(a) an optically inactive mixture a (c6h10o4) can be resolved into enantiomers and has the following nmr spectra: 13c nmr: δ 13.5, δ 41.2, δ 177.9 1h nmr: δ 1.13 (6h, d, j = 7 hz); δ 2.65 (2h, quartet, j = 7 hz); δ 9.9 (2h, broad s, disappears after d2o shake) draw either enantiomer; use wedge/dash bonds, including for any h on a chirality center.

the temperature of the gas, in k, not celsius.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
