Zinc metal can be obtained from ZnO, by reaction at high temperature with CO, ZnO (s) CO(g) ->Zn(s) CO2 (g) The carbon monoxide (CO) is obtained from reaction; C (s) O2(g) -> CO(g) If 68.0g ZnO and 13.0g O2 were used, how many grams of Zinc would be produced

Any photo? or something

The correct answer should be "electrons orbit the nucleus in circular motions exactly as shown on the classic bohr model."

Order of filling levels and sublevels of electrons: 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s²3f¹⁴5d¹⁰6p⁶for an element with 5 electrons in the 3d energy level: full configuration: 1s²2s²2p⁶3s²3p³.

In reversible reaction chemistry equilibrium is attained when the forward and reverse reactions are taking place at the same rate, thus, the concentrations of reactants and products remain the same. a reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. in irreversible reactions on the other hand, the reactants react to form the products, which cannot revert back into reactants.
