Curve to the currence of these discontinues 33 which form of sal will be stable at a soluty of 75 kg of nahpo. 100 g 3 0 kg of water is added to a beaker containing 150 kg of foso. and continuous ed to prepare a solution at 57°c (use figure 51) 561 what type of solution (saturated, unsaturated, supersaturated) will be present at this temperature? 542 the temperature of the solution is suddenly reduced to 47"c. what type of solution (saturated, unsaturated, supersaturated) will be present at this temperatura?

In a laboratory experiment, a fermenting aqueous solution of glucose and yeast produces carbon dioxide gas and ethanol. the solution was heated by burning natural gas in a bunsen burner to distill the ethanol that formed in the flask. during the distillation, the ethanol evaporated and then condensed in the receiving flask. the flame of the burner was kept too close to the bottom of the flask and some of the glucose decomposed into a black carbon deposit on the inside of the flask. during this experiment the following changes occurred. which of these changes involved a physical change and not a chemical change? check all that apply. 1-condensation of ethanol 2-evaporation of ethanol 3- formation of carbon dioxide gas from glucose burning of natural gas 4-formation of ethanol from glucose by yeast 5-formation of a carbon deposit inside the flask

What is the temperature of one mole of helium gas at stp?

A5 mole sample of liquid acetone is converted to a gas at 75.0°c. if 628 j are required to raise the temperature of the liquid to the boiling point, 15.600 kj are required to evaporate the liquid, and 712 j are required to raise the final temperature to 75.0°c, what is the total energy required for the conversion?
