If 50.0 g h2o at 13.6 c is combined with 85.0 g h2o at 93.7 c, what is the final temperature of the mixture? the specific heat capacity of water is 4.184 j/g·k.

Rethink and reinvent

Replicate prove reliability and validity

The disturbance is only parallel to the motion of the wave.

So the main goal for the elements is stability which is a complete/full valence shell and typically the magic number for a stable element is 8 valence electron but not always. so elements to the left of the periodic table tend to be way less stable then those on the right, so the elements on the left are much more reactive.
