P3C.6 Use values of enthalpies of formation, standard entropies, and standardheat capacities available from tables in the Resource section to calculate thestandard enthalpy and entropy of reaction at 298K and 500K for 12 N2(g)+ 32 H2(g) → NH3(g). Assume that the heat capacities are constant over thetemperature range involved.

answer carbon and three oxygen atoms;

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.

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".
