Answer:

Copper is a reddish-brown metal that is easily stretched to make wires. These characteristics are examples of Dhybral (physical/chemical) properties of copper.

Explanation:

When copper metal is heated in concentrated nitric acid, the copper dissolves to form a deep blue solution, and a brown gas is released from the acid.

Answer:

Here's what I get.

Explanation:

According to Markovnikov's rule, the H will add to a terminal carbon, generating three resonance stabilized carbocations.

The Br⁻ ion will add to any of the three carbocations.

There are three possible products:

  1. 5-bromo-2,5-dimethylhexa-1,3-triene (1)
  2. 3-bromo-2,5-dimethylhexa-1,4-triene (<em>2</em>)

Students experiment with the flow of
OleMash [197]
Rubber is not very good at conducting electricity. This is because rubber makes it difficult for electrons to flow between atoms, due to rubber having tightly packed electrons. Materials like rubber are known as insulators.
Conductors are the opposite, they conduct electricity very well. Examples of conductors are metal, which is why metal is used in wires.
Since rubber is not a conductor, answer choice B can be eliminated. This can also eliminate answer choice D, since insulators like rubber don't allow electricity to easily flow.
While rubber gloves keep our hands dry, there are no liquids involved in this experiment and this is not the main reason for using rubber gloves. This eliminates answer choice C.

The answer is A. rubber gloves are insulators.
The teacher instructs the students to wear rubber gloves to prevent them from getting an electric shock.

Answer:
A. rubber gloves are insulators

Hope this helps!
