass of oxygen was released? The other product is potassium chloride. Equation: Answer: 3. What is the actual yield (in grams) of sulfuric acid if 15.0 g of sulfur trioxide reacts with water in a process with g 85.4% yield? Equation: Answer:
4. Compute the percent yield of the reaction when 193 g of ammonium bromide is collected from the synthesis of 35.0 g of ammonia (NH3) and hydrogen bromide. Equation: Answer: 5. How what is the percent error if 3.50 x 1023 molecules of C02 are produced in the decomposition of 72.0 g of cobalt (II) carbonate? Cobalt (ll) oxide is the other product. Equation: Answer: 6. Using the equation from problem #5 above, what is the mass of cobalt (ll) oxide is collected if 50.0 g of Cocoa decomposes with g 89.0% yield?
7. If 1.24 g of N02 is collected when 3.95 x 1023 molecules of 02 reacts with excess nitrogen monoxide, calculate the percent error of the reaction. Equation: Answer:
