I did a lab by combining 5.0 mL of sodium hydroxide with 5.0 mL of copper sulfate (II) producing sodium sulfate and copper (II) hydroxide.The question on my sheet says this:Calculate the mass of the precipitate if 0.080g copper sulfate reacted with an excess of sodium hydroxide.
1) write bal. rxn.: 2 NaOH + CuSO4 ----- Cu(OH)2 + Na2SO4 2) calc. moles of CuSO4 formed 0.080 g CuSO4/ molec. wt CuSO4( g/mole) ? moles of CuSO4 3) from the bal. rxn., 1 mole of Cu(OH)2 is formed per 1 mole CuSO4 ? moles CuSO4 x molec. wt of Cu(OH)2 mass of Cu(OH)2 formed
And why is the air up there hot?
We have worked with numerous providers in the past and the below one is certainly the best. They have perhaps a great deal of unique air max contains uncommon types which you could not buy from other retail stores. The product quality and services is best that you can find online with such a cheap price. With this supplier, I bet you aren't going to disappoint you or your customers.
And why would you possibly need one? The airflow around a motorcycle is generally enough to keep the temperature going into the intake low, to start with. A cold air intake for it, would be utterly pointless. Assuming you knew how the physics of all this worked, and weren't just trying to buy something because it sounded cool, anyway
