Calculate the change in internal energy (ΔE) for a system that is giving off 35.0 kJ of heat and is changing from 21.00 L to 15.00 L in volume at 1.50 atm pressure. (Remember that 101.3 J = 1 L∙atm)

What is the solubility of substance?

20 pts ‼️ an unmanned spacecraft travels to mars. mars has a lower strength of gravity than earth. where in the image is the spacecraft’s weight the greatest?

Substance a is a nonpolar liquid and has only dispersion forces among its constituent particles. substance b is also a nonpolar liquid and has about the same magnitude of dispersion forces among its constituent particles. when substance a and b are combined, they spontaneously mix.
