Ca + 2 H2O ------> Ca(OH)2 + H2 so 2 moles of calcium react with 4 moles of water.
Balanced equation: 2H2S + 302 = 2SO2 + 2H20
7.54 mol of K
Since molecules of potassium contain only single potassium atoms, molecules of iodine contain two atoms, and moles of potassium iodide contain one atom of each element, 2.5 moles of iodine are needed to react completely with 5 moles of potassium.
How many moles of C are needed to react with 0.490 mole SO2?
Assuming that all gases in this reaction are at STP, what number of molecules of hydrogen chloride gas are needed to completely react with oxygen to yield 50.00 mL of chlorine
4 moles
Balanced equation: 2H2S + 302 = 2SO2 + 2H20
7.54 mol of K
10 moles of nitrogen dioxide are needed to react with 5,0 moles of water.
H2 +Cl2---------------->2HCl Since H2 and Cl2 react in 1:1 mole ratio the number of moles of H2 reacting is equal to the number of moles of Cl2 which is equal to 0.213
Since molecules of potassium contain only single potassium atoms, molecules of iodine contain two atoms, and moles of potassium iodide contain one atom of each element, 2.5 moles of iodine are needed to react completely with 5 moles of potassium.
How many moles of C are needed to react with 0.490 mole SO2?
Assuming that all gases in this reaction are at STP, what number of molecules of hydrogen chloride gas are needed to completely react with oxygen to yield 50.00 mL of chlorine
The answer is 50 moles SiO2.
4 C3H8 + 20 O2 ---> 12 CO2 + 16 H2O So 20 mol of O2 are needed.
We need to know the number of moles of WHAT is to react with the butane to provide you with an answer.
N2 + 3H2 -> 2NH3 3 moles hydrogen gas. You should know that because of the formula of ammonia.
