hybridization is defined as mixing up of the atomic orbital with nearly same energies according to linear combination of atomic orbitals. the orbitals formed are equal in energy and are called hybrid orbitals .

Explanation:
Mol is the amount of molecules in something. Mol are similar to donuts, if you have a dozen of something you have 12 of them. If you have a mol of Hydrogen gas you 6.02•10^23 molecules of Hydrogen gas. If you are taking a chemistry class you will probably receive questions involving converting grams to mol and vice versa.
Converting Grams to Mol:
grams of x•(1/molecular mass of x)
note: you can find molecular mass of x by looking at the masses of the elements you need to add up in the periodic table
Converting Mol to Grams:
mol of x•(molecular mass of x)
For the answer to the question above, <span>those that apply are: </span>
<span>- salt is not chemically bonded to water </span>
<span>- the ratio of salt to water may vary </span>
<span>- salt and water retain their own chemical properties

Answer:
Explanation:
An element whose atomic number is 68 (number Z), has 68 electrons and 68 protons. According to the periodic table it corresponds to the element Erbium (Er), whose mass number (A) is 167. The number of neutrons is 167-68 = 99.
For every two molecules of water formed, one hydrogen atom is needed.
Answer: Option C.
<u>Explanation:</u>
The water particle is very simple and basic. A particle is a bit of issue that contains at least two iotas. The logical name for water is H2O. It is called H2O since it has two iotas of hydrogen (H) and one molecule of oxygen (O). There are a great many these atoms in a single drop of water.
A water molecule is formed when two atoms of hydrogen bond covalently with an atom of oxygen.
