How can you determine experimentally whether or not a substance is present in ionic or molecular form when in aqueous solution?
If the solution will conduct electricity it is ionic. Solutions made from molecules do not conduct electricity.
Do the suffix in front of the water molecule in a hydrate name represent the number of water molecules attach to the ionic compound?
Yes. The suffix does indeed give the proportions of water molecules and ions in the compound. The water molecules are somtimes coordinated around ions sometimes they are present in the lattice uncordinated to ions.
How many sugar molecules are present in 300 mL of a 2.0 molar solution?
By the definition of molarity, a 2.0 molar solution contains twice Avodagro's Number of molecules per liter. Therefore, the stated solution contains 0.300X2X6.022Xten to the 23rd power = 3.6X ten to the twenty-third power sugar molecules. (Only two significant digits are justified, because the molarity is specified with only two significant digits.)
Does pH measure the total number of acid molecules in a solution?
No.pH measures the total number of hydronium ions or H+ ions present in an acid and the strength of that acid
What intermolecular forces are present in cl2?
London forces are present in chlorine molecules.
Does sugar crystals change shape when they are in water?
I a water sugar solution creystals doesn't exist, molecules are present.

How many molecules of glycerole would be present in a 1 L 1 mol gylcerol solution?
This is the Avogadro number - 6,022 141 29(27) .10 ex. 23 molecules.
What do percent proportion?
Ratios or fractions can be used to present proportions.
What are identification tests of phenol?
You add a specific ionic compound in a solution to determine if phenol or any of its derivatives are present. Ferric chloride (FeCl3) for example, can be used for such tests. Basically, when you mix the solution with the compound, the ions will interact with the phenol molecules or groups, and as a result, the solution will briefly change color. If there is no colour change in the solution, this suggest there is no phenol or phenol-based molecules in your solution.

Why petrol is volatile than water?
Water molecules have polar characteristics. They have strong intermolecular bonds, namely, hydrogen bonds. But the only intermolecular force present between petrol molecules is London forces which is relatively very weak than hydrogen bonding.
Does pH measure the total number of acid molecules in a solution?
No.pH measures the total number of hydronium ions or H+ ions present in an acid and the strength of that acid
What geometries tend to be present in polar molecules?
Trigonal planar and tetrahedrral geometries tend to be present in polar molecules.
