Select oxides from the range of substance formulas. Make up the reaction equations for their receipt. Name the oxides: SiH4, K2O, H3PO4, Ca (OH) 2, MnO2, CO2, FeS, NO2, Mg3N2
In this task, it is necessary to determine which of the following compounds are oxides: SiH4, K2O, H3PO4, Ca (OH) 2, MnO2, CO2, FeS, NO2.
Among these compounds, oxides are as follows.
K2O. It is called potassium oxide.
2K + K2O2 = 2K2O.
Combustion reaction.
MnO2. It is called manganese oxide.
Mn + O2 = MnO2.
Compound reaction or combustion reaction.
CO2. It is called carbon monoxide.
C + O2 = CO2.
Compound reaction or combustion reaction.
NO2. It is called nitric oxide.
2Pb (NO3) 2 = 2PbO + 4NO2 + O2.
Decomposition reaction.
