You add 1.5 moles of HF to 6 liters of water. The concentration is at equilibrium when [H+] is at 0.10 M what is the Ka of HF? HF-> H^+ + F^-

0.10

0.067

1.5

0.25

The density of water is 1 g/cm cubed and in order for the pebble to sink its density has to be greater than the density of water and in order for the twig to float its density has to be less than the density of water

Polymerization reaction

It starts to rust i think
