Answer:

C) 0.457

Explanation:

The ratio between O2 and H2O is 1:2 according to the balanced equation. You can find how many moles is O2 by : 5.12/22.4 = 0.22857 ( 1 mole = 22.4 litters)

Moles of H2O will be 0.22857 * 2 = 0.457142.

The shape of the sulfur dioxide molecule, where sulfur is the central atom is
fgiga [73]

Answer:

bent

Explanation:

The molecular formula of sulfur dioxide is written as SO₂

The molecular geometry of sulfur dioxide can be determined using the Lewis structure.

The Lewis structure shows the distribution of electrons around the atoms of a given compound such as sulfur dioxide (SO₂).

In this compound, sulfur is the central atom with 6 valence electrons.

The sulfur is bonded covalently with two oxygen atoms, each with 6 valence electrons. Oxygen contributes 2 lone pairs while sulfur which is the central atom contributes 1 lone pair of electrons in the bond.

The bond angle between the two oxygen atoms and the central sulfur atom is approximately 120⁰, as a result of the bent shape of the molecular structure.

Label the slightly negative and slightly positive parts of the water molecule. Use this illustration to explain polarity.
Daniel [21]
The water molecule is a polar molecule which would mean that there is an uneven distribution of charges. Each molecule of water has partial positive and partial negative end.  The partial positive charges is found in the H atoms while the partial negative is at the O atom. This is due to the the unequal sharing of the electrons.
