Use the standard reaction enthalpies given below to determine ΔH°rxn for the following reaction: P4(g) + 10 Cl2(g) → 4 PCl5(s) ΔH°rxn = ?

Given:

PCl5(s) → PCl3(g) + Cl2(g) ΔH°rxn = +157 kJ

P4(g) + 6 Cl2(g) → 4 PCl3(g) ΔH°rxn = -1207 kJ

1. calculate the approximate enthalpy of the reaction in joules. estimate that 1.0 ml of vinegar has the same thermal mass as 1.0 ml of water. iqnore the thermal mass of th sodium bicarbonate. note: it takes about 4.2 joules () to change 1.0 gram (1.0ml) of water 1.0 c

If a plot weight (in g) vs. volume (in ml) for a metal gave the equation y= 13.41x and r^2=0.9981 what is the density of the metal?

Type the letter that represents the correct location for each particle type below.
