Hydrogen cyanide is produced industrially from the reaction of gaseous ammonia, oxygen and mthane. `2NH_(3) (g) + 3O_(2) (g) + 2CH_(4) (g) rarr 2HCN (g) + 6H_(2) O (g)` If `5 kg` of each reactant is used then what mass of `H_(2)O (g)` will be formed.A. `5.6 gm`B. `2.81 kg`C. `5.29 kg`D. `8.43 kg` |

Answer» Correct Answer - C `{:(,2NH_(3) (g),+,3 O_(2) (g),+,2 CH_(4) (g),rarr,2 HCN (g),+,6 H_(2)O (g),),(,5 kg,,5 kg,,5 kg,,,,,),(n =,(5)/(17) K "mole",,(5)/(32) K "mole",,(5)/(16) K "mole",,,,,),(,O_(2) "is" LR,,,,,,,,,):}` Moles of `H_(2)O` formed `= (5)/(32) xx 2 xx 10^(3)` mole `= (5)/(16) K` mole Mass of water formed `= (5)/(16) xx 18 xx 10^(3) gm` `= 5.6 Kg` |
