In a laboratory experiment, 27.5 g of Cu were reacted with 125 g of HNO3 (63.01 g/mol):
3 Cu + 8 HNO 3 Cu(NO3)2 + 4H2O + 2 NO
a. How many grams of Cu(NO3)2 (187.57 g/mol) can be theoretically produced?
b. How many grams of excess reactant remain?
c. If the percent yield of Cu(NO3)2 is 87.3%, what is the actual yield in grams?

The diagram below shows the different phase transitions that occur in matter. which arrow represents the transition in which dew is formed?

What is the molecular formula of ferrous nitrate and ferric nitrate

When hydrogen peroxide (h2o2) is added to potassium iodide (ki) solution, the hydrogen peroxide decomposes into water (h2o) and oxygen (o2). the chemical equation for the decomposition reaction is: 2h2o2—> 2h2o + o2. what is the role of the potassium iodide in this reaction? a. reactant. b. product. c. precipitate. d. catalyst.
