What is the enthalpy of formation of CO(g) in kJ? 2CO(g) + O2(g) --> 2CO2(g). ?H reaction = -566 kJ ; ?H CO2(g) =-393.5 kJ/mol.
because the electronegative chlorine atom pulls electrons away from the O-H bond and thus weakens it. Calculate the hydronium-ion concentration and the pH of a 0.0022 M solution of chloroacetic acid. Ka is 1.3 10-3.
What is the difference between a hypothesis and a theory? a hypothesis is a proposal that has been tested extensively, whereas a theory is an initialy stated proposal a hypothesis is a conclusion made after a theory was tested words hypothesis
a natural hormone of moths has a molecular formula of C21H40(its a zero not an o) and yields the following three compounds on ozonolysis; (1) dodecanol
The absorption rate constant is smaller than the elimination rate constarnt. Therefore, the terminal decline of the plasma concentration versus time curve reflects absorption not elimination.
A 56.0 mL solution of phosphoric acid is neutralized by 136.0 mL of 2.6 M NaOH. What is the concentration of the acid?
Water vapor can be maintained at 100 oC and 2 atm pressure for a time; it will spontaneously revert to a liquid. calculate delta H, delta S, delta G for g->l. Assume vapor behaves ideally and liquid is basically imcompressible.
Determine the mass of this substance should evaporate in order to freeze 190 grams of water at 25 degree Celsius initially? It is given that the heat of fusion H 2 O= 334 specific heat of H 2 O= 4.18
If 4.00 g of the unknown compound contained 0.133 mol of C and 0.267 mol of H, how many moles of oxygen, O, were in the sample?
Write two equations for the dehydration of 2-methyl-2-butanol. One should show the structures of both alkenes, and the other one should be balanced.
1.90-g sample of a large biomolecule was dissolved in 23.0 g of carbon tetrachloride. The boiling point of this solution was determined to be 77.85°C. Calculate the molar mass of the biomolecule.
What is the smallest possible integer coefficient of S in the combined balanced equation and compute the final pressure in the tank if nothing else is altered in the surroundings.
