It oxidized cu since it gains electons.
For this item, we will have a double-replacement reaction. This means that the compounds will exchange elements. The balanced chemical reaction is shown below.
NaCH3COO + HCl --> NaCl + CH3COOH
So, what are formed in the reaction is the salt NaCl and the carboxylic acid, acetic acid. Hence, the precipitate formed is the salt NaCl.
Answer:
B. Solvent
Explanation:
In osmosis, water always moves from low solute concentration to high solute concentration. SOLUTE NEVER MOVES AS IT CANNOT PASS THE SELECTIVELY PERMEABLE MEMBRANE. alot of caps but need to stress this concept cuz otherwise this concept gets very confusing
Well, keep in mind q=msΔT, and that in these sorts of questions, -msΔT = msΔT (meaning that the energy lost by the metal as it cools down is gained by the water as it heats up).
If you put something hot into something cold, what happens? The hot metal would cool down, while the water would heat up, and given some time, both the metal and water would be at the same temperature. The metal would have cooled down, while the water would have heated up.
Answer:
Silver react with sulfuric acid to produce silver sulfate, sulfur dioxide and water.
