Hydrogen and oxygen react to form water. At an atomic level, how do we know that a chemical reaction has occurred? *
1 point
Hydrogen molecules are negative, and oxygen positive.
For every oxygen atom, two hydrogen atoms are needed.
The hydrogen and oxygen atoms regroup into a new molecule.
Oxygen atoms are much larger than hydrogen atoms.

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.
