2.07 M is the molarity of the final solution if 45.0 ml of 6.00M HCl is added to 130 ml of
O.
Explanation:
Data given:
volume of HCl, V1 = 45 ml
molarity of the HCl solution, M1 = 6 M
final volume of the HCl solution after water is added, V2 = 130 ml
final molarity M2 =?
After the dilution, the molarity of the new solution can be found by using the formula:
M1V1 = M2V2
here M1 and V1 are the molarity and volume for concentrated solution, M2 and V2 represents the diluted solution's molarity and volume.
Applying the formula after rearranging the equation, we get
M2 = ![\frac{M1V1}{V2}](https://tex.z-dn.net/?f=%5Cfrac%7BM1V1%7D%7BV2%7D)
M2 = ![\frac{6X45}{130}](https://tex.z-dn.net/?f=%5Cfrac%7B6X45%7D%7B130%7D)
M2 = 2.07 M
The final molarity of the HCl solution is 2.07 M
bacterial growth
Explanation:
Excessive bacterial growth is one of the example of a natural process that causes water pollution.
Pollution is the undesired concentration or harmful introduction of a particular body into the environment and causes harm overall.
- Pollution can result from both natural and anthropogenic sources.
- Anthropogenic causes of pollution are the most common due to activities of human beings.
- Natural causes of pollution results from the activities of nature in itself.
- From the given options, the bacterial growth is an natural process of pollution.

Hello there! We don't consider Ice usable, so the answer would be option D) ice.
Hope this helps!
Answer:
b
Explanation:
This means that it takes more energy or heat to increase water's temperature than it does for most other substances. The specific heat of water is greater than that of dry soil, therefore water both absorbs and releases heat more slowly than land.
Hello there,
You dont have any option's, But I will be more than happy to (try) to help you.
Sour milk could make a stomach upset.
Milk has a limited time until it can not be drink-able.
I hope that can help,You didn't have any option's to lay out, I hope that help's.
