Answer:

Insulator

Explanation:

An insulator does not conduct electricity. Insulators offer high resistance to the free flow of electron. Rubber is a good insulator.  

A conductor conducts electricity. Metals are good conductors of electricity. Metals have free flowing electrons that allow them to conduct electricity.  As metals conduct electricity they have a distribution of charge on its surface.

We saw in the calorimeter experiment that the combustion of a fuel is exothermic. what can you then say about the formation of a
ankoles [38]

Answer:

This question appear incomplete

Explanation:

This question appear incomplete. However, fuel is formed through a natural phenomenon involving the conversion of large amount dead and decayed organisms (usually algae and zooplanktons) to combustible fuel through exposure to relatively high temperature and pressure (over millions of years) in the earth's crust. Thus, since this involves a sort of absorption of heat energy (from the earth's crust), it can be referred to be an endothermic reaction.

Find the molar mass of this
kirill115 [55]

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
