how many L oxygen do I need in order to completely combust 1.56 kg of C3H10

When you strike a match on a matchbox you are reacting to potassium chlorate (KClO3)with Rex phosphorus (P4)to create tetraphosphorous decaoxide and potassium chloride.If I react 41.3g of potassium chlorate with 51.4 g of red phosphorus,find the mass of tetraphosphorous decaoxide will I produce,show the balanced equation ,find the limiting reagent,and show how much unused reactant I will have left over

If I combine iron(III)oxide with solid aluminum I create liquid iron and aluminum (III)oxide.If I want to create 19.5g of iron how much of each react would I need ?How much aluminum oxide would be created in this reaction

Methanol(CH3OH)can be manufactured by combining gaseous carbon monoxide and hydrogen gas.If I combine 9.13kg of carbon monoxide with 12.5kg of hydrogen gas show the balanced equation,find the limiting reagent ,and calculate how much product I’ll create.Finally show much unused reactant I will have left over.

Distinguish between e1 and e2,sn1 and sn2

The concentration of cholesterol dissolved in chloroform is 0.615g per 10ml of solution.A portion of this solution in a 5cm polarimeter tube caused an observation of -1.7, calculate the specific rotation of cholesterol?

Using structures only, list three examples of diastereomers, showing the different chirality centres as well as the possible stereoisomer?

Titrate the base trimethylamine (TMA) with 0.126 M HCl.

(CH3)3N(aq)+H2O(l)-->(CH3)3NH+OH Kb=6.45×10^5

There are .00615 moles of (TMA) in 42.5 mL H20 befor titration begins


a) write the Kb expression for TMA?

b) what is the pKb value?

c)what is the initial concentration of TMA in H20?

d) what is pH of the TMA solution before titration has begun?

e)what percent of TMA is in the protonated from at the beginning of the titration?

f) what volume HCl must be added to reach midpoint of the titration?

g) what is the total volume of buffer region?

h)what is the total volume of HCl added at the equivalence point?

I) what is the pH at the equivalence point?
