Now assume you measure out exactly 2.0 ml of aluminum chloride into a third test tube How many moles of aluminum chloride are in the tube?
That depends upon the concentration of the solution. If it is a 1 molar solution, then 2 ml contain .002 moles.
What is the heat of solution for sodium chloride in joules assume that the specific heat capacity of the system is the same as that for water?
The standard enthalpy for the change in solution is: +3,87 kJ/mol at 25 0C
What is the molarity of chloride ion in 100 ml of a 500 M barium chloride solution?
I assume you mean 0.5 molar, but I'll go with what I'm given. If you have 500 molar of barium chloride, you will have 1000 molar of chloride ions as there are 2 chlorides for every 1 molecule of barium chloride. Having the 100ml there is irrelevant as you are talking about concentration and didn't ask for moles.
What is the value of log e?

Is there benefit to adding saline to a ventolin nebulizer treatment?
Ventolin contain an isotonic solution of salt; I assume that pharmacists have thought better. Sodium chloride has also an antibacterial effect.
The blue color in the copper sulfate solution is due to the presence of what ion?
Since copper (I) chloride has only limited solubility in water I will assume you mean copper (II) chloride, CuCl2. Then the ions will be Cu2+ and Cl-.
Why do you use ammonium chloride rather than only water in the of the grignard reaction?
It acidifies the solution, so we can protonate and generate the alcohol in the final step. I assume you're making an alcohol from a ketone or ester?
Assume that a solution forms the product mercury liquid acetate The product formed is?
Assume that a solution forms the product mercury (I) acetate. The product formed is _______.
How many days are there in a week on the planet Uranus?
As far as I know, a week is defined as seven days. I do not know of any direct astronomical significance that can be measured exactly, so on Uranus, I would assume weeks would be measured in "Uranus days," so there would be 7 days in a week as usual.
Is magnesium chloride acid base or neutral in water?
Theoretically, the magnesium ion undergoes a tiny amount of hydrolysis. But this amount is so small that it realistically has no effect on the solution. So, in reality, it is neutral.
What is the chemical formula for sodium clorde?
I assume that you mean sodium chloride, in which case the chemical formula is NaCl.
Can movement only be measured with reference that is assumed to be fixed in pace?
No, Einstein proved that all inertial frames are equally valid references. You don't have to assume it's "fixed in place" or even know exactly how it's moving relative to any other frame as long as you know how the measured object is moving relative to the chosen reference frame.
