Suppose that 28g of each of the following substances is initially at 28.0 degrees celcius. What is the final temperature of each substance upon absorbing 2.45 kJ of heat?1.gold2.silver3.aluminum4.water
Hydrogen bonds a) play an important role in the solvent properties of water b) are not involved in protein structure c) play a role in the properties of DNA, but not of RNA d) give water a lower boiling point than expected 44
high boiling point are obtained now you need to identify the limiting reagent and compute the percent yield of nitrobenzene
