Answer: Option (d) is the correct answer.

Explanation:

A fatty acid is defined as a long chain of hydrocarbons that consists of a carboxylic group, that is, COOH group at the end of the chain.

General formula of a fatty acid is $R-(CH_{2})_{n}-COOH$ where n is mostly an even number in many cases.

Fatty acids are also known as aliphatic monocarboxylic acid.

For example, $C_{17}H_{35}COOH$ is the formula of stearic acid which is a fatty acid.

Thus, we can conclude that a long chain of hydrocarbon bonded to cooh is a fatty acid.

What are the units of molality? A. mol/kg B. g/mol C. mol/L D. kg/mol

Serhud [2]

Answer: A.mol/kg

The SI (international system) unit for molality is mol / kg, or solute moles per kg of peptides. A solution with a molality of 1 mol / kg is often described as "1 molal" or "1 m".

How many liters of CO2 gas can be produced at 30.0 °C and 1.50 atm from the reaction of 5.00 mol of C3H8 and an excess of O2 acc

lbvjy [14]

Answer:

249 L

Explanation:

Step 1: Write the balanced equation

C₃H₈(g) + 5 O₂(g) → 3 CO₂(g) + 4 H₂O(g)

Step 2: Calculate the moles of CO₂ produced from 5.00 moles of C₃H₈

The molar ratio of C₃H₈ to CO₂ is 1:3. The moles of CO₂ produced are 3/1 × 5.00 mol = 15.0 mol

Step 3: Convert "30.0°C" to Kelvin

We will use the following expression.

K = °C + 273.15

K = 30.0°C + 273.15 = 303.2 K

Step 4: Calculate the volume of carbon dioxide

We will use the ideal gas equation.

P × V = n × R × T

V = n × R × T/P

V = 15.0 mol × 0.0821 atm.L/mol.K × 303.2 K/1.50 atm

V = 249 L
