Which statement correctly describes the classification of chemical reactions into different categories?(1 point)
I don't see any statements from which to choose
In a synthesis reaction, two atoms of sodium (Na) combine with one molecule of chlorine gas (Cl2) to produce sodium chloride (NaCl). How many molecules of sodium chloride are produced?(1 point)
2Na + Cl2 ==> 2NaCl
In the decomposition of water, why is twice as much hydrogen as oxygen formed?(1 point)
Because water is H2O; i.e., there is twice as much H as O in H2O.
Which component is transferred between substances in an oxygen-reduction reaction?(1 point)
electrons are transferred
In a chemical reaction, substance A transfers electrons to substance B. Which statement is correct?(1 point) No statements from which to choose

Not all reactions fit into a category, and some reactions can fit into more than one category.
two
There are two atoms of hydrogen and one atom of oxygen in a water molecule.
electrons
Substance B is reduced and acts as the oxidizing agent.
