Alkanes represent one family of organic compounds that is composed of carbon and hydrogen.

Alkanes are organic compounds that solely have hydrogen and carbon atoms in single bonds and do not have any additional functional groups. Alkanes can be divided into three groups: cycloalkanes, branched alkanes, and linear straight-chain alkanes.

The general formula for alkanes is CnH2n+2. Alkanes are also saturable hydrocarbons. Cyclic hydrocarbons like cycloalkanes have rings-shaped arrangements of their carbon atoms.

Therefore, Alkanes are an example of an organic chemical family made of carbon and hydrogen.

A bicycle pump contains 250 mL of air at a pressure of 102 kPa. If the pump is
CaHeK987 [17]

Considering the Boyle's law, the new volume becomes 1,148,344.444 mL or 1148.34 L.

<h3>Boyle's law</h3>

Boyle's law relates pressure and volume, stating that the volume occupied by a given mass of gas at constant temperature is inversely proportional to pressure. This means that if the pressure increases, the volume decreases, while if the pressure decreases, the volume increases.

Boyle's law is expressed mathematically as:

P×V=k

Now it is possible to assume that you have a certain volume of gas V1 which is at a pressure P1 at the beginning of the experiment. If you vary the volume of gas to a new value V2, then the pressure will change to P2, and the following is true:

P1×V1=P2×V2

<h3>New volume</h3>

In this case, you know:

  • P1= 102 kPa= 10335.1 atm (being 1 kPa= 101.325 atm)
  • V1= 250 mL
  • P2= 2.25 atm
  • V2= ?

Replacing in the Boyle's law:

10335.1 atm ×250 mL= 2.25 atm×V2

Solving:

(10335.1 atm ×250 mL)÷ 2.25 atm= V2

<u><em>1,148,344.444 mL= 1148.34 L=  V2</em></u>

Finally, the new volume becomes 1,148,344.444 mL or 1148.34 L.

faust18 [17]

Answer:

the carbon atoms in the double bond cannot rotate

Explanation:

Isomers refer to molecules that have a distinct arrangement of the atoms in the molecule but have the same molecular formula.

Alkenes refer to a series of unsaturated hydrocarbons that contain ethylene and propylene.

Some alkenes have geometric (cis-trans) isomers because <u>the carbon atoms in the double bond cannot rotate</u>.

HACTEHA [7]

Answer:

(a) Iron is being oxidized.

(d) Sulfur is being reduced.

Explanation:

Let's consider the following redox reaction.

8 Fe(s) + S₈(s) → 8 FeS(s)

Iron is being oxidized according to the following oxidation half-reaction:

Fe(s) → Fe²⁺(s) + 2 e⁻

Sulfur is being reduced according to the following reduction half-reaction:

S₈(s) + 16 e⁻ → 8 S²⁻(s)
