Answer:
Is the fixed number of water molecules present in one formula unit of a substance
Explanation:
When copper sulphate is heated in a china dish, the blue colomed crystal changes to a white powder due to the removal of molecules of water of crystallization
2 x 3 = 6 + 3 x 3 = 9. 6 +9= 15 + 5 = 20. 10 + 15 = 25.
So, The Al2 O 3 is 20.
And the Fe is 15?
So the total of whatever it is is 25.
Sorry if it's wrong, I am a 13year old 7th grader, not in high school so it's probably wrong.
<h3><u>Answer;</u></h3>
D. It decreases and the pH increases.
<h3><u>Explanation;</u></h3>
- pH is a measure of the hydorgen ion concentration of a solution. Solutions with a high concentration of hydrogen ions have a low pH and solutions with a low concentrations of H+ ions have a high pH.
- <em><u>[H+] and [OH-] are inversely related. Therefore; As the concentration of H+ increases the pH decreases. Since the concentrations of H+ and OH- are inversely proportional, as one goes up, the other goes down. </u></em>
- <em><u>Therefore, an increase in OH- concentration will correspond to an increase in pH and a decrease in the concentration of H+.</u></em>
