Answer:

1. The air boiled out of water as steam is rich in water vapor, H₂O(g)

2. Benzene reacts with hydrogen in the presence of nickel catalyst at 180°C to give cyclohexane.

Explanation:

1. When water boils liquid water passes to gaseous phase.

Water in gaseous phase is named water vapor or steam.

This happens around 100ºC, depending on the atmospheric pressure.

The air that is around the boiling water will carry that steam, becomind an air rich in water vapor, H₂O(g)

2. Benzene has chemical formula C₆H₆.

It is a cyclic unsaturated hydrocarbon. Benzene contains 3 double bonds.

When unsaturated hydrocarbons are heated in the presence of nickel catalyst, the double bonds are broken, forming single bonds and adding the needed hydrogen to the chain: one to each carbon that had a double bond transformed into single bond.

Thus, the product of the catalytic hydrogenation of benzene, C₆H₆, is cyclohexane, C₆H₁₂

if the spin of one electron in an orbital is clockwise , what is the spin of the other electron in that orbital

nata0808 [166]

Here we have to get the spin of the other electron present in a orbital which already have an electron which has clockwise spin.

The electron will have anti-clockwise notation.

We know from the Pauli exclusion principle, no two electrons in an atom can have all the four quantum numbers i.e. principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (m) and spin quantum number (s) same. The importance of the principle also restrict the possible number of electrons may be present in a particular orbital.

Let assume for an 1s orbital the possible values of four quantum numbers are n = 1, l = 0, m = 0 and s = $\frac{+}{-}$ $\frac{1}{2}$ .

The exclusion principle at once tells us that there may be only two unique sets of these quantum numbers:

1, 0, 0, + $\frac{1}{2}$ and 1, 0, 0, - $\frac{1}{2}$ .

Thus if one electron in an orbital has clockwise spin the other electron will must be have anti-clockwise spin.

1st Define Covalent bond and it's type

irakobra [83]

Answer:

COVELENT BOND:-The chemical bond formed by the sharing of an electron pair between two atoms so that both the atoms get their octet complete is called covalent bond

SINGLE COVELENT BOND:-it is formed by sharing of one pair of electron between two atoms
DOUBLE COVELENT BOND:-it is formed by sharing of two pair of electron between two atoms
TRIPLE COVELENT BOND:- it us formed by sharing of three pair of electron beyween two atoms

2)Electron dot structures of carbon dioxide:-Oxygen atom contains 6 valence electrons which form 2 lone pairs. Since it is bonded to only one carbon atom, it must form a double bond. Carbon atom contains four valence electrons, resulting in zero lone pairs. Therefore, it is doubly bonded to each oxygen atom.

3))Sulfur has an atomic number is 16 with the

symbol as 'S'

The electronic configuration of sulfur is said to be 2,8,6
The valence electrons present in sulfur is 6.
Sulfur forms an octet structure by connecting 8 sulfur atoms with each other by the formation of single covalent bonds.
The sulfur molecule's chemical formula is S8.
Sulfur is usually used in the manufacture of sulphuric acid.
