As a bond between a hydrogen atom and a sulfur atom is formed, electrons are
(1) shared to form an ionic bond
(2) shared to form a covalent bond
(3) transferred to form an ionic bond
(4) transferred to form a covalent bond

You exhale co2 which is produced during cellular respiration.  co2 combines with the water in your blood's plasma to make up one half of the body's most important buffer pair, carbonic acid.  the more physical activity you engage in, the more co2 your body is producing.  you can see this by putting some of the cabbage indicator in a glass and then blowing bubbles into it through a straw.  can you see a change in the color of the indicator?

Identify the lewis base in this balanced equation: fe3+ h2o fe(h2o)63+

Recognizing the properties of water water has a "bent" geometry. which explanation does not explain why? o water's oxygen has unbonded electron pairs that repel each other. water can form hydrogen bonds. electrons are evenly distributed in the water molecule. do ne
