Answer:
decomposition is the answer it helped also explanation of it is below this answer
Explanation:
In a decomposition reaction, one reactant breaks down into two or more products. This is the reverse of a synthesis reaction. Replacement reactions occur when elements switch places in compounds

Answer:
, , ,
Explanation:
The four most abundant minerals in the continental crust are, , , , .
The percentages are
is called quartz
is called corundum
is called calcium oxide or quick lime
is called magnesium oxide or magnesia
Notice that the oxygen atom produced in the first step of this mechanism is consumed in the second step and therefore does not appear as a product in the overall reaction. Species that are produced in one step and consumed in a subsequent step are called intermediates.
I hope that helps
ps. not my words, my older cousins
Hey there!
Magnesium oxalate: MgC₂O₄
Mg: 1 x 24.305 = 24.305
C: 2 x 12.01 = 24.02
O: 4 x 16 = 64
----------------------------------
112.325 g/mol
The molar mass of magnesium oxalate is 112.325 g/mol.
Hope this helps!
