Nitrogen when combined with oxygen can form various oxides. 3.5g of nitrogen gas is burned in oxygen to form 11.5 g of an oxide of nitrogen. a) Determine the mass of oxygen burned. (HINT: the oxide contains only nitrogen and oxygen) b) Using data from the experiment find the percent of nitrogen by mass in the oxide. I'm stuck on b)! Help! :(

Ase your answer to this question on the information below. hydrocarbons and fissionable nuclei are among the sources used for the production of energy in the united states. a chemical reaction produces much less energy than a nuclear reaction per mole of reactant. the balanced chemical equation below represents the reaction of one molecule of a hydrocarbon with two molecules of oxygen. chemical equation: ch4 + 2o2 → co2 + 2h2o + 1.48 × 10−18 jthe nuclear equation below represents one of the many possible reactions for one fissionable nucleus. in this equation, x represents a missing product. nuclear equation: write an isotopic notation for the missing product represented by x in the nuclear equation.

In which situation can a mixture always be called a solution

When balancing a chemical equation:
