The government wants to set new regulations that prohibit chlorofluorocarbons (cfcs) use in aerosol sprays and refrigerants. how will this act with the sustainability of our environment? . a) it will increase the costs of aerosol sprays and refrigerants. b) it will increase ultraviolet light needed for vegetation. c) it will slow the degradation of the ozone layer. d) it will decrease the use of fossil fuels.

It will slow the degradation of the ozone layers

Explanation:

I took the test and it was correct

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.
