The value for ψ in root tissue was found to be -1.6 bars. If you place the root tissue in a 0.1 m solution of sucrose at 20°c in an open beaker, what is the ψ of the solution, and in which direction would the net flow of water be? (hint: remember your formula: ψs = -icrt & your pressure constant, r = 0.0831 liters bars/ m k)

In a spacecraft, the following reaction occurs: co2(g) + 2lioh(s) -> lico3(s) + h2o(i) (i attached picture of equation) how many liters of carbon dioxide will 4 moles of lithium hydroxide (lioh) absorb? (one mole of any gads occupies 22.4 l under certain conditions of temperature and pressure. assume those conditions for this equation.) 45l 6.0l 3.0l 34l
