Làm giúp mình nha! Ai đúng mình tick cho
\(n_{H_2SO_4}=1,8\left(mol\right);n_{Ni}=0,16875\left(mol\right)\)
Đặt \(n_{F\text{e}}=x;n_{Cu}=y;n_{c\text{r}}=z\left(mol\right)\)
TN1: Cho Y td H2SO4
Fe3O4 + 8H+ -----> 2Fe3+ + Fe2+ + 4H2O
\(\frac{1}{3}x\)\(_{\rightarrow}\)______\(\frac{8}{3}x\)______\(\frac{2}{3}x\)_____\(\frac{1}{3}x\)
CuO + 2H+ -----> Cu2+ + H2O
y\(_{\rightarrow}\)______2y_______y
Cr2O3 + 6H+ -----> 2Cr3+ + 3H2O
0,5z\(_{\rightarrow}\)____3z________z
\(\Rightarrow n_{H^+}=\frac{8}{3}x+2y+3\text{z}=3,6\left(1\right)\)
TN2: Cho \(\frac{1}{4}\)Z td Ni
Ni + 2Fe3+ -----> Ni2+ + 2Fe2+
\(\frac{1}{12}x\)__\(_{\leftarrow}\frac{1}{6}x\)
Ni + Cu2+ -----> Ni2+ + Cu
\(\frac{y}{4}\)____\(_{\leftarrow}\frac{1}{4}y\)
\(\Rightarrow\frac{1}{12}x+\frac{1}{4}y=0,16875\)
\(\Rightarrow m_{KL}=56\text{x}+64y+52\text{z}=\frac{52}{3}\left(\frac{8}{3}x+2y+3\text{z}\right)+\frac{352}{3}\left(\frac{x}{12}+\frac{y}{4}\right)=82,2\left(g\right)\)
TN3: Cô cạn 3 phần còn lại
mchất rắn \(=\frac{3}{4}\left(m_{KL\left(Z\right)}+m_{SO_4^{2^-}\left(Z\right)}\right)=\frac{3}{4}\left(82,2+96\cdot1,8\right)=191,25\left(g\right)\)
True đấy nhưng về cách trình bày đừng doạ tao bằng ion mày ơi :)) Thu gọn ion thì thu gọn cho trót là O2-+H+ đi còn CuO+H+ :3
