Answer:
1. CO₃⁻² + H₂O ⇄ HCO₃⁻ + OH⁻
2. HCO₃⁻ + H₂O ⇄ H₂CO₃ + OH⁻
3. H₂CO₃ → H₂O + CO₂
Basic solution
Explanation:
Brønsted Lowry theory:
Acid → Release a proton
Base → Accept a proton
1. CO₃⁻² + H₂O ⇄ HCO₃⁻ + OH⁻
Carbonate takes a proton from the water
2. HCO₃⁻ + H₂O ⇄ H₂CO₃ + OH⁻
Bicarbonate takesa proton from the water to produce carbonic acid.
3. H₂CO₃ → H₂O + CO₂
Carbonate acid decomposes into CO₂ and H₂O
In the first reaction, when the carbonate takes a proton from the water, water releases OH⁻, so the solution is basic.
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
