Mr Z is building a greenhouse at his house to protect his plants from all the bugs that live in his garden. He is at Bunnings purchasing his materials and can’t decide whether to construct his greenhouse out of glass or tin. What information does he need to know to help him with this decision?

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther

explanation:

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.
