Be sure to answer all parts. When powdered zinc is heated with sulfur, a violent reaction occurs, and zinc sulfide forms:
Zn(s) + Sg(s) → ZnS() (unbalanced]
(a) Some of the reactants also combine with oxygen in air to form zinc oxide and sulfur dioxide.
When 83.2 g of Zn reacts with 52.4 g of Sg, 109.3 g of ZnS forms. What is the percent yield of ZnS?
%
(b) If all the remaining reactants combine with oxygen, how many grams of each of the two oxides
form?
Mass Zno:
g
Mass SO2:

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
