One side of a plane wall is held at 200°c while the other side is exposed to a convective environment having t10°c and h 100 w/m2 °c. the wall has a k - 2.6 w/m °c and is 30 cm thick. calculate the heat flux through the wall. what is the temperature on the surface of the cold side of the wall? (remember this wll come up frequently later in the course.)

1.aluminum chloride (alcl3), and sodium hydroxide (naoh) can react to form aluminum hydroxide (al(oh)3) and sodium chloride (nacl).    you have 13.4 g of aluminum chloride and 10.0 g of sodium hydroxide. answer the following questions: •what is the balanced equation for this reaction? •if you use all 13.4 g of aluminum chloride, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •if you use all 10.0 g of sodium hydroxide, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •how many grams of aluminum hydroxide will actually be made?     which reagent is limiting? explain your answer.
