Use the information in the table below to answer the following question:
Lake Volume Buffer (CaCO3) Concentration
Squirrel Lake,80,000 Liters,2 mg/L
Moose Lake,100,000 Liters,1.6 mg/L
Question 1 :
The total amount of buffer in Squirrel lake is___
mg. (Type only numbers in the box)
Question 2:
The total amount of buffer in Moose Lake is
mg. (Type only numbers in the box)

Both are 160,000 mg.

Explanation:

So the total amounts of buffer are going to be expressed in mg (in your case). This means you can take the concentrations (in mg/L) and multiply by the volumes (in L) to get your amounts mg.

For Squirrel Lake:

2 mg/L * 80,000 L = 160,000 mg

For Moose Lake:

1.6 mg/L * 100,000 L = 160,000 mg

the answer

explanation:

the capillary tube was too close to the bottom of the beaker.

the ruler may have moved.

water got into the capillary tube.

the temperature was not allowed to equilibrate in the 2-4 minutes.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
