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.

What is the number of moles in 15.0 g ash3?

Which statement describes covalent bases? they have hydroxide ions. they produce hydrogen ions. they are often amines. they are named the same as ionic compounds.

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
