Answer 1

\(4P+5O_2\underrightarrow{t^o}2P_2O_5\)

\(Fe_2O_3+3H_2\underrightarrow{t^o}2Fe+3H_2O\)

\(CuO+H_2\underrightarrow{t^o}Cu+H_2O\)

\(2Mg+O_2\underrightarrow{t^o}2MgO\)

Answer 2

\(4P+5O_2\underrightarrow{^{^{t^0}}}2P_2O_5\)

\(Fe_2O_3+3H_2\underrightarrow{^{^{t^0}}}2Fe+3H_2O\)

\(CuO+H_2\underrightarrow{^{^{t^0}}}Cu+H_2O\)

\(2Mg+O_2\underrightarrow{^{^{t^0}}}2MgO\)
