<span>The correct answer is option 1. It is the carbon (C) atom that can bond with each other to form ring and chain structures in compounds. These ring and chain structures and compounds are called organic compounds. Chain structures include alkanes, alkenes, alkynes. Ring structures include cyclic hydrocarbons and aromatic hydrocarbons.</span>

Answer: Option (1) is the correct answer.

Explanation:

Carbon atoms are able to combine with its atoms resulting in formation of long chains. This property of carbon is known as catenation. Whereas carbon atom also has the property to combine with other atoms and results in the formation of long chains or rings.

On the other hand, oxygen, nitrogen, and fluorine does not form long chains or rings.

Thus, we can conclude that carbon is the element whose atoms can bond with each other to form long chains or rings.

Which one is unsaturated hydrocarbon?

Fittoniya [83]

Answer:

The correct answer is - D C2H4.

Explanation:

Saturated hydrocarbons are hydrocarbons with single covalent C-C bonds. They are known as alkanes. The general formula for these hydrocarbons is CnH2n+2

Unsaturated hydrocarbons the hydrocarbons with double or triple covalent C-C bonds. They are known as alkenes and alkynes respectively. The general formula for these hydrocarbons is CnH2n and CnHn-2

For the given options:

Option D: C2H4, is the simplest alkene with a double bond so it is an unsaturated hydrocarbon.

Consider the formation of hcn by the reaction of nacn (sodium cyanide) with an acid such as h2so4 (sulfuric acid): 2nacn(s)+h2so

Artemon [7]

2NaCN(s) + H₂SO₄(aq) --> Na₂SO₄(aq) + 2HCN(g)

The molar ratio between NaCN : HCN is 2:2 or 1:1

Mass of HCN = 16.7 g

Molar mass of HCN = 1 + 12 + 14 = 27 g/mol

Molar mass of NaCN = 49 g/mol

Therefore, the mass of NaCN is

16.7 g of HCN x 49 g/mol of NaCN / 27 g/mol of HCN = 30.3 grams of NaCN

Therefore, 30.3 grams of NaCN gives the lethal dose in the room.

Describe the relationship between volume and temperature of an ideal gas

kvv77 [185]

Answer:

Explanation:

Here, we want to describe the relationship between the volume and temperature of an ideal gas

This relationship is defined by Charles' law

From this law, we know that the volume of a given mass of gas is directly proportional to its temperature at a fixed pressure

What this means is that as long as the pressure remains unchanged, when the volume increases, the temperature increases, and when the volume decreases, the temperature decreases

These can be represented by the mathematical formula below:

$\frac{V_1}{T_1}\text{ = }\frac{V_2}{T_2}$
