Two different gases occupy two separate bulbs. (Figure 1) Consider the process that occurs when the stopcock separating the gases is opened, assuming the gases behave ideally. Part A Predict the sign of ΔH for the process. Predict the sign of for the process. ΔH > 0 ΔH < 0 ΔH = 0 Part B Predict the sign of ΔS for...
In the Challenge Solution, the introduction of GM seeds shifts the market supply curve to the right and the market demand curve to the left. In turn, we could predict the change in the equilibrium price of crops but not the equilibrium quantity. Are there any conditions on the shapes of the supply and demand curves (or their elasticities) such...
how do you predict equilibrium? 5. Predict the position of the equilibrium for each of the following reactions: O-H a) (b e Li +H2C-CH b) H2C-CH Lit , bauag HCC CH + Na°NH 0 wd H&CC CNa c) NH3 + CCI,CO2 Na + CH,CO-Н + CHCO2Na+ Cl,CCO,Hd d) 0sH (s CH,O'Na -O-H + -O'Na +CH20-H == e) 5. Predict the...
The accompanying data are the number of wins and the earned run averages (mean number of earned runs allowed per nine innings pitched) for eight baseball pitchers in a recent season. Find the equation of the regression line. Then construct a scatter plot of the data and draw the regression line. Then use the regression equation to predict the value...
A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The cylinder has a piston that moves in or out, as necessary, to keep a constant pressure on the mixture of 1 atm. The cylinder is also submerged in a large insulated water bath. (See sketch at right.) 1 atm pressure...
OTHERMOCHEMISTRY Understanding the definitions of heat and work Lauren 1 atm pressure A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The cylinder has a piston that moves in or out, as necessary, to keep a constant pressure on the mixture of 1 atm. The cylinder is also submerged in...
