Answer:</h3>
Ba(NO₃)₂(aq) + CuSO₄(aq) ⟶ BaSO₄(s) + CU(NO₃)₂(aq)
2K₃PO₄(aq) + 3MgCl₂(aq) ⟶ 6KCl(aq) + Mg₃(PO₄)₂(s)
<h3>
Explanation:</h3>
- Precipitation reactions are types of reactions that involve a reaction between soluble salts to form an insoluble salt or a precipitate and a soluble salt.
- The equations given in the question are examples of precipitation reactions that lead to the formation of precipitates BaSO₄ and Mg₃(PO₄)₂
- The balanced equations are;
Ba(NO₃)₂(aq) + CuSO₄(aq) ⟶ BaSO₄(s) + CU(NO₃)₂(aq)
2K₃PO₄(aq) + 3MgCl₂(aq) ⟶ 6KCl(aq) + Mg₃(PO₄)₂(s)
- Based on solubility rules, all sulfates are soluble except CaSO₄, BaSO₄, PbSO₄ and silver sulfate. Therefore, BaSO₄ is a precipitate and will have a solid-state.
- All phosphates are insoluble except those of ammonium, potassium, and sodium. Therefore, Mg₃(PO₄)₂ is a precipitate and will have a soluble state.
Answer:
Explanation:
In organic chemistry, the reaction between 2-butanol with TsCl and Et3N is known as the tosylation of the alcohol hydroxyl group. Alcohol is being changed to tosylate by the use of tosyl chloride under the influence of a base. Tosylation of alcohol is an example of a nucleophilic substitution reaction. From the image attached below, we will see how the reaction between 2-butanol proceed into the product by using tosyl chloride and a base(Et3N).
Answer:
Intraspecific competition examples,
Interspecific competition examples,
and what causes it to happen. <em>Skip to the bottom for shortest answer.</em>
- Intraspecific competition is for instance, when two cows of the same species compete for grass, the food source.
- Interspecific competition is for example, when a bear and another species compete for fish.
But why does this happen? ↓
This competition happens because of limiting factors in the ecosystem, and general competition. Animals compete for their food because they need this food to survive. If they do not compete for the food, the other animal will get the food and the opposing animal will be left hungry. These are the main reasons why animals will compete for their resources.
In conclusion,
In a short sum, competition happens because animals need food, and when they can't get food, they compete.
