Its a covalent bond formed by Potassium and Chlorine.
The product obtained is POTASSIUM CHLORIDE.
Hope this HELPS !!!
Because the speed of light is determined by the medium that is it in. If light is in a vacuum it goes 300 million meters per second but it is slower in air, and even slower in water because water is more dense than the previous two.

1 mL is much more precise than 100 mL because 1 mL is a very small and precise unit of measurement</span>
Answer:
Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions.
