A way we can reduce disadvantages of human made materials is simply by finding new uses for them such as when plastic is molded and used for a container of a liquid.
(x-3)² = (x-3)(x-3)
= x² - 3x - 3x + 9
= x² - 6x + 9
The correct answer is B. Two oppositely-charged ions
Explanation:
In chemistry, ionic bonds only occur between ions oppositely charged, this means one of the ions has to be positively charged and the other has to be negatively charged. This is because there is a natural attraction between particles with different charges and this leads to the formation of chemical bonds. Also, this bond implies the transfer of electrons between ions. In this context, this type of bond can only occur with oppositely-charged ions. Moreover, particles with the same charges either negative, positive, or neutral do not experience attraction and cannot form ionic bonds.
