In KCl, how are the valence electrons distributed? Question 13 options: A) The electrons are unequally shared between K and Cl, forming a polar covalent bond. B) The electrons are transferred from K to Cl. C) The electrons are equally shared between K and Cl, forming a covalent bond. D) The electrons are shared between many K and Cl ions, creating a "sea of electrons."

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
