Water, pH and Macromolecules A compound that is capable of forming hydrogen bonds with water contains at least some polar covalent bonds is probably held together by noncovalent bonds should act as a good buffer for acids and bases does not dissolve well in water contains at least some polar covalent bonds is probably held together by noncovalent bonds should act as a good buffer for acids and bases does not dissolve well in water ANSWER DOWNLOAD EXAMIANS APP
Water, pH and Macromolecules Salt dissolves well in water as water molecules share electrons with the ions to make polar covalent bonds surround the ions because of their charge but do not form hydrogen bonds make nonpolar covalent bonds with the positively charged ions only form hydrogen bonds with the positively and negatively charged ions share electrons with the ions to make polar covalent bonds surround the ions because of their charge but do not form hydrogen bonds make nonpolar covalent bonds with the positively charged ions only form hydrogen bonds with the positively and negatively charged ions ANSWER DOWNLOAD EXAMIANS APP
