How many grams of CuSO4 are there in 235 g of an aqueous solution that is 2.50% (w/w) ?

Ajet plane is speeding down the runway during takeoff. air resistance is not negligible. identify the forces on the jet.

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.

Why is the bottom layer of a trophic pyrimid the
