Write the balanced equation, then outline the steps necessary to determine the information requested in each of the following
a) the number of moles and the mass of Mg required to react with 5.00 g of HCl and produce MgCl2 and H2
b) the number of moles and the mass of oxygen formed by the decomposition of 1.252 g of silver(I) oxide.
c) the number of moles and the mass of magnesium carbonate, MgCO3, required to produce 283g of carbon dioxide. (MgO is the other product)
d) the number of moles and the mass of water formed by the combustion of 20.0 kg of acetylene, C2H2, in an excess of oxygen
e) the number of moles and the mass of barium peroxide, BaO2, needed to produce 2.500 kg of barium oxide, BaO (O2 is the other product)
The preliminary concentration for iodine is 0.08 mole, if the reaction rate at this concentration was 36 seconds. Explain what would the reaction rate be if the concentration of iodine is doubled to 0.16 mole
How would excess solvent affect the melting point. How will impurities affect the melting point.
In each of the following groups of substances, pick the one that has the given property. Explain your reasoning for each.
If the mass of water surrounding the calorimeter was exactly 1000 g and the heat capacity of the bomb calorimeter without the water was 1.75 kJ/degrees Celsius, calculate the molar heat of the combustion of methanol
The bond distance and dipole moment calculated for the highly reactive gas phase OH molecule are 0.98Ao and 1.78D, respectively. Compute the effective charges on the O and H atoms of the OH molecule (in units of the electronic charges).
Draw all steroisomers of pentane-1,2,3,4,5, pentaol using bold and hashed wedges. There should be two meso compunds and a pair of enantiomers.
describe that means you have to write in detail how to prepare an aqueous 5.0 f solution of acetic acid ch3cooh. you
When trying to separate benzoin and 1,4-dibromobenzene we used hot methanol as the solvent. When the solid had dissolved, it was cooled in an ice bath until precipitate formed and then centrifuged in a craig tube. Would the 1,4-dibromobenzene prec..
A solution of HCl in water conducts an electric current , but a solution of HCl in hexane does not. explain this behavior in terms of ionization and chemical bonding
Predict any precipitates that are formed when the following solutions are mixed and give the net ionic equation. Ba(NO3)2 solution and KOH solution.
You have given some solutions as A. O.6MNH3 b. 0.150MKOH c. 0.100M Ba(OH)2 you just need to determine that which of the given solution is the most basic also give explanation for your answer?
Problem- Cumene is known to cantain only hydrogen and carbon. The burning of a sample of cumene produced .320 moles of co2 and .215 moles of water. What is the empirical formula
