Sulfur dioxide can be produced in the laboratory by the reaction of hydrochloric acid and sodium sulfite. The skeleton equation for this reaction is: Na2SO3 + HCl --> NaCl + SO2 + H2O
What mass of SO2 can be made from 25g of Na2SO3 and 22g of HCl?
The density of a gaseous element at 310oC and 1.02 atm is 2.64 g/L. What is the molecular weight of the element
What volume of CO2 gas is produced by the complete combustion of 2.6L (C3H8) gas? Assume all gas volumes are measured at the same temperature and pressure. C3H8 + 5O2 ---> 3CO2 + 4H2O
Assume that the complete combustion of one mole of ethanol to carbon dioxide and water liberates 1370 kJ/mol (?G°\' = -1370 kJ/mol). If the energy generated by the combustion of ethanol is entirely converted to the synthesis of a hypothetical comp..
a hydrocarbon with an empirical formula CH2 has a density of 1.88 grams per liter at 0 degress C and 1 atm. What is a possible formula for the hydrocarbon?
In the reaction 4 P4 + 5 S8 -> 4 P4S10 600 g of P4 is mixed with 1300 g of S8.
The normal boiling point of bromine is 58.8°C. Given that the vapor pressure of methanol is 75.0 torr at 2.5°C, calculate the molar enthalpy of vaporization of bromine.
Suppose that you are carrying out a dehydrohalogenation reaction on 2-bromo-2,3-dimethylpentane to yield alkenes
What liquid is insoluble in water and soluble in cyclohexane and alcohol; and has a boiling pint of 58 degress Celsius at 670 mm Hg.
The energy from condensing steam water is used to melt ice at 0 degrees Celsius. How much ice can be melted by condensing 1.0 kg of H2O vapor? (Delta H fus of ice= 6.01 kj/mol) (Delta H vap of water = 40.7 kj/mol)
Draw the first mechanistic step( one intermolecular arrow and any subsequent intramolecular arrows needed to finish the mechanistic step) between caffeine and hydrochloric acid.
what are the rates of production of P4 and H2 in this experiment?
Consider all the valence electron pairs of the central atom-both those that are shared in covalent bonds, called bonding pairs, and those that are unshared, called non-bonding pairs or unshared pairs.
