Stoichiometry Questions & Answers


What mass of NO2 is formed when NO reacts with 386 g of O2?  Reference: Nitrogen combines with oxygen in the atmosphere during lightning flashes to form nitrogen monoxide, NO, which then...
The correct answer to this question is 1110 g NO2. To solve this question, one must first create an equation. Each side of the equation must have the same number of the atom's moles. This will allow the equation to be balanced. From there, we must f
What is the mass (in grams) of carbon required to react with water to form 1.00 mol CH4(reaction given below)? Coal can be converted to methane gas by a process called coal gasification. The...
The correct answer is option B From the equation: 2C(s) + H2O (l) (CH4 (g) + CO2 (g) We can tell that 2 moles of carbon are required to react with water to form 1.00mol CH4. 12 grams of carbon is equal to 1 mole. Since we have two moles Total amount
How many moles of O2 will be produced if 5 moles of the disinfectant hydrogen peroxide H2O2 decomposes?
The answer is 2.5 mol H2O2. It is through decomposition that the old elements are usually broken down into new pieces that can still be useful for the environment. It should also be a balanced equation where no elements are removed nor added. 2
How many grams of NaCl are produced when 80.0g of O2 are produced in the following reaction?
The correct answer to this question is A, 576.00g oxygen b. 97.4g NaCl. This question would be found on a chemistry test, focused on stoichiometry. This subset of chemistry is the calculation of the products and reactants in chemical reactions. Stoic
