7.00 grams of manganese (oxide are completely reacted with a M solution of hydrochloric acid. How many m ^ 2 are needed?

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.

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

Imagine that you push on a large rock. at what point does your effort change the rock’s mechanical energy?
