1 Forms of Water 2 • Water consists of an Water is a Polar Molecule oxygen atom bound to -has oppositely charged two hydrogen atoms ends by two single covalent bonds. – Oxygen has unpaired & paired electrons which gives it a slightly negative charge while Hydrogen has no unpaired electrons and shares all others with Oxygen – Leaves molecule with positively and negative charged 3 ends Water molecules form Hydrogen bonds slightly positive charge hydrogen

Water resources are sources of water that are useful or potentially useful. Uses of water include agricultural‚ industrial‚ household‚ recreational and environmental activities. Virtually all of these human uses require fresh water. 97% of the water on the Earth is salt water. However‚ only three percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps.[1] The remaining unfrozen freshwater is found mainly as groundwater‚ with only a small fraction present

The Biological Importance of Water Water is perhaps the most important molecule for the survival and life of organisms. On the surface of the planet there is obviously much more area of water than land‚ which shows its significance. The fact that water makes up 60-95% of all living organisms shows the incredible biological importance of water. Water has many uses and roles‚ one of them it being used as a support unit in plants. The uptake of water by plant cells creates a pressure against the rigid

Abstract: Water potential is the measure of free energy of water in a solution. The purpose of this lab was to find the water potential of a potato cell. The problem of this lab was‚ if there was a high molarity of solute‚ would it have a positive or negative water potential? The hypothesis of the experiment was‚ if there is a high molarity of solute then the water potential would be lower or negative. After obtaining potatoes‚ we cut them into pieces‚ weighed them‚ and then placed them in a solution

properties of water were tested and proved. These trials and experiments were able to verify the adhesion‚ cohesion‚ polarity‚ temperature stabilization‚ solvency‚ and density changes exhibited by water. During the glass and wax paper lab‚ we observed the adhesive properties of water. When a droplet of water touched the glass‚ it dispersed immediately. The droplet placed on the wax paper remained intact and in droplet form. Also‚ when the glass and wax sheets were flipped‚ the water remained on

Hi‚ my name is water molecule! H2O for short. I live in the bottom of a well. I come from 2 hydrogen atoms‚ but I have an oxygen atom in me! Down here in my well‚ we have a swell time together. In our liquid state‚ we are not too far apart‚ nor too packed together. It’s really great being a liquid! I feel bad for my cousin CO2. He is probably sublimating into a gas from a solid‚ or as a gas‚ freezing back into a solid. He has no melting point‚ only a freezing and boiling point. I’m SO glad I will

Conserving water can greatly limit the negative impact we have on the environment. By thinking conscientiously and creatively‚ we can make sure that everyone has enough water‚ while also minimizing the energy we use to bring it to our faucet or garden hose. Plus‚ using water wisely can lower many water bills. At Urban Times‚ it has been high on our agenda to bring more awareness to the increasing scarcity of water. This infographic‚ brought to us by Seametrics‚ illustrates that our water consumption is

Have you ever dropped oil on your hands and tried to wash it off? What happens? Does the water slide off? Or what about when a drop of oil falls in a glass of water? Why does it float to the surface‚ and not mix? The answer to this is simple: polarity. What exactly is polarity? A polar bond is when there is a difference in electronegativity‚ which means the tendency of an atom to attract a bonding pair of electrons. When two atoms are bonded together and one attracts more electrons‚ this results
