KMnO4 + 8HCl ---------> MnCl2 + 2Cl2 + 4H2O + KCl you need 8 HCl to give 4 water molecules from the 4 oxygens on permanganate. However that only gives 7 chlorines on the RHS to 8 on the LHS. So double everything up and add one chlorine
2KMnO4 + 16HCl ---------> 2MnCl2 +5Cl2 + 8H2O + 2KCl which is balanced
2HNO3 (Aq) + K2CO3 (s) = CO2 (Aq) +H20 (l) +2KNO3 (Aq)
HNO3 is a strong acid, certain salts, notably carbonates CO3, Sulfites, SO3, and sulfides S react with acids to form gaseous products such as CO2, and water. This process is call Neutralization Reaction With Gas Formation.
It doesn't. 2K2O + 4MnO + 5O2 yields 4KMnO4 . The equation has to be balanced
4KMnO4 yields 2K2O + 4MnO + 5O2
4 KMnO4 = 2 K2MnO + 2 MnO2 + 5 O2
Balanced equation 2KNO3 --> 2KNO2 + O2

The answer is: 4 KMnO4=2 K2O+4 MnO+5 O2
The balanced equation is 2HCl + K2O -> H2O + 2KCl.
An equation refers to a reaction, not an individual compound. The formula of potassium oxide is K2O. If you mean the equation for its formation from the elements, it is 4K + O2 --> 2K2O.
A possible reaction is:Fe2O3 + 6 K = 3 K2O + 2 Fe
2KOH + H2SO3 --------> K2SO3 + 2H2O or K2O + SO2 ------> K2SO3
The answer is: 4 KMnO4=2 K2O+4 MnO+5 O2
The balanced equation is 2HCl + K2O -> H2O + 2KCl.
An equation refers to a reaction, not an individual compound. The formula of potassium oxide is K2O. If you mean the equation for its formation from the elements, it is 4K + O2 --> 2K2O.
3H2C2O4 + 2K2MnO4 = 6CO2 + 2K2O + Mn2O3 + 3H2O
A possible reaction is:Fe2O3 + 6 K = 3 K2O + 2 Fe
2K + H2O ----> K2O + H2
2KOH + H2SO3 --------> K2SO3 + 2H2O or K2O + SO2 ------> K2SO3
k2o+ h2co3 --> h2o + k2co3
The combination of potassium (K) and oxygen (O2) produces K2O (potassium oxide). The balanced equation is 2K + O2 ==> K2O. The answer provided previously is incorrect. The compound KO does not exist.

ZnO+ KOH→K2O+Zn(OH)2
K2O is potassium oxide
