Answer:
Explanation:
Bisulphate ion is a weak acid as it can form hydronium ion in water .
HSO₄⁻ + H₂O ⇄ SO₄⁻² + H₃O⁺
The equilibrium constant of this reaction is very small , hence bisulphate ion is very weak acid.
Answer:
a. overuse of resources is the correct answer.
Explanation:
Renewable resources are available and they are abundant but overuse of these renewable resources will have a negative effect on the surroundings and humans.
Overuse of renewable resources will leads to the depletion of these renewable sources in the future and will also make the ecosystem unbalance.
Renewable resources are solar energy, geothermal energy, biomass energy, wind energy, hydro energy.
Thus renewable resources are threatened due to overuse and it must be carefully used.
D) Radioactive contamination
A scientific law is a statement that is universally accepted and answers the "how?" question.

Solids have a definite shape and volume. They are always the same shape no matter what they are contained in; their volume is also the same because they don't change unless you add or take away from it.
____________________________________________________________
Liquids have an indefinite shape but definite volume. They expand to fill out the space they are contained in, but their volume doesn't change unless you take out or add more of the liquid.
Gases have an indefinite shape and volume. Gases expand to fill out the space they are in and also don't have a clear shape because they are not always in one form.
