How many moles of h2o are needed to consume 12 moles of na in the following reaction 2 na plus 2 h2o 2 naoh plus h2?
Since the given reaction is already balanced, simply divide 12 by the coefficient of Na in the equation, resulting in a quotient of 6. Multiply the coefficients of the original equation by 6 to obtain the answer: 6 X 2 = 12 moles of water required.
(Note that the equation should have been written with mostly capital letters as follows: 2 Na + 2 H2O -> 2 NaOH + H2.)

If 309 moles of FeCr2O7 react how many moles of O2 will be consumed?
To determine how many moles of O2 are consumed when 309 moles of FeCr2O7 react, we first need the balanced chemical equation for the reaction. Assuming FeCr2O7 decomposes to yield Fe, Cr, and O2, a typical reaction could produce 3 moles of O2 for every mole of FeCr2O7. If this is the case, 309 moles of FeCr2O7 would consume 3 × 309 = 927 moles of O2.

Which is the limiting reactant when 3.00 moles of calcium are reacted with 8.00 moles of water in the following equation?
To determine the limiting reactant, you must compare the moles of each reactant to the stoichiometry of the reaction. The balanced equation is essential to determine the ratio of moles needed for the reaction. In this case, 3.00 moles of calcium and 8.00 moles of water are given, and you can find which reactant limits the reaction by finding out which reactant would require more moles for complete reaction based on the stoichiometry.
According to the following balanced reaction how many moles of NO are formed from 8.44 moles of NO2 if there is plenty of water present?
If the reaction is not specified, we can't determine the exact moles of NO formed from NO2 based on this information alone. The reaction and stoichiometry are needed to calculate the moles of NO produced from 8.44 moles of NO2.
How many moles ofBa3(PO4) could be formed from 3.25 moles of Na3PO4 and 7.03 moles of Ba(NO3(2 in the following reaction?
Ba3(PO4) is an incorrect formula. Barium phosphate has the formula 'Ba3(PO4)2 '. So write down the BALANCED reaction eq'n. 2Na3PO4 + 3Ba(NO3)2 = 6NaNO3 + Ba3(PO4)2 The molar ratios are 2:3 :: 6:1 We have 3.25 mol(Na3PO4) equivalent to '2' & 7.03 mol(Ba(NO3)2 ) equivalent to '3' We now must find the limiting reactant. So 3..25 / 2 = 1.625 & 7.03/3 = 2.34333.... We only need 1.625 moles(Na3PO4) to react with 7.03 moles (Ba(NO3)2). So at 3.25 moles the sodium phosphate is in excess. Therefore 7.03 moles barium nitrate is the limiting reactant. By equivalence 3:1 ;; 7.03 : x Hence x /1 = 7.03 / 3 x = 7.03 x 1 / 3 x = 2.34333... moles(Ba(NO3)2) is produced.

How many moles of water are needed to react with 2.5 moles of sodium?
The balanced chemical equation for the reaction between sodium and water is: 2 Na + 2 H2O -> 2 NaOH + H2 Since 2 moles of water are needed to react with 2 moles of sodium, 1 mole of water is needed to react with 1 mole of sodium. Therefore, 2.5 moles of sodium will require 2.5 moles of water for the reaction.
The reaction of hydrogen with nitrogen to produce ammonia is shown below. If there are 3 moles of nitrogen how many moles of hydrogen are needed to react completely with the nitrogen?
The balanced equation for the reaction is: 3H2 + N2 -> 2NH3 From the balanced equation, we can see that 3 moles of hydrogen are needed to react completely with 1 mole of nitrogen. So if there are 3 moles of nitrogen, you would need 9 moles of hydrogen to react completely.
How many moles of hydrogen gas is required to completely react with chlorine in the following reaction that has a pressure of 735 torr at 34 C in a 450 ml container according to the reaction. H2 Cl2 2?
To find the number of moles of hydrogen gas, we first need to calculate the number of moles of chlorine gas using the ideal gas law formula (PV = nRT). Once we have the moles of chlorine gas, we can determine the moles of hydrogen gas needed for the reaction. In this case, the stoichiometry of the reaction states that 1 mole of chlorine gas reacts with 1 mole of hydrogen gas, so the required moles of hydrogen gas will be equal to the moles of chlorine gas.
