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?

Consider the reaction: n2(g) + o2(g) ? 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?

If 1.8 l of water is added to 2.5l of a 7.0 m koh solution, what is the molarity of the new solution

Avariable that is not being directly tested during an experiment should be changed varied experimented controlled
