Study the following two reactions. (select all that apply.) c(graphite) + o2(g) co2(g) + 94.05 kcal c(diamond) + o2(g) co2(g) + 94.50 kcal
what could you infer from the information given above?
- the enthalpy of co2 is greater than the reactants.
- e2 - e1 is negative.
- graphite and diamond have equal enthalpy.
- both reactions are exothermic.

the region consisting of the points $(x,y)$ that satisfy \[-6 \le 3x - 5y \le 6\]and \[-3 \le x + 2y \le 3.\]Plot the region $\mathcal{R},$ and identify the vertices of polygon $\mathcal{R}.$ (b) Find the maximum value of $x + y$ among all points $(x,y)$ in $\mathcal{jihi
