Photosynthesis, the process by which plants combine carbon dioxide and water to produce glucose and oxygen gas, is show in the balanced chemical equation below. How many grams of glucose (C6H10O6), can be produced from a carbon dioxide sample that exerts a pressure of 825 mm Hg, occupies 3.75 L...

A gas is either H2, N2, F2, or Cl2. Based on the following information about a sample of the gas, what is its identity? A 2.50 L sample of the gas exerts a pressure of 1.75 atm, has a mass of 6.7534 g and is at a temperature of 27.0 degreesC. Thanks in advance!

While naming chemical formulas I had a problem. Copper (II) Nitride Lead (IV) Oxide I assumed it was Cu(2+) and N(3-) and once you switch them around you get Cu3N2. But the correct answer is Cu3N. What am I doing wrong??? And also I thought it was Pb(4+) and O(2-) to be Pb2O4, but the...
