List two factors that would help you decide which hydrocarbon fuel to use in a particular application

Chemistry
1 answer:
OverLord2011 [107]3 years ago
8 0

The answer is;

  1. Melting and boiling points
  2. Unit energy output

These properties are dependent on the chemical composition of the varying hydrocarbons. Coal is a hydrocarbon used in some applications due to its solid nature at room temperatures. The branching of hydrocarbon (cyclic or chain) also determines the energy output on combustion. Gasoline burns more energy than paraffin

What statement does not accurately describe the following equation? C6H12O6+--->6H20+6CO2+energy A) oxygen is a react ant B)
STatiana [176]
The answer is B. The complete equation is C6H12O6 + 6O2 -->6H2O + 6CO2 + energy. So we can know that A and C and D is right. For B, the reaction release energy so it is exothermic reaction.

A solution is 40 cetic acid by mass. the density of this solution is 1.049 g/ml. Calculate the mass of pure acetic acid in 220 m
taurus [48]

The mass of pure acetic acid in 220 ml of the given solution at 20°C is 92.311 g

<h3>What is Acetic acid?</h3>

Acetic acid is a type of carboxylic acid and also known as ethanoic acid

Its formula is CH₃COOH.

It is an organic compound and is a colorless liquid

It is mostly used in the production of vinegar

40 % acetic acid by mass means,

40 g of acetic acid is dissolved in 100 g of solution.

The density of solution at 20°C,

\rho = 1.049 g/ml

We know,

\rho = \frac{m}{V}

V = \frac{m}{\rho}

The volume of the solution, V = \frac{100}{1.049} = 95.33 ml

95.33 ml of solution contains 40 g of pure Acetic acid

220 ml of solution contains\frac{40 \times 220}{95.33} = 92.311 g of pure Acetic acid

Thus, the mass of pure Acetic acid in 220 ml of solution at 20°C is 92.311 g
