An animal cell Presume its normal volume when it is placed in a solution with a total electrolyte molarity of 0.3 M. Suppose if the cell is placed in a solution with a total molarity of 0.6 M, then explain what happens?
More water enters than leaves the cell, causing it to burst
More water leaves than enters the cell, causing it to shrink
The volume of the cell stays constant
No movement of water across the membranes takes place
The electrolyte molarity outside the cell cannot be higher than inside the cell.
a solution is made by dissolving 15.5 grams of glucose c6h12o6 in 245 grams of water. what is the freezing-point
explain the following observations: a)an open can of soda loses its "fizz" more quickly at room temperature than in the refrigerator. b) chlorine gas in tap water escapes as the sample warms to room temperature. c)less sugar dissolves in iced coff..
The goes like... "A balloon containing 35.5grams of Cl2 and 38.0 grams of F2" (then somewhere along in teh question it says "the volume is increased to 10L"
A sample of S8 (g) is placed in a container at 1325 K at an initial pressure of 1.00 atm, where it decomposes to S2 (g) by the reaction, S8 (g) 4S2 (g), At equilibrium, the partial pressure of S8 (g) is 0.25 atm. The Kp at 1325K is
We want to know the pressure at this condition, but there is no means of measuring it since the tube is sealed. However, if the tube is cooled to -20 degrees celcius, small droplets of liquid are observed on the glass walls. What is the initial pr..

explain why there are significant color changes that occur insubstitution reactions. talk about the origins of color
Suppose 50 mL of 0.250 M CoCl2 solution is added to 25.0 mL of 0.350 M NiCl2 solution. Calculate the concentration, in moles per liter, of each of the ions present after mixing.
Is it true that Ksp is an equilibrium constant that can be used to express quantitatively the extent to which a compound dissolves
Write a mathematical equations that show how you will calculate the deteced activity from the count rate due to background radiation and the sample of KCl. also, write an equation that shows how you will determine the "true" activity of your sampl..
You are given an unknown (solid or solution) and told that it can be one of the other of the compounds in the pairs listed below. Describe a simple chemical test (Not a flame test) using only reagents from our chemistry kits that would enable you ..
Borazine has the formula (BHNH)3. The combination of a boron atom and a nitrogen atom is isoelectronic with two carbon atoms. How would you draw the stucture of borazine?
