<u>Answer:</u> The correct statements are they are hydrocarbons, they have single bonds, petroleum and natural gas are most likely alkanes  and they are saturated.

<u>Explanation:</u>

Alkanes are defined as the hydrocarbons which contain a single covalent bond between two carbon atoms. The general formula for these hydrocarbons is given as C_nH_{2n}. These are known as saturated hydrocarbons.

Petroleum consists of various linear and branched alkanes and natural gas mainly consists of methane.

Hence, the given statements are given above.

If 21.5 mol of an ideal gas is at 9.65 atm at 10.90 ∘C, what is the volume of the gas?
mamaluj [8]
<h3>Answer:</h3>

51.93 L

<h3>Explanation:</h3>

From the question we are given the following components of an ideal gas;

Number of moles = 21.5 mol

Pressure, P = 9.65 atm

Temperature, T = 10.90°C, but K= °C + 273.15

                         =284.05 k

We are required to calculate the volume of the ideal gas.

We are going to use the ideal gas equation which is given by;

PV = nRT, where P, V, T and n are the pressure, volume, temperature and moles of the ideal gas respectively. R is the ideal gas constant, 0.082057 L.atm/mol.K

To get the volume, we rearrange the formula to get;

V = nRT ÷ P

  = (21.5 × 0.082057 × 284.05 K) ÷ 9.65 atm

  = 51.93 L

Thus, the volume of the ideal gas is 51.93 L

A gas experts a force of 5,610 N over an area of 0.342 m2. What pressure does the gas expert in Pa?​
Snowcat [4.5K]

Answer:

<h2>16,403.5 Pa</h2>

Explanation:

The pressure exerted by the gas can be found by using the formula

p =  \frac{f}{a}  \\

f is the force

a is the area

From the question we have

p =  \frac{5610}{0.342}  \\ 16403.508...

We have the final answer as

<h3>16,403.5 Pa</h3>

Hope this helps you
