2023年1月4日 · Here, MnO2 is reduced to MnCl2, losing oxygen and gaining chlorine. Let's review the given options now. The first statement says that HCL is oxidised to Cl2. Looking at the oxidation half we can easily figure out that the statement is true. The second statement says that MnO2 is reduced to MnCl2. Which is true too, as we look at the reduction half.

2019年2月11日 · MnO4^- + I - ----> MnO2 + I2 . first let us find oxidation no. of I . oxidation state of oxygen is alway -2 except in peroxides n other cases . charge on I is -1 so its oxidation no. is -1. hope you completely understood the concept

2020年8月7日 · In the reaction MnO2 + 4HCl -> MnCl2 + Cl2 + 2H2O , Cl (chlorine) is the substance which is oxidized from the HCl, and it is the reducing agent for the MnO2 as well. As Cl is the oxidized substance in HCl, thus it is the oxidizing agent in the reaction.

2023年2月14日 · A: 2 KMnO4 - K2MnO4 + MnO2 + O2. Explanation: In a disproportionation reaction, a single substance is simultaneously oxidized and reduced to form two different products. In option A, potassium permanganate (KMnO4) is disproportionated to form potassium manganate (K2MnO4) and manganese dioxide (MnO2) as the products.

2023年7月13日 · The balanced equation for the reaction between HCl and MnO2 is: `4HCl + MnO2 -> MnCl2 + 2H2O + Cl2`. From this equation, we can see that 4 moles of HCl react with 1 mole of MnO2. The molar mass of MnO2 is 86.94 g/mol. So, 69.6 g of MnO2 is equivalent to (69.6 g) / (86.94 g/mol) = 0.8 moles of MnO2.
