a, \(PTHH:4P+5O_2\rightarrow2P_2O_5\)
\(n_P=\frac{46,5}{31}=1,5\left(mol\right)\)
\(\Rightarrow n_{O2}=1,875\left(mol\right)\)
\(\Rightarrow V_{O2}=1,875.22,4=42\left(l\right)\)
\(\Rightarrow V_{kk}=42.5=210\left(l\right)\)
b,\(PTHH:C+O_2\rightarrow CO_2\)
\(n_C=\frac{30}{12}=2,5\left(mol\right)\)
\(\Rightarrow n_{O2}=n_C=2,5\left(mol\right)\)
\(\Rightarrow V_{O2}=2,5.22,4=56\left(l\right)\)
\(\Rightarrow V_{kk}=56.5=280\left(l\right)\)
c,\(PTHH:4Al+3O_2\rightarrow2Al_2O_3\)
\(n_{Al}=\frac{67,5}{27}=2,5\left(mol\right)\)
\(\Rightarrow n_{O2}=1,875\left(mol\right)\)
\(\Rightarrow V_{O2}=1,875.22,4=42\left(l\right)\)
\(\Rightarrow V_{kk}=42.5=210\left(l\right)\)
d,\(PTHH:2H_2+O_2\rightarrow2H_2O\)
\(n_{H2}=\frac{33,6}{22,4}=1,5\left(mol\right)\)
\(\Rightarrow n_{O2}=0,75\left(mol\right)\)
\(\Rightarrow V_{O2}=0,75.22,4=16,8\left(l\right)\)
\(\Rightarrow V_{kk}=16,8.5=84\left(l\right)\)
