Blood sugar, glucose, has a molar mass of 180 g / mol.  What is the molecular formula of glucose if the empirical formula is CH2O?

Write a chemical equation for the neutralization of aqueous acetic acid, CH3CO2H, with aqueous sodium hydroxide, NaOH, to give aqueous sodium acetate plus water.     A.  CH3CO2H (l)    +  NaOH (aq)            >     CH3CO2Na (aq)  +  H2O (l)   B.  CH3CO3H (aq)  +  NaOH (s)              >     CH3CO2Na (aq)  +  H2O (l)   C.  CH3CO2H (aq)  +  NaOH (aq)           >     CH3CO2H (aq)    +  Na2O (s)   D.  CH3CO2H (aq)  +  NaOH (aq)           >     CH3CO2Na (aq)  +  H2O (l)  

Calculate the molar mass for calcium phosphate, Ca3(PO4)2.

Use data for sugarcane bagasse from Table 4.6 in exam handout. It is proposed to construct a 50 MW CHP plant in a sugar refining facility. The power plant will use sugarcane bagasse with moisture content 35% (on wet weight basis) which is available at the facility as a waste product. The heat rate of the power plant is 13500 Btu/kWh. Calculate the annual sugarcane bagasse requirement (in metric tons as available or wet weight basis).

See Question 7 for background information. If ash fouling is a problem, raw coal is available to blend with sugarcane bagasse for use as a fuel for CHP plant. The raw coal, which contains virtually no alkali and no moisture has a heating value of 28 MJ/kg, sulfur (S) content of 4 % (by weight) and chlorine (Cl) content of 0.1 %(by weight). Calculate the minimum amount of coal that should be blended with sugarcane bagasse to prevent ash fouling.

What is the maximum number of electrons that can occupy the 3d energy sublevel?

Ammonium nitrate is used in explosives and is produced by the reaction of ammonia, NH3, and nitric acid. The equation for the reaction is                                    NH3 (g) + HNO3 (aq)    →    NH4NO3 (s) If 15.0 kg of ammonia gives an actual yield of 65.3 kg of ammonium nitrate, what is the percent yield? The calculated yield of ammonium nitrate for the experiment is 70.5 kg.
