STEP 4. Next, pour 1 cup of warm water into each jar. A good scientist carefully measures so that all variables but one are the same. In this case, the amount of water is the same, but the material in each jar is different. Read more aboutvariables in sciencehere. STEP 5. Lastly,...
6.0 of ammonium phosphate is dissolved into water to produce 300mL of solution.What are the concentrations (in mol/L) of the ammonium ions and phosphate ions present?我是加拿大高中生.大概中文就是有6克(NH4)2PO4融化在300毫升水里,求nh4离子和po4离子的concentration. 答案 M[(NH4)3PO4] = 1...
Water is not only a powerful drink but also a universal solvent. As such, it has the ability to dissolve and absorb molecules from a number of substances. These dissolved particles in a volume of water are the total dissolved solids (TDS) level. TDS has two forms, organic an...
Distillation heats the water until it vaporizes. The vapor separates from dissolved minerals, suspended solids, and other impurities. Those remain in the original container, while the water vapor is captured elsewhere. The pure vapor is then cooled back to liquid water. Distillation removes minerals...
lower concentration of [H2O] than the distilled water. The water will then diffuse into your cell trying to make equal concentrations of [h2O] in both your cells and the water just consumed. This process is call osmosis. Your cell will burst trying to intake the large amount of water. ...

Many subsurface waters are considered groundwater but are influenced in shallow depths by hyporheic, parafluvial and/or soil interception water to such a degree that groundwater fauna (stygofauna) communities may be significantly altered. Recharge, even if spatially and temporally distinct, delivers ...
