need help with the questions the arrows are pointing at SQ 3-The balanced chemical equation for the reaction of sodium bicarbonate and citric acid is below. 3 NaHCO3(aq) + C6H807(s) → Na3C6H5O7(aq) + 3H₂O(l) + 3CO2(g) = SQ 4-Write the Lewis Structure for all species in the net ionic equation. Reactants: Products: K SQ 5-Circle the bonds that are broken in the reactants and the bonds that are formed in the products.

Part II: Binary Covalent Compounds Covalent compounds are produces by nonmetals bonding with one another. You can use the valence electrons for each element to determine the simplest formula that exists between two elements. For example, H has 1 valence electron and needs one more to obey the Octet Rule, so it will only make 1 bond when found in a compound. Oxygen has 6 valence electrons and needs two more to obey the Octet Rule, so it typically makes 2 bonds when found in a compound. Since hydrogen needs just one electron while oxygen needs two, the correct formula for the simplest compound would be H20. However, there are often other combinations possible in addition to the simplest formula. For example, hydrogen and oxygen can also form, H2O2, which is known as hydrogen peroxide. To work with all the possible combinations, some rules have been developed for naming binary covalent compounds. The rules are stated below: 1. The least metallic element will always end in the suffix…
