\(n_{Mg}=\frac{3,6}{24}=0,15\left(mol\right)\)
\(PTHH:2Mg+O_2\underrightarrow{^{to}}2MgO\)
a)
Theo PTHH:
\(n_{MgO}=n_{Mg}=0,15\left(mol\right)\)
\(\Rightarrow m_{MgO}=0,15.40=6\left(g\right)\)
b)
Theo PTHH:
\(n_{O2}=\frac{n_{Mg}}{2}=\frac{0,15}{2}=0,075\left(mol\right)\)
\(\Rightarrow V_{O2}=0,075.22,4=1,68\left(l\right)\)
c)\(\Rightarrow V_{kk}=V_{O2}.5=1,68.5=8,4\left(l\right)\)
