A chemist adds of a potassium dichromate solution to a reaction flask. Calculate the mass in milligrams of potassium dichromate the chemist has added to the flask. Round your answer to significant digits.

In a reaction (at equilibrium) that makes more moles of gas than it consumes, what is the effect of increasing the pressure?

Amixture with the same composition throughout is!

For the reaction c6h14(g) & longrightarrow; c6h6(g) + 4h2(g), δp(h2)/δt was found to be 2.5 x 10-2 atm/s, where δp(h2) is the change in pressure of hydrogen. determine δp(c6h14)/δt for this reaction at the same time.
