BaSO4 does not react with NaOx, so there is no chemical reaction equation. Both of them did not have the conditions for metathesis and oxido-reduction reactions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction equation between BeOx and NaOx was: Be(Ox) 2 + 2NaOx = Na 2 BeO 2 + 2H 2 O. Besium hydrogen was an amphoric hydrogen dioxide, which could react with both strong acid and strong base, so it could react with the above reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Sulphite and sulfuric acid will react, and the reaction equation is: when sulfuric acid is insufficient, SO32- + H+ = HSO3-; when sulfuric acid is excessive, SO32-+2H + = SO2 Qianqian + H2O. Sulphite ion was a kind of acid radical ion with the chemical formula of SO32-. It had a triangular cone structure, and the central sulfur atom adopted sp3 hybrids. It was a weak acid radical and had strong reducing properties. Sulfite will be converted into sulfuric acid ions in the acidic nitrates solution, which can form white sulfuric acid deposits that are not dissolved in strong acid with the formation of sulfuric acid. It cannot react with the solution of sulfuric acid (because sulfuric acid can be dissolved in strong acid). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
When the iron reacted with the copper sulfuric acid solution, the iron could replace the copper from the copper sulfuric acid because the iron was more active than the copper. The reaction equation was: FeSO2 = FeSO2 + Cu2, and the reaction phenomenon was that a red solid was separated from the iron surface. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
It wouldn't react because the elemental valences of copper dioxide and mercury dioxide were stable. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
If it was a reaction between pure aluminum and aluminum, the gas produced would be H <2>, which had no smell. If there was a pungent smell, it might be because there were impurities in the used soda. In addition, the aluminum nitrogen in the aluminum ash can react with water to produce a pungent odor of hydrogen. If there are aluminum nitrogen impurities in the soda solution, an unpleasant smell may appear during the reaction with aluminum. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction between the two reagents was: 2Fe3 ++3S2- = 2Fe2 ++3S. Iron ions are ions formed after iron loses three electrons. They are relatively stable and have a strong oxidisation property. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The chemical equation of the reaction is: SnO + CuSO4 + H2O = CuSO4 + CuSO4. The principle of the reaction was that copper ions were produced by the decomposition of copper ions into hydrogen ions, which then reacted with the metal. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Chromium-copper sulfuric acid solution can react, and the chemical equation of the reaction is 2Cr +3CuSO4 == Cr2(SO4)3 + 3Cu. In this reaction, the Chromium-copper solution is oxided to +3. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The two didn't react. One was a strong acid and a weak base salt, and the other was a weak base, which didn't meet the conditions for the metathesis reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
