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.

1. Which statement correctly describes the classification of chemical reactions into different categories?

-Not all reactions fit into a category, and some reactions can fit into more than one category.

2. 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?

-Two

3. In the decomposition of water, why is twice as much hydrogen as oxygen formed?

- There are two atoms of hydrogen and one atom of oxygen in a water molecule.

4. Which component is transferred between substances in an oxygen-reduction reaction?

-Electrons

5. In a chemical reaction, substance A transfers electrons to substance B. Which statement is correct?

-Substance B is reduced and acts as the oxidizing agent.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
