Gaseous ammonia chemically reacts with oxygen (O2) gas to produce nitrogen monoxide gas and water vapor. Calculate the moles of ammonia needed to produce 0.085 mol of water. Answer is in moles, needs to be rounded to the nearest significant digit. I need to know the steps to getting there, since I already balanced the equation to make it 4 NH3 + 5 O2 = 4 NO + 6 H2O but I don't know the process used to get to how many moles of ammonia are needed to produce a certain amount of moles of water.

Describe in detail the melting point behavior of the 80: 20 benzoic acid-mandelic acid mixture

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced. be sure your answer has the correct number of significant digits.
