The balanced reaction that describes the reaction between hydrogen and oxygen to produce water is expressed 2H2 + O2 = 2H2O. Hence for each mole of oxygen used, two moles of hydrogen is used and two moles also of water is produced.
Answer:
See explanation
Explanation:
Air contains a mixture of several molecules and compounds such as oxygen and carbon dioxide.
Answer:
solid
Explanation:
When a solid is melted, for example, thermal energy is what causes the bonds within the solid to break apart.
Basically, electron donors are the elements that give up there electrons, so they will be oxidized. In the reaction, Zn(s) oxidizes into Zn^+2, so the 2 electrons are bing donated to the Cu^2+. Thus Zn(s) is the electron donor
