I did a chem lab project to determine the solubility and conductivity of six compounds, and I know I've messed some results up but I can't figure which ones. If you could go through these and tell me which ones are wrong, I would really appreciate it.

paraffin - soluble r.t. water: no soluble hot water: no soluble in r.t. mineral spirits - no soluble in hot mineral spirits - yes conducts - no

dichlorobenzene - r.t. water, hot water, r.t. mineral spirits - no hot mineral spirits - yes conducts - yes

hydroquinine - r.t. water - no hot water, r.t. spirits - yes hot spirits - no conducts - no

sugar - r.t. water - no hot water - yes r.t. spirits, hot spirits - no conducts - yes

sodium nitrate - r.t. water, hot water - yes r.t. spirits, hot spirits - no conducts - yes

potassium chloride - r.t. water - no hot water - yes r.t. spirits, hot spirits - no conducts - yes

Thank you!

I bought a router in USA its power specs are as follows..
Input: 100-120v~0.5A, 50~60Hz
Output: +5.0V---2.5A
The power output in India is 240V so i will obviously need a step down transformer. These transformers have specs of 100W to 15000W, now the question is how many Watts transformer will suite my router's inputs specs.
Please help me select a transformer...
here is a link of these transformers...
