What is the percent composition of sulfur in SO2?
A. 32.1 g (32.1 g + 16.0 g + 16.0
x 100%
B. (32.1 g)(6.02 x 1023) 100 g
C. (32.1 g + 16.0 g+ 16.0 g) х 100%
32.1 g
D. 32.1 g (16.0 g + 16.0 g)
x 100%

alchemy hadn't scientific methods of study, appeal to mysticism and fantasy, the knowledge of chemistry and physics were modest at that time.

alchemy was - but as new rules were discovered it either changed into chemistry or it became "unscientific".

35. a insulated cylinder of solid gold (k 310 kw/m-k) of radius v2 m and height 5 m is heated at one end until the temperature at each point in the cylinder is given by w(r, y, z) (30 z2)(2-(r2+ y2). determine the rate of heat flow across each horizontal disk given by z 1, z 2, and z 3, identifying which has the greatest rate of heat flow across it.
