What's a scientific inquiry

The overall reaction in the lead storage battery is: Pb (s) + PbO2 (s) + 2 H + (aq) + 2 HSO4 - (aq)  2 PbSO4 (s) + 2 H2O (l) Calculate the potential at 310 K for this battery when [H + ] = [HSO4 - ] = 4.5 M. At 310 K E o = 2.

The energy required to dissociate KF into neutral atoms is 498 kJ/mol. Given that the first ionization energy for K is 418 kJ/mol, calculate the electron affinity (in kJ/mol) for F. Show your work for all calculations.

What is the acceleration of a 3 kg rock that is thrown with a force of 18 N?

A hot air balloon is hovering in the air when it drops a 40 Kg food package to some lost golfers. If the package is dropped from an altitude of 500 m and air resistance can be neglected, how fast is the package moving when it hits the ground?
