During the cooling of the naphthalene why the boiling tube must be placed in a conical flask?
ensure even cooling of the napthalene
How might a scientist distinguish the compounds stronium chloride and patassium chloride?
They are both fine white powder type crystals with high Mp's so I would go with density or molar mass. The molar mass of strontium chloride is 158.53 (anhydrous, and up to 266.62g/mol at it's most hydrated) and of potassium chloride is 74.55g/mol. You could so a density test but for that you must make sure to use the anhydrous form. I believe the density of strontium chloride is 3.05g/cm3 (when it is anhydrous) and potassium chloride is 1.98g/cm3. The problem with this is if stontium chloride's density can be recorded as low as 1.93 depending on how hydrated it is so in order to this accuratedly you must use the anhydrous form.
What must you do to a substance to get it to change its state of matter?
That is done by either heating or cooling.
What is the difference between anhydrous ammonia and aqua ammonia?
Anhydrous ammonia is standard, commercial grade ammonia. The term "anhydrous ammonia" emphasizes the absence of water in the material. Because ammonia boils at -33.34 °C, the liquid must be stored under high pressure or at low temperature. Aqua ammonia is another name for ammonium hydroxide, a solution of ammonia in water. This is the household ammonia offered in stores and used in some cleaning products.
How to convert benzynoic acid to phenol?
You must initially convert it into benzene then heat it with Zn dust. And add CH3-Cl+anhydrous AlCl3 followed by hot concentrated KMnO4.
How do you estimate anhydrous magnesium sulfate is enough to use?
You must state the purpose of using MgSO4.
How do you repair when engine oil has gotten into the cooling system?
You have a blown head gasket, cracked head, or both. The engine must be dissembled to make the repair. Stop driving this car immediately or you will destroy the engine.

ensure even cooling of the napthalene
What type of road sign instructs a driver of actions that must be obeyed immediately?
These signs instruct a driver of actions that must be obeyed immediately
If time is matter why?
no because time must be measured.
What artistic standard must a building be measured?
Fk
Why must an object to be measured grams be at the center of the balance?
Not true, it must be on a balance pan.

How do you get an air lock out of your cooling system?
COOLING SYSTEM OF WHAT ??????????????????????? Most auto parts stores sell cooling flushing kits. Get one follow the directions and it should take the air out of the system. You must remember that your heater is part of the cooling system as well as the cooling for your transmission.
what is the dependent variable in heating and cooling curve water?
it must be an atom
How do you bypass engine cooling fan resistor on 2002 ford focus?
This is only a temporary solution to the problem, if you must drive the vehicle and cannot get the part immediately (Please replace this part ASAP) *****BY TURNING THE A/C SWITCH ''ON", this will activate and turn "ON" the radiator Cooling Fans***** if you cannot locate the part, TEXT (ONLY) me at 7177560938 (Again, Please do not call, TEXT ONLY
How would you find the density of a lump of sodium that is about 10 grams?
The volume must be determined; try the method of liquid displacement using an anhydrous mineral oil.
