How does precipitation work in the water cycle? What causes condensation? Why does water move into the ground to create groundwater? Why does the level of water seem to not rise when salt is dissolved in water? Why does salt dissolve in water?
Why does oxygen have such a low solubility in water? Why are sand particles insoluble in water? What are the unique properties of water that make it so critical to life? How is the thermocline of a body of water identified? Why does sugar dissolve in water?
When comparing and discussing bottled water, TDS is often mentioned as a standard quality metric. TDS stands for "total dissolved solids" and measures the minerals, salts and organic compounds that naturally dissolve in water via contact through rock and other surfaces. It is measured in milligrams...
Does hexane dissolve in water? Polar solvents dissolve in one another. Nonpolar solvents dissolve in one another. This is the like dissolves like rule. Methanol dissolves in water, buthexane does not dissolve in water. Does Epsom salts conduct electricity? Epsom Salt didn't conduct electricity in...
Once, hydrogen peroxide dissolve in water, at acid media hydroxyl radical generate but atalkaline media it dissociate and decomposed. Do peroxide bubbles mean infection? When you dab hydrogen peroxide on a cut, that white, fizzling foam is actually a sign thatthat the solution is killing bacteria...
CO2 is made up of one carbon atom and two oxygen atoms. The atoms share electrons, but they don’t share those electrons evenly -- the oxygen ends of a CO2 molecule have a slight negative charge. Water molecules are attracted to these polar areas, allowing CO2 to dissolve in water. The...
Why does the dissolution of HCl(g) in water to form concentrated hydrochloric acid increase the change in entropy? What is the change in entropy when 0.646g of water decomposes to form hydrogen gas and oxygen gas at 298 K? 2H2O(l) -> 2H2(g) + O2(g) ; ?S ...
known as acid rain. A small portion of the acid rain is from natural sources-such as volcanoes-most of it is from the burning of the fossil fuels. SO2 and NO very easily dissolve in water and can be carried far by the current of the wind. They can become a part of the, rain, sl...
DbicycleSubmit Biochemical oxygen demand (BOD) is a measure of organic meterial present in water : BOD value less than 5 ppm indicates a water sample to be Arich in dissolved oxygen Bpoor in dissolve oxygen Chighly polluted Dnot suitable for aquatic life.Submit ...
water, the water molecules stay attracted to each other and don't bond with the non-polar molecule, which can't dissolve as a result. But when the non-polar molecule is placed in a non-polar solvent, all the non-polar molecules form weak bonds and the non-polar solute can dissolve. ...
