Problem- Consider the reaction: CaCO3(s)---->CO2(g) + CaO(s). Estimate G for this reaction at each temperature. (Assume that ?H? and ?S? do not change too much within the given temperature range.) B. 1060 K C. 1480K.
Please demonstrate all work. Thank you in advance
Problem- The NO molecule is a free radical, and the unpaired electron could be spin up (alpha) or spin down (Beta). This means that the electronic ground state has two degenerate states.
Determine the range of fat you might expect to obtain if you extracted fat from ten grams of nutmeg (Dried, ground nutmeg typically contains between 20-25% fat by weight.) Assume that your extraction is 95% effective.
The molar mass of cellulose is approximately 6.0 x 105 g/mol and the molar mass of a soluble starch is on the order of 4.0 x 103 g/mol. The monomer unit in both of these molecules has the emperical formula C6H10O5
