If an assay of soda ash sample was reported as 65.21% Na2CO3. Explain what the percent of carbon dioxide and carbonate ion?
1.an unknown gas has a mass of 1.36 kg and occupies a volume of 0.628cubic meters at 198 kpa and 35oc. determine the
A student is asked to react 3-methyl-2-butanol with HBr. predict the products and explain why the experiment will not be as successful for production of an alkyl bromide as the reaction of 1-butanol with HBr
Even though butanols have the same number of the same atoms, we see large differences in their ability to dissolve water. How do you account for this? How might you account for the much smaller differences observed among the pentanols
For the neutralization reaction involving HNO3 and Ca(OH)2, how many liters of 1.55 M HNO3 are needed to react with 45.8 mL of a 4.66 M Ca(OH)2 solution.
The decomposition of 3.32 g CaCO3 yields 1.24 g CaO. What is the percent yield of this reaction? CaCO3(s) -> CaO(s) + CO2(g)
What is the ph change of a 0.300 M solution of citric acid (pKa=4.77) if citrate is added to a concentration of 0.130 M with no change in volume
effuse through a membrane. How long would it take the same number of moles of Ar(g) to effuse through the same membrane?
what would be a procedure to go by for the reaction of 2 methyl 2 octene with Hbr and what solvents could be used
sodium bicarbonate is often used as an antacid to neutralize excess hydrochloric acid in an upset stomach. how much
Why is it particularly important to wash the cupric hydroxide intermediate in the synthesis of cupric acetate (verdigris)? Be specific about what is being removed and why it matters.
Determine the molar mass of carbon dioxide by measuring the mass of an Erlenmeyer flask full of the gas. The following calculations are intended to familiarize you with the general procedure:
What is the average rotational energy assuming that only J=0 to 4 levels are populated in the vibrational ground state n=0?
