Mass, like weight, always changes depending on its location.

A hot-air balloon is rising straight upward with a constant of 6.5 m/s. When the basket of the balloon is 20.0 meters above the ground a bag of sand comes loose.

How are electrons distributed in the molecular orbitals, when the 1s orbitals of two hydrogen atoms combine to form a hydrogen molecule?

Which of the following is a scale quantity?
