Bromine is a reddish-brown liquid. Calculate its den-sity (in g/mL) if 650 g of the substance occupies 188mL.
The equation for the reaction o KHP and NaOH shows ratio 1:1 ratio for the two reactants. Experimentally ,how do you know that base solution that you delivered from the burette had just as many moles as were in the KHPsample that you weighed out i..
Consider a 53.5 g sample of H2O(g) at 117°C. What phase or phases are present when 134 kJ of energy is removed from this sample.
does it mean that the solution will shift towards the products because there is excess of reactants? what does it mean when the solution is orange (is it shifting towards products or reactant)?
Draw the bondline structures of the isomers of this compound in the manner requested: Its diastereomer C, its optically active isomer D.
Determine the correct formula for this compound; use the "rule of 13" and substitute in O's and N's to generate the possible formulas (ie do not simply use online software to do this problem).
