Question

In photosynthesis, glucose, $\mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}$, and $\mathrm{O}_{2}$ are produced from $\mathrm{CO}_{2}$ and $\mathrm{H}_{2} \mathrm{O}$. Glucose from starches is the major fuel for the body. $6 \mathrm{CO}_{2}(g)+6 \mathrm{H}_{2} \mathrm{O}(l)+680 \mathrm{kcal} \longrightarrow \mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}(a q)+6 \mathrm{O}_{2}(g)$ Glucose a. Is the reaction endothermic or exothermic? b. How many grams of glucose are produced from $18.0 \mathrm{~g}$ of $\mathrm{CO}_{2}$ ? c. How much heat, in kilojoules, is needed to produce $25.0 \mathrm{~g}$ of $\mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6} ?$
