Car manufacturers have begun to explore the use
of biofuels, such as biodiesel, ethanol, and cooking
oils made from plant material. the desired
outcome of using these biofuels would be
(1) a decrease in the use of fossil fuels
(2) a decrease in the release of oxygen gas
(3) an increase in abiotic resources
(4) an increase in global warming

good luck

explanation:

i still can't find this

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
