What does the pH of a solution have to be in order to be a base?
VMariaS [17]

Explanation:

pH is used to measure the concentration of H+ ions ([H+]) and therefore, whether a substance is acidic or basic (alkaline). Solutions with a pH of less than seven are acidic, while those with a pH greater than seven are basic (alkaline).

the temperature of a balloon rises from 275 degrees k to 395 degrees k, what would the ending volume be if it started at 5 L
Airida [17]
<h3>Answer:</h3>

7.182K

<h3>Explanation:</h3>

From the question we are given;

  • Initial temperature, T1 = 275 K
  • Final temperature, T2 = 395 K
  • Initial volume, V1 = 5 L

We are required to calculate the final volume, V2

  • Charles's law is the law that relates the volume of a gas and its temperature.
  • It states that the volume of a fixed mass of a gas and its absolute temperature are directly proportional at a constant pressure.
  • Therefore;

\frac{V1}{T1}=\frac{V2}{T2}

To calculate, V2 we rearrange the formula;

V2=\frac{V1T2}{T1}

V2=\frac{(5L)(395K)}{275}

V2=7.182K

Therefore, the ending volume will be 7.182K
