In the decomposition of water, why is twice as much hydrogen as oxygen formed?(1 point)
Hydrogen gas has two atoms, and oxygen gas has one atom.
Some oxygen gas escapes the reaction, and hydrogen gas is conserved.
There are two atoms of hydrogen and one atom of oxygen in a water molecule.
Hydrogen atoms are twice the size of oxygen atoms.
The correct answer is: There are two atoms of hydrogen and one atom of oxygen in a water molecule.
Which component is transferred between substances in an oxygen-reduction reaction?(1 point)
The correct answer is: electrons.
In a chemical reaction, substance A transfers electrons to substance B. Which statement is correct?(1 point)
Substance B is oxidized and acts as the reducing agent.
Substance B is reduced and acts as the oxidizing agent.
Substance A is reduced and acts as the reducing agent.
Substance A is oxidized and acts as the oxidizing agent.
The correct answer is: Substance A is oxidized and acts as the reducing agent.
The correct answer is: There are two atoms of hydrogen and one atom of oxygen in a water molecule.
The correct answer is:
There are two atoms of hydrogen and one atom of oxygen in a water molecule.
