Відповідь:

2H2(гідроген) + O2 (кисень) = 2H2O (гідроген оксид)

2K(калій) + O2(кисень) = 2K2O (калій оксид)

2Zn(цинк) + O2(кисень )= 2ZnO (цинк оксид)

4B(Бор) + 3O2(кисень) = 2B203 (бор оксид)

Si(силіцій)+ O2(кисень) = SiO2 (силіцій оксид)

4As(арсен) + 5O2(кисень) = 2As2O5 (арсен оксид)

Se(селен) + O2(кисень) = SeO2 (селен оксид)

2I2(йод) + 5O2(кисень) = 2I205 (йод оксид)

2Ar(аргентум) + O2(кисень) = 2Ar2O (аргентум оксид)
