Answer:
The elements in the reactants are the same as the elements in the products.
Explanation:
You can't have more or less elements or atoms, but you also can't just have the same number of atoms because then it could be different elements, which can't happen.
Double replacement, C6H12 and 9O2 yield two different compounds so its a double replacement equation.
Butane is
from the family of alkanes with –ane as its family name. The but- prefix stands
for having four carbon atoms. The C4H10 is the general formula of butane and
can also represent other forms or structures of butane. However if the question
asks for the molecular formula of butane, think of how many electrons it can
share to the hydrogen atom. The carbon atom can share 4 and hydrogen 1. So if the three hydrogen atoms are attached
to the first carbon, the other shared electron is attached to the second
carbon. The second carbon atom can accommodate two hydrogen and 1 carbon. The
third carbon can accommodate 2 hydrogen atoms and 1 carbon and the fourth
carbon can accommodate 3 hydrogen atoms. The molecular formula is
CH3-CH2-CH2-CH3.
The moles of oxygen produced is calculated as follows
write a balanced reacting equation, that is
Mg(ClO3)2 ---->MgCl2 + 3O2
from the equation above the reacting ratio of Mg(ClO3)2 to O2 is 1: 3 therefore the moles of O2 produced = 5.12 moles x3 =15.36 moles
