Predict the number of regions of electron density (domains) around the central atom in the ion of CO32- . And predict the hybridization of the central atom.

What pressure is exerted on a 20.0L container with 15.9 g of SO2(s) at a temperature of 25.0 °C ?

Calculate:  (6.022 x 10 23 ) / 6.324 There is only one correct answer.  One of the routine calculation in CHM2045 involves power of 10.  Note: read your calculator’s instruction to learn how to type in power of 10.   

Determine the mass of the following compound: 0.0146 mol KOH

Considering the limiting reactant concept, calculate the number of moles of CO2 produced from 2.80 moles of O2 and 0.700 moles of C2H6 by the following reaction. 2C2H6(g) + 7O2(g) → 4CO2(g) + 6H2O(g)

Calculate:  -4.372 x (2.342/15)  There is only one correct answer.  One of the routine calculation in CHM2045 is multiple-step addition/subtraction and multiplication/division.   If you can’t get the correct answer for the first time, retake this quiz, you have unlimited attempts.
