\(n_{Cl_2}=a\left(mol\right)\)
\(n_{O_2}=b\left(mol\right)\)
\(n_Y=a+b=\dfrac{5.6}{22.4}=0.25\left(mol\right)\left(1\right)\)
\(m_Y=71a+32b=12.8\left(g\right)\left(2\right)\)
\(\left(1\right),\left(2\right):a=\dfrac{8}{65},b=\dfrac{33}{260}\)
\(1,\\ a,m_{hh}=3.44+2.28=188(g)\\ b,m_{hh}=\dfrac{2,24}{22,4}.64+\dfrac{1,12}{22,4}.32=8(g)\\ 2,\\ a,V_{hh}=(\dfrac{4,4}{44}+\dfrac{0,4}{2}).22,4=6,72(l)\\ b,V_{hh}=(\dfrac{6.10^{23}}{6.10^{23}}+\dfrac{3.10^{23}}{6.10^{23}}).22,4=33,6(l)\)
a) nFe= \(\frac{m_{Fe}}{M_{Fe}}=\frac{5,6}{56}=0,1\left(mol\right)\)
nCu=\(\frac{m_{Cu}}{M_{Cu}}=\frac{64}{64}=1\left(mol\right)\)
nAl= \(\frac{m_{Al}}{M_{Al}}=\frac{27}{27}=1\left(mol\right)\)
b) \(n_{CO_2}=\frac{m_{CO_2}}{M_{CO_2}}=\frac{44}{44}=1\left(mol\right)\)
\(n_{H_2}=\frac{m_{H_2}}{M_{H_2}}=\frac{4}{2}=2\left(mol\right)\)
a) nFe = 5,6/56 = 0,1 mol
nCu = 64/64 = 1 mol
nAl = 27/27 = 1 mol
b) nCO2 = 44/44 = 1 mol
=> VCO2 = 1.22,4 = 22,4 l
nH2 = 4/2 = 2 mol
=> VH2 = 2.22,4 = 44,8 l
a) nFe= \(\frac{5,6}{56}\)= 0,1 mol
nCu= \(\frac{64}{64}\)= 1mol
nAl= \(\frac{27}{27}\)= 1 mol
b)
nCO2= \(\frac{44}{12+16.2}\)= 1 mol
nH2= \(\frac{4}{1.2}\)= 2 mol
=> nhh= 1+2= 3 mol
Vhh= 3.22,4= 67,2 l
a) Số mol Fe trong 5,6 g Fe:
nFe=\(\frac{m_{Fe}}{M_{Fe}}=\frac{5,6}{56}=0,1\left(mol\right)\)
Số mol Cu có trong 64 g Cu:
nCu=\(\frac{m_{Cu}}{M_{Cu}}=\frac{64}{64}=1\left(mol\right)\)
Số mol Al có trong 27 g Al:
nAl= \(\frac{m_{Al}}{M_{Al}}=\frac{27}{27}=1\left(mol\right)\)
