Kim Pupil performed this experiment and prepared a plot of lnP versus 1/T with a temperature scale ranging from 1/273 K to 1/353K. Fran teacher penalized Kim 10 points. what was wrong with Kim's graph?
What is the solubility in moles/liter for copper(II) iodate at 25 oC given a Ksp value of 1.4 x 10-7. Write using scientific notation and use 1 or 2 decimal places (even though this is strictly incorrect!).
The normal freezing point of water H2O is 0.00 oC and its Kf value is 1.86 oC/m. Assuming complete dissociation of the electrolyte,
Which of the following will not have ionic bonds?
Write down the product for the reaction; Butane (forward and backward reaction)in the presence of Aluminium bromide and HBr at the temperature of 27 degree celcius/
how many moles can be produced from 2.5 moles of Ag2CO3 and final temperature of the calorimeter contents is 23.83°C After dissolution of the salt.
Therefore the formula is N2O4 Dinitrogen tetraoxide. Recognizing Incorrect Names and Formulas of Explain what is wrong with the name of formula in the second.
