Explanation:
A conservationist is someone who advocates and champions the cause to protect the environment and use earth's resource in a sustainable way.
One of the interesting perks of being a conservationist is the ability to preserve pristine nature.

- The joy of having to enact laws and policies that would preserve very vital aspect of the ecosystem would such a great delight.
- Also, having to champion the cause of indigenous people in whose voices are not often disseminated is a good catch
Answer:
1) Add more sulfate ions.
2) 1 M K₂SO₄.
Explanation:
<em>1) Which of the following actions would shift this reaction toward solid barium sulfate?</em>
<em></em>
- Le Châtelier's principle states that if a stress is applied to a system at equilibrium, the system will shift to relieve that stress and attain the equilibrium again.
Add more sulfate ions will increase the concentration of the products side, so the reaction will be shifted towards the reactants side to relieve the stress and attain the equilibrium again.
<em>So, the right choice is: Add more sulfate ions.</em>
<em></em>
<em>2) In which of the following would barium sulfate be least soluble? </em>
The answer is 1 M K₂SO₄, it has a common ion effect of SO₄⁻ ions that increase the concentration of the products side, so the reaction will be shifted towards the reactants side to relieve the stress and attain the equilibrium again.
<em>So, the solubility will decrease.</em>
