Draw the skeletal structure of 1-isopropyl-3-methylcycloheptane. Please explain, I am having trouble grasping this concept.
what are the H3O+ and OH- concentrarions in a 125 mL solution prepared with 0.100 mol pf NaOH and water?
Calculate the pH at the equivalence point for the titration of 0.25 M CH3COOH with 0.25 M NaOH. (For CH3COOH, Ka= 1.8 × 10^-5)

If the temperature is 22 degrees C, the total pressure in the tank is 3.50 atm, and the density of the gas in the tank is 1.17 g/L, what is the partial pressure of H2?
Water is 11.2% hydrogen and 88.8% oxygen by weight. If 75.5 grams of hydrogen are produced by decomposing water, how many grams of water were decomposed and how many grams of oxygen were produced
How is the equilibrium yield of C6H12O6 affected by each of the following? 6 CO2(g) + 6 H2O(l) + HEAT C6H12O6(s) + 6 O2(g) (a) increasing PCO2 increases decreases no effect
The molar heat of neutralization from hydrochloric acid and sodium hydroxide is -57.3 kJ/mol. use this accepted value to predict the heat evolved
A precipitate again formed and was filtered off. Finally, the solution was treated with a sodium carbonate solution, which resulted in no precipitation. Which metal ions were definately present, which were definately absent, and which may or may n..
