Question

The reaction which proceed in the forward direction is

• A. $Fe_2O_3 + 6HCI \rightarrow \, 2FeCI_3+3H_2O$
• B. $NH_3+H_2O+NaCI \rightarrow \, NH_4CI + NaOH$
• C. $SnCI_4 +HgCI_2 \rightarrow 2SnCI_2+2HgCl_2$
• D. $2CuI+I_2+4H^+ \rightarrow 2Cu^{2+}+4KI$

Answer 1

Answer: (A)

$Fe_2O_3 + 6HCI \rightarrow \, 2FeCI_3+3H_2O$

Answer 2

Fe$_2O_3$ is a basic oxide, neutralised by HCI spontaneously forming FeCI$_3$ and water.
