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.

Answer:
1.18 moles of CS₂ are produced by the reaction.
Explanation:
We present the reaction:
5C + 2SO₂ → CS₂ + 4CO
5 moles of carbon react to 2 moles of sulfur dioxide in order to produce 1 mol of carbon disulfide and 4 moles of carbon monoxide.
As we do not have data from the SO₂, we assume this as the excess reagent. We convert the mass of carbon to moles:
70.8 g / 12 g/mol = 5.9 moles
Ratio is 5:1, so 5 moles of carbon react to produce 1 mol of CS₂
Then, 5.9 moles will produce (5.9 . 1) / 5 = 1.18 moles
A. Chemical energy can be in many forms including in the chemicals found in food
<u>Answer:</u> The net ionic equation is written below.
<u>Explanation:</u>
Net ionic equation of any reaction does not include any spectator ions.
Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.
The chemical equation for the reaction of calcium iodide and chromium (III) sulfate is given as:
Ionic form of the above equation follows:
As, chromium and iodide ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.
The net ionic equation for the above reaction follows:
Hence, the net ionic equation is written above.
