If the gas in the piston above has a volume of 20.0 L at a temperature of 25 C what is the volume of that gas when it is heated
dexar [7]

Answer:

15.98 L

Explanation:

First, you need to find T1, T2, V1 and V2.

T1 = 25 C = 298.15 K (25C + 273.15K)

T2 = 100 C = 373.15 K (100C + 273.15K)

V1 = 20. L

V2 = ? (we are trying to find)

Next, rearrange to fit the formula

V2 = V1 x T1 / T2

Next, fill in with our numbers

V2 = 20. L x 298.15 K / 373.15 K

Do the math and you should get...

15.98 L

- If you need more help or futher explanation please let me know. I would be glad to help!

Which of the following features is common to both acids and bases? A. ability to burn skin B. similar taste C. pH measurements g
Lynna [10]
<h3>Answer:</h3>

            Correct Option-A (Ability to burn skin)

<h3>Explanation:</h3>

                    When skin tissues are exposed to Acids or Bases a chemical burn occurs as both of these substances are corrosive in nature. These burns occur without providing any heat, results from a very fast reaction, are extremely painful and causes damage to structures present under skin.

                    Option-B is incorrect because Acids taste sour, while, Bases taste bitter.

                    Option-C is incorrect because pH of Acids is less than 7 while, pH of Bases is greater than 7.

How does the amount of salt dissolve in water affect the density of water
ad-work [718]

Answer:

Adding salt to the water increases the density of the solution because the salt increases the mass without changing the volume very much. When you add table salt (sodium chloride, NaCl) to water, the salt dissolves into ions, Na+ and Cl-. The volume increases by a small factor, but the mass increases by a bigger factor.
