4. If 52.0 g of magnesium react with excess hydrochloric acid, how many liters of hydrogen gas can be made at 300 K and 0.970 atm?

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.

What is the empirical formula of c6h18o3? ch3o c2h5o c2h6o c2h5o5

Atoms contain subatomic particles called protons and neutrons. when these protons and neutrons spilt, a lot of energy is released
