Calculate the specific heat capacity of a new alloy if a 15.4 g sample absorbs 297 Joules when it is heated from 5.0 °C to 20.7 °C. The key assumes you are giving your answer in Joules/g°C and rounding to 2 or 3 sig figs

Suppose you got a low yield of benzoin from your benzoin condensation reaction and thus only have 0.300 g of benzoin to use as the starting material for this reaction. how much concentrated nitric acid should you add? (concentrated nitric acid is 15.8 m). write your answer in the form x.xx ml

3.) for each of the following compounds, draw the major organic product of reaction with hcl or naoh and circle whether the starting materials and products will be more soluble in organic solvent or water benzoic acid + hcl: benzoic acid + naoh: oh benzoic acid water/organic water organic fluorenone hс: fluorenone + naoh: fluorenone water/organic water/organic веnzocaine + hci: benzocaine + n»oh: h2n benzocaine water/organic water organic o=

Avariable that is not being directly tested during an experiment should be
