You are given 1.546 grams of a white powder and told that it is a mixture of potassium carbonate and sodium carbonate. you are also asked to determine the percent composition (percent sodium and potassium carbonate) by mass of the sample. to find the percent composition you decide to slowly add the powder to 10.00 ml of 1.15 m nitric acid until the bubbling stops. after adding the powder to the acid you reweigh your sample and its mass is 0.802 g. what is the percent composition by mass of the powder?

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.
