water bugs use to float, and the A _ _ _ _ _ _ _ that allows it to climb I _ _ _ _ or P _ _ _ _ surfaces. H _ _ _ _ _ _ _ _ _ _ compounds dissolve by forming a S _ _ _ _ _ of H _ _ _ _ _ _ _ _. Fortunately, it is not a universal S _ _ _ _ _ _, since H _ _ _ _ _ _ _ _ _ _ compounds like N _ _ _ _ _ _ _ fats are insoluble. Relative to other Group 6A hydrides (H2S, H2Se, and H2Te), water’s B _ _ _ _ _ _ P _ _ _ _ and M _ _ _ _ _ _ P _ _ _ _, and the related molar or S _ _ _ _ _ _ _ H _ _ _s of V _ _ _ _ _ _ _ _ _ _ _ and F _ _ _ _ _, are much too high. This allows S _ _ _ _, that is water V _ _ _ _, clouds, F _ _ and S _ _ _ to exist on Earth. And do you know any other substance whose D _ _ _ _ _ _ decreases as it freezes so that _ _ _ floats? Water causes the H _ _ _ _ _ _ _ _ _ of complex molecules and polymers. And, finally, it can I _ _ _ _ _ to produce a hydroxide and a H _ _ _ _ _ _ _ _
