a. nMg = \(\dfrac{9,6}{24}\) = 0,4 (mol)
Mg + 2CH3COOH ---> 2(CH3COO)2Mg +H2
(mol) 0,4 0,8 0,4
=> V H2 = 0,4.22,4=8,96 (l)
c. Vdd CH3COOH = \(\dfrac {0,8} {0,5}\) = 1,6 (l)
a) Mg + 2CH3COOH ------ (CH3COO)2Mg + H2
a. Mg+2CH3COOH->(CH3COO)2Mg+H2
Ta có:\(n_{Mg}=\dfrac{9,6}{24}=0,4\left(mol\right)\)
Mg +2CH3COOH->(CH3COO)2Mg+H2
0,4mol 0,8mol 0,4mol
=>VH2=0,4.22,4=8,96(l)
c.Ta có:Vdd=\(\dfrac{0,8}{0,5}=1,6\left(l\right)\)
đúng thì tick nhé
