a) C + O2 --to--> CO2
b) \(n_C=\dfrac{24}{12}=2\left(mol\right)\)
=> nCO2 =2 (mol)
=> mCO2 = 2.44 = 88(g)
c)
nO2 = 2(mol)
=> VO2 = 2.22,4 = 44,8 (l)
=> Vkk = 44,8.5=224(l)
a)
$C + O_2 \xrightarrow{t^o} CO_2$
b)
$n_{CO_2} = n_C = \dfrac{24}{12} = 2(mol)$
$m_{CO_2} = 2.44 = 88(gam)$
c)
$n_{O_2} = n_C = 2(mol)$
$V_{O_2} = 2.22,4 = 44,8(lít)$
$V_{không\ khí} =5 V_{O_2} = 44,8.5 = 224(lít)$
a: \(C+O_2\rightarrow CO_2\)
b: \(n_C=\dfrac{24}{12}=2\left(mol\right)\)
\(\Leftrightarrow n_{CO_2}=2\left(mol\right)\)
\(\Leftrightarrow m_{CO_2}=2\cdot44=88\left(g\right)\)
\(n_C=\dfrac{24}{12}=2\left(mol\right)\\a, C+O_2\rightarrow\left(t^o\right)CO_2\\b,n_{O_2}=n_{CO_2}=n_C=2\left(mol\right)\\ m_{CO_2}=2.44=88\left(g\right)\\ c,V_{O_2\left(\text{đ}ktc\right)}=2.22,4=44,8\left(l\right)\\ V_{kk\left(\text{đ}ktc\right)}=5.V_{O_2\left(\text{đ}ktc\right)}=5.44,8=224\left(l\right)\)
