What carbon atoms can bond with

1 answer:

8 0

Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds. When it bonds only with hydrogen, it formscompounds called hydrocarbons. Carbon can form single, double, or triple covalent bonds with other carbon atoms.

The correct answer is option c, that is, nucleus.

A usual atom comprises three subatomic particles, that is, the neutrons, protons, and electrons. According to Bohr's model, the majority of the mass of an atom is in the nucleus, that is, a small, dense region at the center of each atom, comprising nucleons.

The nucleons incorporate neutrons and protons. All the positive charge of an atom is found in the nucleus and arises from the protons, the neutrons are neutrally-charged, and the electrons are the negatively charged particles found outside of the nucleus.

A 15.75 g piece of iron absorbs 1097 joules of heat energy, and its temperature changes from 25°C to 177°C. Calculate the specif

vekshin1

The answer for the following problem is mentioned below.

Explanation:

Given:

mass of iron (m) = 15.75 grams

heat (q) = 1097 J

initial temperature ( $t_{1}$ ) = 25°C

final temperature ( $t_{2}$ ) = 177°C

To find:

specific heat (c)

We know;

c = q ÷ mΔT

where;

c represents the specific heat

q represents the heat

m represents the mass

t represents the temperature

c = $\frac{1097}{15.75 * (177-25)}$

c = 0.45 J/kg°C

<u><em>Therefore the specific heat capacity of iron is 0.45 J/kg°C.</em></u>

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.
