Answer:
The pH of the solution is 1.66
Explanation:
Step 1: Data given
Number of moles HCl = 0.022 moles
Molar mass of HCl = 36.46 g/mol
Step 2: Calculate molarity of HCl
Molarity HCl = moles HCl / volume
Molarity HCl = 0.022 moles / 1 L = 0.022 M
[HCl] = [H+] = 0.022 M
Step 3: Calculate pH
pH = -log [H+]
pH = -log(0.022)
pH = 1.66
The pH of the solution is 1.66
It has four valence electrons

I hope it's help u :)
Answer:
if an object is getting colder it is loosing thermal energy
<span>The first blank is 2 hours and the second blank is 4 hours. Temperature control is extremely important in food handling, because the incorrect usage can cause harmful bacteria to grow in the food. However, this bacteria doesn't live grow very well when the food temp is hotter than 135 degrees or cooler than 41 degrees. In regard to the second question, you will need to put on a new pair of gloves any time they are contaminated or damaged. This way, the food will never come into contact with your skin or with the contamination.</span>
