3 covalent bonds (there are 2 electrons in the first orbital and 5 in the second. You still have room for three more)
The answer is D: Products combine to produce new reactants... Hope this helps! :)
It is called a waxxing gibbous, pls brainliest
2ZnS(s)+3O2(g) -> 2Zns(s) + 2SO3(g)
the above given equation is unbalanced as it contains 4 moles of sulphur in the output but in the input there are only two aoms of sulphur so to balance the equation we will write the equation as given under
balanced equation is
2ZnS(s)+3O2(g) -> 2Zn(s) + 2SO3(g)
In words:
When 2 moles of solid zinc sulfide reacts with 3 moles of oxygen gas gives 2 moles of solid zinc and 2 moles of sulphur trioxide gas.
An endothermic reaction is when the energy is absorbed, while an exothermic reaction releases energy.
