Name the following structure
Paraphin [41]

Answer:

2–butyne.

Explanation:

To name the compound given above, we must determine the following:

1. Determine the functional group of the compound.

2. Determine the longest continuous carbon chain. This gives the parent name of the compound.

3. Locate the position of the functional group by giving it the lowest possible count.

4. Combine the above to obtain the name.

Thus, we shall name the compound as follow:

1. The compound contains triple bond (C≡C). Therefore, the compound is an alkyne.

2. The longest chain is carbon 4. Thus the parent is butyne.

3. The triple bond (C≡C) is located at carbon 2 when we count from either side.

4. The name of the compound is:

2–butyne

A sample of 0.200 moles of nitrogen occupies 0.400 L. Under the same conditions, what number of moles occupies 1.200 L
IRISSAK [1]

The number of mole of nitrogen that occupies 1.2 L under the same condition is 0.6 mole

<h3>Data obtained from the question </h3>
  • Initial mole (n₁) = 0.2 mole
  • Initial volume (V₁) = 0.4 L
  • Final volume (V₂) = 1.2 L
  • Final mole (n₂) =?

<h3>How to determine the final mole </h3>

The final mole can be obtained by using the ideal gas equation as illustrated below:

PV = nRT

Divide both side n

PV / n = RT

Divide both side by P

V / n = RT / P

RT / P = constant

V / n = constant

Thus,

V₁ / n₁ = V₂ / n₂

0.4 / 0.2 = 1.2 / n₂

2 = 1.2 / n₂

Cross multiply

2 × n₂ = 1.2

Divide both side by 2

n₂ = 1.2 / 2

n₂ = 0.6 mole

Calculate each of the following:<br> (a) Mass fraction of Cl in calcium chlorate
Marianna [84]

Mass fraction has been the mass of an individual element with respect to the compound. The mass fraction of chloride in calcium chlorate is 0.171.

<h3>What is meant by a mass fraction?</h3>

Mass fraction has been defined as the ratio of the masses of the individual elements present in a compound to the total mass of the molecule or compound.

The formula for a mass fraction (w) is given as,

Mass fraction (w) = mass ÷ total mass

Given,

Mass of chlorine = 35.453 grams per mole

The molar mass of calcium chlorate (Ca(ClO₃)₂) = 206.98 grams per mole

Substituting and solving the values above as

w = mass of chlorine ÷ total mass of calcium chlorate

w = 35.453 ÷ 206.98

w = 0.171

Therefore, the mass fraction of Cl in calcium chlorate is 0.171.
