Ions are atoms with a charge other than zero. In a neutral atom, the number of protons (positively charged particles) in the nucleus equals the number of electrons orbiting the nucleus.
Atoms can gain or lose electrons (not protons) resulting in a net charge other than zero. Atoms which lose electrons (usually metals) become positively charges, and atoms which gain electrons (usually nonmetals) become negatively charged.
I think The answer to two is it would sink
Answer:
165 g
Explanation:
Law of Conservation of Matter states that neither matter or energy is destroyed but instead transferred.
Since we need a total of 180 g, we need to subtract 15g of one of the products to find the missing amount:
180 g - 15 g = 165 g Cu produced
The answer is B since it's a second order reaction.
