Recall the equation M, VA = M2V2. Based on the presence of this amount of copper sulfate, complete the table to predict the concentration of the solution as water is added to the tank or removed from it. Don't actually change the amount of
water in the tank yet.
Type the correct answer in each box. Use numerals instead of words. Express each answer to two significant figures e.
Volume (L) Concentration (mol/L)
1.0
0.80
0.60
0.50
0.40
0.20

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a

the answer is true. hope it .

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
