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.

For the reaction below, initially the partial pressure of all 3 gases is 1.0atm. . 2NH3(g)--> N2(g) + 3H2(g) K, 0.83 1. When
erma4kov [3.2K]

Answer:

The reaction would shift toward the reactants

When the reaction reach equilibrium the partial pressure of NH3 will be greater than 1atm

Explanation:

For the reaction:

2NH₃(g) ⇄ N₂(g) + 3H₂(g)

Where K is defined as:

K = \frac{P_{N_{2}}*P_{H_2}^3}{P_{NH_3}^2} = 0.83

As initial pressures of all 3 gases is 1.0atm, reaction quotient, Q, is:

Q = \frac{1atm*{1atm}^3}{1atm^2} = 1

As Q > K, <em>the reaction will produce more NH₃ until Q = K consuming N₂ and H₂.</em>

Thus, there are true:

<h3>The reaction would shift toward the reactants</h3><h3>When the reaction reach equilibrium the partial pressure of NH3 will be greater than 1atm</h3>

What is the significance of enzymes in maintaining homeostasis in living organisms ?
GalinKa [24]
 Enzymes are needed for metabolic pathways in the body, respiration, digestion and other important life processes. When enzymes function properly, homeostasis is maintained. However, if an enzyme is lacking or has an incorrect shape due to genetic mutation, this can lead to disease within an organism.
