Water, pH and Macromolecules Which of the following statements about covalently bonded molecules is false? The chemical bonds that hold the molecule together are relatively strong Such molecules often result from the interaction of ionized atoms Electrons are shared between the atoms that make up the molecule Noncovalent bonds may also be present, especially if the molecule is large The chemical bonds that hold the molecule together are relatively strong Such molecules often result from the interaction of ionized atoms Electrons are shared between the atoms that make up the molecule Noncovalent bonds may also be present, especially if the molecule is large ANSWER DOWNLOAD EXAMIANS APP
Water, pH and Macromolecules Salt dissolves well in water as water molecules surround the ions because of their charge but do not form hydrogen bonds share electrons with the ions to make polar covalent bonds form hydrogen bonds with the positively and negatively charged ions make nonpolar covalent bonds with the positively charged ions only surround the ions because of their charge but do not form hydrogen bonds share electrons with the ions to make polar covalent bonds form hydrogen bonds with the positively and negatively charged ions make nonpolar covalent bonds with the positively charged ions only ANSWER DOWNLOAD EXAMIANS APP
