High-purity benzoic acid (C6H5COOH; delta H rxn for combustion= -3227 KJ/mol) is used as a standard for calibrating bomb calorimeters. A 1.221-g sample burns in a calorimeter (heat capacity= 1365 J/degrees Celsius) that contains exactly 1.570 kg of water. What temperature change is observedc
1 mole of monoatomic ideal gas is initially at T=300K, V=10L. Calculate w, q, deltaU, deltaH, deltaS, and delta S(surr) when the gas is expanding adiabatically against a constant external pressure p(ex) = 1 bar to a final volume of 20 L.
What is the product of the reaction. It always seems to lose format after I post. The the CH3 is attached to the last CH. and CH3I (excess) is suppose to be above the arrow.
When heated, all metallic hypochlorites decompose and produce oxygen. Considering this, what happens when the decomposition reaction occurs at an incident involving fire? Please reference your answer and tell me why.
What are the other side products present in this biocatytic reaction?
Determine the molarity of a solution of twenty grams of Ammonium bromide, NH4Br, in enough water to produce 132 mL of solution?
The atomic orbitals of two iodine atoms combine to form the diatomic molecule. Use the periodic table to determine the atomic orbitals that overlap to form the molecule and the symbol of the noble gas that has the same electron configuration as th..
Write a suitable mechanism for the cleavage of butyl isopropyl ether with HI at 100 degrees Celsius to form exclusively isopropyl alcohol and 1-iodobutane.
If 5.0 g of H2 are reacted with excess CO, how many grams of CH3OH are produced, based on a yield of 86%? CO(g) + 2H2(g) -> CH3OH(l)
Plot the absorbance against the ration of moles of X to moles of M. Calculate the formula of the complex from the mole ratio at which the absorbance reaches a maximum and levels off.
A chemist must dilute 71.4mL of 296mM aqueous potassium dichromate (K2Cr6O7) solution until the concentration falls to 81.0mM . He'll do this by adding distilled water to the solution until it reaches a certain final volume. Calculate this final ..
An open end manometer constructed from a U-shaped tube was operated using an oil which has a density of 1.088 g ml-1. In a particular measurement, the level in the end connected to the gas manifold, on which the experiment was being conducted,
A mixture containing 2.37 g each of CH4(g), C2H4(g) and C4H10(g) is contained in a 1.50 L flask at a temperature of 45°C.
