PT: \(Zn+2HCl\rightarrow ZnCl_2+H_2\)
___0,3____0,6_____0,3____0,3 (mol)
a, \(m_{Zn}=0,3.65=19,5\left(g\right)\)
b, \(m_{HCl}=0,6.36,5=21,9\left(g\right)\)
c, \(m_{ZnCl_2}=0,3.136=40,8\left(g\right)\)
Bạn tham khảo nhé!
Zn+2HCl->ZnCl2+H2
0,3---0,6-----0,3----0,3 mol
=>m Zn=0,3.65=19,5g
=>m HCl=0,6.35,6=21,9g
=>m ZnCl2=0,3.136=40,8g
