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.

Calculate the molarity of the solution. 6.02 x 1022 molecules of hci (molecular weight = 36.5 g/mole) in 2.0 liters of water m

Aglow stick contains a glass vial with chemicals. when the glow stick is bent, the vial breaks and the chemicals react to produce a glow. a science student observes that a glow stick kept in the freezer glows for a longer duration than a glow stick kept at room temperature. what conclusion can be drawn based on the observation? be sure to note the outcome and test variables in the conclusion.

Which fact represents evidence for the big bang theory?
