You have 100 mL of a 2.0 M aqueous sugаr solution. If you dilute this solution to a volume of 300 mL, which of the following is true?
Moles of solute and concentration will stay the same
Moles of solute will decrease, concentration will stay the same
Moles of solute stays the same, concentration will decrease

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.

35. a insulated cylinder of solid gold (k 310 kw/m-k) of radius v2 m and height 5 m is heated at one end until the temperature at each point in the cylinder is given by w(r, y, z) (30 z2)(2-(r2+ y2). determine the rate of heat flow across each horizontal disk given by z 1, z 2, and z 3, identifying which has the greatest rate of heat flow across it.
