C. 90 percent of us have recycled in the last year
A covalent bond is a bond in which electrons are shared. In an ionic bond, electrons are completely transferred. In this case phosphate ion (PO4)-3 is covalent which means that C and D cannot be the correct answer. Additionally, since the charge is on the oxygen atoms due to the bonding with phosphorus, we can say that the charge is on the entire ion and not just on the phosphorus atom. Therefore the answer is A.
Answer:
They form acidic solutions
SO2(g) + H2O(l) --> H2SO3(aq)
SO3(g) + H2O(l) --> H2SO4(aq)
Explanation:
Group 6 elements are elements on the periodic table with 6 atoms on their valence shell. Metallic properties increases down the group from oxygen through polonium. Examples are oxygen, polonium, sulphur etc.
Group 6 nonmetal oxides react with water to form acidic solutions, this is because the oxides of nonmetallic elements are basic in nature.
Sulphur exhibits a wide range of oxidation states ranging from +2 to +6. So its oxides are SO2 and SO3.
Example:
SO2(g) + H2O(l) --> H2SO3(aq)
SO3(g) + H2O(l) --> H2SO4(aq)
