When cloud particles become too heavy to remain suspended in the air, they fall to the earth as precipitation. Precipitation occurs in a variety of forms; hail, rain, freezing rain, sleet or snow.
When the temperature is too hot for snow it'll rain and if the tempature is too cold it will freeze the rain and that's how you get snow or hail.
Hope this helped :)
Have a great day
<h3><u>Answer</u>;</h3>
pH =7.58
<h3><u>Explanation;</u></h3>
The KOH will react with the HClO to produce KClO. You will have a solution containing unreacted HClO and KOH. This is a buffer solution.
Equation:
HClO + KOH → KClO + H2O
HClO reacts with KOH in 1:1 molar ratio
Mol HClO in 50mL of 0.150M solution = 50/1000*0.150 = 0.0075 mol HClO
Mol KOH in 30mL of 0.150M solution = 30/1000*0.150 = 0.0045 mol KOH
These react to produce 0.0045 mol KClO and there is 0.0030 mol HClO unreacted
Volume of solution = 50mL + 30mL = 80mL = 0.080L
Molarity of HClO in solution = 0.0030/0.080 = 0.0375M
Molarity of KClO in solution = 0.0045/0.080 = 0.0562M
Using the Henderson-Hasselbalch equation we can calculate the pH;
pKa HClO = -log ( 4.0*10^-8) = 7.40
pH = pKa + log ([KClO]/[HClO])
pH = 7.40 + log( 0.0562/0.0375)
pH = 7.40 + log 1.50
pH = 7.40+ 0.18
pH = 7.58
Answer:we can calculate pH
