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.

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
