Answer:

The volume of 4.92 grams of hydrogen gas at STP is 9.105 litter.

Explanation:

We know that, the molecular weight of hydrogen gas (H_{2} ) = 1\times 2 = 2.

Moles of hydrogen gas = \frac{weight}{molecular weight}  = \frac{4.92}{2} = 2.46 moles.

At STP, 1 mole of hydrogen gas = occupies 22.4 litter

    So, 2.46 mole of hydrogen gas = occupies \frac{22.4}{2.46} = 9.105 litter.

Hence, the volume of 2.46 grams of hydrogen gas at STP is 9.105 litter.

A certain compound was found to have the molecular formula C5H12O2. To which of the following compound classes could the compoun
IgorC [24]

Answer : The given compound belongs to ether and alcohol.

Explanation :

The chemical formula of the given compound is, C_5H_{12}O_2

First we have to calculate the degree of unsaturation.

Formula used:

Degree of unsaturation = \frac{2C+2+N-X-H}{2}

where,

C = number of carbon

H = number of hydrogen

N = number of nitrogen

X = number of halogen

Degree of unsaturation = \frac{2\times 5+2+0-0-12}{2}=0

The degree of unsaturation is, 0 that means there is no double or triple bond in the compound only single bond is present between the atoms.

Thus, the given compound belongs to ether and alcohol.

Hydrocarbons that contain a double or triple bond between carbons are considered unsaturated because
ipn [44]

Answer:

alkenes and alkynes are considered as unsaturated hydrocarbons because they are capable of reacting with hydrogen in the presence of a catalyst to form a saturated hydrocarbon (alkanes)

Explanation:

A saturated compound contains a chain of carbon atoms joined by single bonds, with hydrogen atoms attached to each carbon atom.  

Propane for example, CH₃-CH₂-CH₃.  

It is saturated because all the carbon atoms holds maximum number of hydrogen atoms.  

Alkenes such as Propene (CH₂=CH-CH₃) and alkynes like Propyne,

(CH₃-C≡C-H) are unsaturated because the central carbon atoms contain less number of hydrogen atoms than they possibly could.
