When using the Dumas method to determine the molar mass of a volatile material, a student fails to wipe off the outside of the test tube. What will this do to their calculations? A. The calculated Molar Mass will be too high.

B. The calculated Molar Mass will not be affected.

C. The calculated Molar Mass will be too low.

How many grams of co(g) are there in 74.5 ml of the gas at 0.933 atm and 30o c?

Liv sheldon given the balanced equation for an organic reaction: c2h2 + 2cl2 → c2h2cl4 this reaction is best classified as *

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
