b. Equation for the reaction is given below;

4HCl + 2F₂ ----> 4HF + 2Cl₂

c. The reaction is single replacement reaction such that fluorine gas molecules replace the chlorine atoms in hydrogen chloride to form hydrogen fluoride with the liberation of chlorine atoms as gaseous molecules.

Methanol, propan-1-ol and ethanol has boiling point of 65 degree celsius, 97 degree celsuis, 87 degree celsuis respectively. A student uses fractional distillation to separate a mixture of these compound. State which liquid will be collected in the second fraction and explain why

Answers

Answer:

ethanol

Explanation:

Methanol has a boiling point of 65°C, propan-1-ol has a boiling point of 97°C and ethanol has a boiling point of 87°C

Fractional distillation is used for separating miscible liquids through the use of the different vapor pressure properties of the liquids. As the mixture is heated up, components start to vaporize according to their boiling points. The component with the least boiling point vaporizes first while the component with the highest boiling point vaporizes last.

This means that methanol would vaporize at the first fraction because it has the lowest boiling point followed by ethanol at the second fraction and then propan-1-ol at the last fraction.

What are aromatic hydrocarbons ?

Hydrocarbons with delocalized pi electrons and sigma bonds between their carbon atoms are known as aromatic hydrocarbons. One example is benzene. Since they smell, they are said to as aromatic.

One aromatic ring makes up monocyclic aromatic hydrocarbons (MAHs). The well-known environmental contaminants benzene, toluene, ethylbenzene, and xylenes are among the most combustible and water-soluble aromatic hydrocarbons (BTEX).

The typical aromatic parent structure is benzene. When the benzene ring is a substituent, it is referred to as a phenyl group.

Thus, Pain relievers are make up of aromatic hydrocarbons, option C is correct.

Further explanation  

Equalization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:  

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.  2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product  3. Select the coefficient of the substance with the most complex chemical formula equal to 1

A. Chemical energy - Sound energy - Electrical energy


O B. Electrical energy - Chemical energy - Sound energy


C. Chemical energy - Electrical energy - Sound energy


O D. Sound energy - Electrical energy - Chemical energy

Answers

Answer:

C. Chemical energy - Electrical energy - Sound energy

Explanation:

According to the law of conservation of energy, energy can be transformed i.e changed from one form to another. According to this question, a student builds an electrical circuit, which connects a battery to a siren. Based on this description, the electrical circuit uses ELECTRICAL ENERGY supplied by the CHEMICAL ENERGY in the battery cell.

The electrical energy in the circuit connects the CHEMICAL ENERGY in the battery to the siren, which makes the sound using SOUND ENERGY. In other words, the CHEMICAL ENERGY of the battery powers the ELECTRICAL ENERGY of the circuit to make SOUND ENERGY in the siren. Hence, the order of energy transformation is: Chemical energy - Electrical energy - Sound energy

Answer:

C. Chemical energy - Electrical energy - Sound energy

find the molar mass of this

Answers

Explanation:

Given problem:

Find the molar mass of:

  SO₃ and C₁₀H₈

Solution:

The molar mass of a compound is the mass in grams of one mole of the substance.

To solve this, we are going to add the individual atomic masses of the elements in the compound;

  Atomic mass;

       S = 32g/mol; O = 16g/mol; C = 12g/mol and H = 1g/mol

For  SO₃;

     = 32 + 3(16)

     = 32 + 48

     = 80g/mol

For C₁₀H₈

      = 10(12) + 8(1)

      = 120 + 8

       = 128g/mol
