Answer:
<u></u>
Explanation:
Normally, in the neutralization reactions, that is how the reactions between and acid and a base are called, you assume additive volumes.
Additive volumes means that the <em>volume</em> of the final <em>solution</em> is equal to the sum of the separate volumes of the two solutions that are mixed.
It is not totally accurate, but it is a good approximation and for lack of additional data it is what is used.
Then, assuming additive volumes:
- Total volume of the solution = 100 mL + 250 mL = 350 mL.
Answer:
c. temperature and water vapor content.
Explanation:
The density of any substance is dependent of temperature, and in gases, the variations is greater than in any other substance, therefore, temperature is very important to calculate air density. Also, the concentration of water vapor in the air can vary depending where is located, and that concentration will affect the density because it affects the average mass of air.
1.) A compound is a thing that is composed of two or more (separate) elements.
2.) A compound cannot be separated easily, while its properties differ from where it originates from. It also is formed from chemical reactions.
3.) A pure substance, also known as chemical substance, is a material with constant composition and consistant properties.
4.) If a substance is not a pure substance, then it is an impure substance.
Hope this helped. :)
<u>Answer</u>:
"weathering breaks rocks into minerals and plants die and decay" must occur to form soil
<u>Explanation</u>:
For the formation of the soil two process are mandatory and they are erosion as well as weathering. The weathering takes place near the surface of the soil, which can occur due to various physical and chemical processes. Being an important part of soil development. It may occur rapidly or can be a slow process for decades. Water and air helps in weathering. The transport is generally by wind or with the help of flow of water, ice, etc
