Reactive oxygen species (ros) are unstable oxygen-containing molecules that can cause damage to enzymes and membranes. cells can defend against damage by converting these ros to harmless species. complete the following reactions by replacing the question mark with the appropriate formula. choose the correct enzyme or enzyme class.2 o_2_ + 2h+ > ? + o_2_ (what are the two + 2 gsh > 2 h_2_o + gs-sh (what are the two ? )

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 pqr m< p=60 m< q= 30 and m

The number of moles of a given mass of a substance can be found without knowing its molecular formula or molar mass. true false
