This will depend upon which version of copper oxide you have - copper I oxide or copper II oxide. dug rui con j nua ma họ (Các) Nguồn: ffffffff. Examples: Fe, Au, Co, Br, C, O, N, F.     Compare: Co - cobalt and CO - carbon monoxide, To enter an electron into a chemical equation use {-} or e. To enter an ion specify charge after the compound in curly brackets: {+3} or {3+} or {3}. Zn has a 2+ charge. 1 0. According to this knowledge, powdered ZnO dissolves rapidly even at low acid concentration and at relatively low temperatures. Compound states [like (s) (aq) or (g)] are not required. ZnO + H2SO4 = ZnSO4 + H2O. ZnS + O2 + H2O = ZnO + H2SO4; FeS + HNO3 = NO2 + Fe(NO3)3 + H2O + H2SO4; NH3 + O2 = NO + H2O; Al + HNO3 = NO + H2O + Al(NO3)3; Cu + HNO3 = Cu(NO3)2 + NO + H2O; Recently Balanced Equations; Calculators. In many cases a complete equation will be suggested. 1 decade ago. SO4 has a 2- charge. Die traditionelle Bezeichnung Zinkweiß (Chinesischweiß, Ewigweiß, Schneeweiß) stammt von der Verwendung als weißes Farbmittel in Malerfarbe. Zinkoxid (ZnO) ist eine chemische Verbindung aus Zink und Sauerstoff, die einerseits farblose, hexagonale Kristalle bildet oder andererseits, aufgrund der Lichtbrechung bei sehr kleinen Kristallen, als lockeres, weißes Pulver vorliegt.. If you do not know what products are enter reagents only and click 'Balance'. Cu + H2SO4 --> CuO + SO2 + H2O. Ẩn danh. H has a 1+ charge .

ZnO nanoparticles (NPs) have been synthesized on porous silica microparticles, namely sand microparticles using the sol–gel technique. Anonymous. Zinc oxide react with sulfuric acid ZnO + H2SO4→ ZnSO4+ H2O [ Check the balance ] Zinc oxide react with sulfuric acid to produce zinc sulfate and water. The answer will appear below, Always use the upper case for the first character in the element name and the lower case for the second character. zinc oxide + sulphuric acid ---> zinc sulphate + water. Redoxreaktion ist ausgeglichen. 1 0. Anonymous. Empirical Formula Calculator; Molar Mass Calculator; Bond … The enhanced rate constant observed was due to two reasons. this is a substitution reaction. Substitute immutable groups in chemical compounds to avoid ambiguity. Eshna. Source(s): chem major. 5 years ago. ZnO + H2SO4 ---> ZnSO4 + H2O. zinc + sulphuric acid gives zinc sulphate + water <3. O has a 2- charge. 2 1. robin. 0 0. ZnO+H೭SO4→ZnSo4+H೭0(Zinc Sulphate+water) 0 2. Sulfuric acid - diluted solution. SO4 has a 2- charge. zinc + sulphuric acid gives zinc sulphate + water <3. Eshna .
