To tell if CuSO4 (Copper (II) sulfate) forms an acidic, basic (alkaline), or neutral solution we can use these three simple rules along with the neutralizati. [1] Wikibooks, General Chemistry/Properties of Matter/Changes in Matter. To balance a chemical equation, every element must have the same number of atoms on each side of the equation. The law of conservation of mass says that matter cannot be created or destroyed, which means there must be the same number atoms at the end of a chemical reaction as at the beginning. Write the state (s, l, g, aq) for each substance.3. The balanced equation will appear above. There are two cations (Cu2+, H+) around cathode. Balance the equation NaOH + CuSO4 = Na2SO4 + Cu(OH)2 using the algebraic method or linear algebra with steps. concentration become very low, H+ ions are reduced to H2 molecules. Step 1: Calculate amount of copper plating on the Iron spoon, Step 2: Decide how much electrons are exchange when Cu2+ are reduced to Cu. Does the 500-table limit still apply to the latest version of Cassandra? rev2023.4.21.43403. You might well be correct, but energetically to lose four strongly bound waters before losing one other one does not seem to be what one would expect. Therefore, there should be enough The resulting matrix can be used to determine the coefficients. The reaction is the reverse of the cathode reaction. This happens for instance in items made of metals above copper in the reactivity series. Are there any canonical examples of the Prime Directive being broken that aren't shown on screen?
