Water, h2o, is a molecule made of oxygen and hydrogen. the bonds that hold water molecules together are due to shared electrons, and known as bonds. a)covalent)dependent)ionic eliminated)nuclear

a) covalent

Explanation:

Atoms tend to gain, lose or share electrons to be more stable. Most atoms follow the octet rule, which states that atoms tend to complete its valence shell (last level of electrons) with 8 electrons. Oxygen follows this rule, but Hydrogen becomes stable when it has 2 electrons in its valence shell. H and O are non-metals, and they tend to share electrons to complete their valence shell.

Oxygen has 6 electrons in its last level, so it needs 2 electrons to complete its octet. Hydrogen has 1 electron so it needs 1 electron to complete its duet.

As a result, 1 atom of oxygen shares electrons with 2 atoms of hydrogen. This can be represented by a Lewis Structure (attached), where electrons are represented as points around each atom. Covalent bonds are formed by the pair of electrons shared between each pair of atoms. Therefore, in the molecule of water there are 2 covalent bonds.

The answer to the question: choose the correct statement.  a) when ethane reacts with fluorine gas the product is less stable.b) addition reactions of unsaturated hydrocarbons and halogens requires a high activation energy.  c)the double covalent bond within unsaturated hydrocarbons requires a lot of energy to break.  d)the double covalent bond within unsaturated hydrocarbons can be broken easily.is: a) when ethane reacts with fluorine gas the product is less stable.
