The answer is b. as a whole, the species is mutually beneficial to carry on each others traits and exist in the same ecosystem.
valence electrons are the number of electrons in the outer shell. there can only be 8 electrons in the outer shell. The number of valence electrons can be used to determine how many bonds are needed.
For example: H2O
O (oxygen) has 6 valence electrons
H (hydrogen) has 1 valence electron
O needs 2 more electrons to be stable
H needs 1 more electron to be stable
O forms one bond with two H atoms to form H2O.
Answer:
because the product of CuO contains 2 molecules so it is unbalanced
Explanation:
to balance it 2Cu+2O=4CuO now it is balanced
