Covalent bonds keep the hydrogen and oxygen atoms together

Answer:

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.

Question 1 (Multiple Choice Worth 2 points)
Nookie1986 [14]

The scientific models are used because they allow scientists to make predictions and make it easier for scientists to avoid using data. option A and C is correct.

<h3>What are scientific models?</h3>

The scientific models are those which is given by scientists to allow them to make prediction about anything particular on which they are working or making research for it some examples are plum pudding model for an atom and bohr's model of an atom etc.

The biggest advantage is that scientists do not have to check the given data which are written into books they can perform their experiment and can conclude the data by performing experiment.

Therefore, scientific models are used because they allow scientists to make predictions and make it easier for scientists to avoid using data. option A and C is correct.

What is the difference between a polar and a nonpolar bond?And how can i figure out if its polar or nonpolar in a bond question?
ra1l [238]

Answer:

If the electronegativity of two atoms is basically the same, a nonpolar covalent bond will form, and if the electronegativity is slightly different, a polar covalent bond will form.

Explanation:

that's your answer very easy.

According to the law of conservation of mass, the mass of reactants will be equal to the mass of the products. The mass of products and reactants will only differ during a nuckear reaction
Changing of the physical state of water is not a nuclear reaction. So becoz of that the mass will remain constant without any change.
