A non-chlorine chemical such as iodine may be used as a
sanitizing solution. To use iodine as a sanitizing solution, it should be
around 12.5-25 ppm in water that is at least 75° F. Utensils and equipment must
be immersed for only 30 seconds because it may lose its effectivity if the pH
level gets too high due to high temperature. Discoloration may also result if
the utensils and equipment are in prolonged contact with the solution.
Answer:
The mass of the precipitate that AgCl is 3.5803 g.
Explanation:
a) To calculate the molarity of solution, we use the equation:
We are given:
Mass of solute (NaCl) = 1.46 g
Molar mass of sulfuric acid = 58.5 g/mol
Volume of solution = 
Putting values in above equation, we get:
0.09982 M is the concentration of the sodium chloride solution.
b) 
Moles of NaCl = 
according to reaction 1 mol of NaCl gives 1 mol of AgCl.
Then 0.02495 moles of NaCl will give:
of AgCl
Mass of 0.02495 moles of AgCl:
The mass of the precipitate that AgCl is 3.5803 g.
They are substitution reactions
hope that helps
Answer:
In the northern hemisphere I believe, Scorpius is most visible by looking to the south during July and August around 10:00 PM. The constellation remains visible until mid-September.
