Answer:
lake water, swamp water, like, any dirty and unpurified forms of water is hard water
Explanation:
<h3>
Answer:</h3>
#1. Type of reaction: Single displacement
#2. Balanced equation: Zn + 2HCI → ZnCI₂ + H₂
<h3>
Explanation:</h3>
<u>We are given;</u>
- The equation; Zn+HCI → ZnCI₂ + H₂
Assuming we are required to identify the type of reaction and balance it;
- The reaction is a <u>single displacement reaction.</u>
- Zinc metal displaces hydrogen atom from hydrochloric acid to form a salt, zinc chloride and hydrogen gas.
- To balance the equation, we put coefficients on the reactants and products for the number of atoms of each element to be equal on both sides of the equation.
- In this case, the appropriate coefficients are 1, 2, 1 and 1
- Therefore, the balanced equation will be;
Zn + 2HCI → ZnCI₂ + H₂
Given what we know, we can confirm that option A is correct in that Stronger IMFs lead to stronger adhesion, producing rounder drops with a smaller diameter.
<h3>What are IMFs?</h3>
IMF is the acronym used to describe intermolecular forces. These forces include all of the forces that bind molecules together, of which water has plenty. This bonding force creates a high adhesion and thus gives water its surface tension which makes it stay together in the shape of a drop.
Therefore, we can confirm that stronger IMFs lead to stronger adhesion, producing rounder drops with a smaller diameter, and therefore that option A is correct.

Answer: The correct answer is "refrigeration".
Explanation:
Refrigeration is the process of rejecting heat from low temperature reservoir and transfers it to high temperature reservoir. Here, the heat is taken from the colder body and reject it to hotter body. The sink is at the lower temperature. The source is at the higher temperature.
In heat engine, the heat is transferred from high temperature reservoir to the low temperature reservoir. It is just opposite of the refrigeration.
Therefore, going against the natural flow of heat and moving thermal energy from a low temperature to a high temperature is refrigeration.
