Amps = volts / resistance. Watts = amps * volts. Joules = watts * seconds. Things that effect resistance, and their effects on product versus waste heat and rate of production: Adjusting each parameter individually: Voltage: Per unit of energy supplied, in general, a lower voltage produces more product and less waste heat from electrolysis.

There is a lot of work associated to create such a database, or software.

On the other hand, most of the reactions of phenol depend upon its. Weaker O−H O − H bond ( i.e., acidic nature): Reimer-Tiemann reaction, etc. Thus phenols and alcohols don't have too many reactions in common.

This is a 10th-grade question. The melting point of a substance decreases with increase in presence of impurities in it. The melting point of ice decreases from 0 °C to -22 °C on mixing salt in it in proper proportion. That is why salt is added to make freezing mixtures to keep ice creams frozen.Nov 28, 2019 · Now, coming to indium oxide, the formula of this compound as stated here is InX2OX3 I n X 2 O X 3, which bears a resemblance to the formula of AlX2OX3 A l X 2 O X 3 and GaX2OX3 G a X 2 O X 3 which we stated above. So, I would expect this oxide to atleast have some amphoteric properties. The key point in carbohydrate numbering is to look for the carbon which is an aldehyde or a ketone (the carbonyl carbon). This will be the end of the monosaccharide which is numbered lowest. For aldoses, this carbon would be carbon 1. For ketoses, it's the lowest number that can be reached in the linear, ring-open form (e.g. for fructose, it's 2).Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry.
