Carbon monoxide (CO) reacts with hydrogen (H2) to form methane (CH4) and water (H2O). Upper C upper O (g) plus 3 upper H subscript 2 (g) double-headed arrow upper C upper H 4 (g) plus upper H subscript 2 upper O (g). The reaction is at equilibrium at 1,000 K. The equilibrium constant of the reaction is 3. 90. At equilibrium, the concentrations are as follows. [CO] = 0. 30 M [H2] = 0. 10 M [H2O] = 0. 020 M What is the equilibrium concentration of CH4 expressed in scientific notation? 1959 5. 9 x 10-2 0. 059 5. 9 x 102.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
