4NH3 + 6NO -> 5N2 + 6H2O
145 g N2 x (1 mol/28.0 g) x (6 mol NO/5 mol N2) x (30.0 g NO/1 mol NO) = 186.4285714 g NO
rounds to 186 g NO due to significant figures
10,225 g oxygen are required.
800 g oxygen are needed.
hi you cant produce zrb2 by mixing these salt lonely at elevatedtemprature if you want extra inforamtion for producing ZrB2 feel free to emial me at mm.velashjerdi@gmail.com have goodtime
For the reaction 2H₂ + O₂ → 2H₂O, we know that the molar ratio of H₂ to O₂ is 2:1. To produce 900 grams of water, we need 450 grams of hydrogen (900g / 2). Therefore, we need to add 450 grams of hydrogen to 800 grams of oxygen to produce 900 grams of water.
You need 0,9 glucose.
10,225 g oxygen are required.
You would need 5.7 grams of mercury II oxide to produce 1.56 L of oxygen gas according to the following reaction at those conditions.
To find the total mass of CaO that reacts with 88 grams of CO2 to produce 200 grams of CaCO3, we first need to calculate the molar mass of CaCO3 and CO2, then determine the moles of each reactant involved in the reaction. Finally, we use the stoichiometry of the reaction to find the mass of CaO required to react completely with 88 grams of CO2.
800 g oxygen are needed.

In the process of photosynthesis, the overall reaction involves 6 molecules of CO2 producing 1 molecule of glucose. The molar mass of CO2 is 44 g/mol and the molar mass of glucose is 180 g/mol. To produce 180 grams of glucose, you would need 6 * 44 = 264 grams of CO2.
For the reaction 2H₂ + O₂ → 2H₂O, we know that the molar ratio of H₂ to O₂ is 2:1. To produce 900 grams of water, we need 450 grams of hydrogen (900g / 2). Therefore, we need to add 450 grams of hydrogen to 800 grams of oxygen to produce 900 grams of water.
To produce 4 grams of table salt (NaCl), you would need 2 moles of Na and 1 mole of Cl2. This corresponds to 46 grams of Na and 71 grams of Cl2. This would total 117 grams of reactants (2Na + Cl2) to produce 4 grams of NaCl.
To find the amount of Cr2O3 required to produce 83.4 grams of Cr2S3, you should start by determining the molar ratio between Cr2O3 and Cr2S3. This ratio is 2:1. Next, calculate the molar mass of Cr2S3, which is 480.32 g/mol. Using the molar ratio and molar masses, you can find that you need 160.11 grams of Cr2O3 to produce 83.4 grams of Cr2S3.
To find out the grams of lithium nitrate needed, you need to calculate the molar mass of lithium sulfate (Li2SO4) and lithium nitrate (LiNO3). Then use stoichiometry to determine the amount of lithium nitrate required to produce 250 grams of lithium sulfate. The balanced chemical equation for the reaction would also be needed.
To determine the amount of calcium needed, you need to balance the chemical equation for the reaction between calcium and water. The equation is Ca + 2H2O → Ca(OH)2 + H2. Then, convert the mass of water to moles, use the stoichiometry of the balanced equation to find the moles of calcium required, and convert that to grams of calcium.
