Chemistry
1 answer:
valkas [14]3 years ago

C.) a substance with a low ability to conduct energy

Explanation:

The statement that best defines insulators is that it is a substance that has low ability to conduct energy.

Insulators resist the movement of mostly electrical and thermal energy.

They have unique properties that makes them so.

  • Insulators are substances that do not conduct heat and electricity.
  • Both their solid and molten form lacks the capability of electrical and thermal conduction.
  • Some substances can only conduct when molten or liquid.
  • Conductors are materials that allows for the passage of electrical and heat energy.
  • Most conductors are usually salts, ionic compounds and metals.
  • Non-conductors like insulators are usually plastics and woods.

What types of elements- metals,
crimeas [40]

Answer:

Noble gases

Explanation:

The noble gases are non-metals that requires the highest amount of energy to remove an electron from their shells.

The reason for this difficult is that their electronic configuration confers a stable configuration them.

  • The ionization energy is the energy required to remove the most loosely held electrons in an atom.
  • Due to the special stability of noble gases, it is very difficult to remove electrons from an atom of noble gases.

Calcium reacts with Hydrochloric acid to produce Calcium chloride and
hammer [34]

Answer:

Mass = 2.77 g

Explanation:

Given data:

Mass of HCl = 2 g

Mass of CaCl₂ produced = ?

Solution:

Chemical equation:

2HCl + Ca    →     CaCl₂ + H₂

Number of moles of HCl:

Number of moles = mass / molar mass

Number of moles = 2 g/ 36.5 g/mol

Number of moles = 0.05 mol

now we will compare the moles of HCl with CaCl₂.

                   HCl       :         CaCl₂

                     2         :          1

                   0.05     :       1/2×0.05 = 0.025 mol

Mass of CaCl₂:

Mass = number of moles × molar mass

Mass = 0.025 mol × 110.98 g/mol

Mass = 2.77 g
