Answer:7.229 grams of oxygen is formed by the complete reaction of 35.23 g of metallic sodium with oxygen at 130–200 °C, a process that generates sodium oxide, which in a separate stage absorbs oxygen: 4 Na + O2 → 2 Na2O. The ozone oxidizes the sodium to form sodium peroxide.
Answer:
The change in enthaply when 10.0 g of nitrogen triiodide decomposes is -3.67 kJ.
Explanation:
Enthalpy of the reaction when 2 moles of nitrogen triiodide decomposed =
Enthalpy of the reaction when 1 moles of nitrogen triiodide decomposed :
Mass of nitrogen triiodide decomposed = 10.0 g
Moles of nitrogen triiodide = 
Change in enthaply when 0.02532 moles of nitrogen triiodide decomposed:
Answer:
Solvent
Explanation:
Many people use the solute to describe the solid being dissolved and the solvent to describe the thing doing the dissolving, but really solvent means the part of the solution with a greater amount/concentration.
For example, if you have 1 gram of salt in 10 liters of water, the water is the solvent.
Answer:
B. The coefficients give the molar ration of the reactants
