Question- The compound known as butylated hydroxytoluene, abbreviated as BHT, contains carbon, hydrogen, and oxygen. A 2.001 g sample of BHT was combusted in an oxygen rich environment to produce 5.995 g of CO2(g) and 1.963 g of H2O(g). Insert subscripts below to appropriately display the empirical formula of BHT.
Please take care to answer each question mark in the equations
When 1.3584 g of sodium acetate trihydrate was mixed into 100.0 cm3 of 0.2000 M HCl(aq) at 25oC in a solution calorimeter, its temperature fell by 0.397oC on account of the reaction
The nitrogen in a 4-tablet sample that weighed a total of 7.50 g was converted to ammonia by Kjeldahl digestion, followed by distillation into 100.0 mL of 0.1750 M HCl. The analysis was completed by titrating the excess acid with 11.37 mL of 0.108..
What is the enthalpy of this reaction? Assume that no heat is lost to the surroundings or to the coffee cup itself and that the specific heat of the solution is the same as that of pure water.
The enthalpy of vaporization of water is 40.67 kJ/mol, the enthalpy of fusion for water is 6.01 kJ/mol, the molar heat capacity of liquid water is 75.4 J/(mol.C)
Consider the following element combinations. Classify the bonds formed between each pair as ionic, polar covalent, or nonpolar covalent based solely on each element's position on the periodic table: P-P, Ca-O, Al-N, O-Br, S-Br, F-F, P-Cl, Cs-Cl
