Draw the Fischer projections of the four aldotetroses. Draw the D sugar on the left and its L isomer directly to the right of it. Switch between an aldose and a ketose by clicking on \"switch carbonyl group.\" Add or delete carbon atoms using the add (\" \") or delete (\"x\") buttons. Clicking on a blue box once adds a hydrogen atom (H). Clicking on a blue box again toggles between H and OH.

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
