Answer in detail II
Exercise condition:
5
m.
Write out the various chemical properties of carbon.
a.
Carbon with oxygen reaction is
\(2C_(s)\) + \(O_2{_(g)}\) → \(2CO_(g)\) + heat
\(W\) + \(C\) → \(WC\)
\(C_(s)\) + \(H_2O_(g)\) → \(CO_(g)\) + \(H_2{_(g)}\)
\(CH_4{_(g)}\) + \(2O_2{_(g)}\) → \(CO_2{_(g)}\) + \(2H_2O_(g)\)
\(C_(s)\) + \(2S_(g)\) → \(CS_2{_(g)}\)
.
b.
Combustion reaction is
\(2C_(s)\) + \(O_2{_(g)}\) → \(2CO_(g)\) + heat
\(C_(s)\) + \(H_2O_(g)\) → \(CO_(g)\) + \(H_2{_(g)}\)
\(CH_4{_(g)}\) + \(2O_2{_(g)}\) → \(CO_2{_(g)}\) + \(2H_2O_(g)\) + heat
\(W\) + \(C\) → \(WC\)
\(C_(s)\) + \(2S_(g)\) → \(CS_2{_(g)}\)
.
c.
Carbon with steam reaction is
\(W\) + \(C\) → \(WC\)
\(C_(s)\) + \(H_2O_(g)\) → \(CO_(g)\) + \(H_2{_(g)}\)
\(CH_4{_(g)}\) + \(2O_2{_(g)}\) → \(CO_2{_(g)}\) + \(2H_2O_(g)\) + heat
\(2C_(s)\) + \(O_2{_(g)}\) → \(2CO_(g)\) + heat
\(C_(s)\) + \(2S_(g)\) → \(CS_2{_(g)}\)
.
d.
Carbon with Sulphur reaction is
\(C_(s)\) + \(H_2O_(g)\) → \(CO_(g)\) + \(H_2{_(g)}\)
\(C_(s)\) + \(2S_(g)\) → \(CS_2{_(g)}\)
\(2C_(s)\) + \(O_2{_(g)}\) → \(2CO_(g)\) + heat
\(W\) + \(C\) → \(WC\)
\(CH_4{_(g)}\) + \(2O_2{_(g)}\) → \(CO_2{_(g)}\) + \(2H_2O_(g)\) + heat
.
e.
Carbon with metal reaction is
\(C_(s)\) + \(H_2O_(g)\) → \(CO_(g)\) + \(H_2{_(g)}\)
\(CH_4{_(g)}\) + \(2O_2{_(g)}\) → \(CO_2{_(g)}\) + \(2H_2O_(g)\) + heat
\(W\) + \(C\) → \(WC\)
\(C_(s)\) + \(2S_(g)\) → \(CS_2{_(g)}\)
\(2C_(s)\) + \(O_2{_(g)}\) → \(2CO_(g)\) + heat
