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.

When 35.0 mL of 0.400 M hydrobromic acid and 35.0 mL of 0.400 M ammonia are combined, the pH of the resulting solution will be :

Kay [80]

Answer:

B. Equal to 7.

Explanation:

Hydrobromic acid is a strong acid that decreases pH and ammonia is a strong base that increases pH.

As the initial pH of water is 7,0 the addition of 35.0mL of 0.400M HBr will produce a pH less than 7,0. But, the same effect of decreasing pH is reverted for the addition of 35.0mL of 0.400M HNO3.

That means the net effect of the two addition is to have a pH:

B. Equal to 7.

Zinaida [17]

Answer:

<h2>URANIUM </h2>

Explanation:

What is the source of energy in nuclear power plants?

Uranium is the fuel most widely used by nuclear plants for nuclear fission. Uranium is considered a nonrenewable energy source, even though it is a common metal found in rocks worldwide. Nuclear power plants use a certain kind of uranium, referred to as U-235, for fuel because its atoms are easily split apart.

Which metal is more active than H2? (1) Ag (3) Cu (2) Au (4) Pb

astraxan [27]

Answer is (4) - Pb.

According to the reactivity series of elements

- the elements which are above the hydrogen are more reactive than hydrogen.

- the elements which are below the hydrogen are less reactive than hydrogen.

Among the given choices, only Pb is placed above the hydrogen in the reactivity series and rest are below the hydrogen.

Hence, Pb is more active than hydrogen.
