Identify the best explanation for which cation, lithium or sodium, has stronger ion-dipole interactions with water and why. Identify the best explanation for which cation, lithium or sodium, has stronger ion-dipole interactions with water and why. Since ΔHhydration of LiCl is more positive than for NaCl, LiCl has the stronger ion-dipole interactions. Since ΔHhydration of NaCl is more positive than for LiCl, NaCl has the stronger ion-dipole interactions. Since ΔHhydration of NaCl is more negative than for LiCl, NaCl has the stronger ion-dipole interactions. Since ΔHhydration of LiCl is more negative than for NaCl, LiCl has the stronger ion-dipole interactions.

Which of the following mining methods disrupts the sea floor?

Hot air balloons float in the air because of the difference in density between cold and hot air. in this problem, you will estimate the minimum temperature the gas inside the balloon needs to be, for it to take off. to do this, use the following variables and make these assumptions: the combined weight of the pilot basket together with that of the balloon fabric and other equipment is w. the volume of the hot air inside the balloon when it is inflated is v. the absolute temperature of the hot air at the bottom of the balloon is th (where th> tc). the absolute temperature of the cold air outside the balloon is tc and its density is ďc. the balloon is open at the bottom, so that the pressure inside and outside the balloon is the same. as always, treat air as an ideal gas. use g for the magnitude of the acceleration due to gravity.

How many liters of water vapor can be produced if 108 grams of methane gas (ch4) are combusted at 312 k and 0.98 atm? show all work. pls ! will mark as brainliest
