When 4.2 g NaHCO_(3) is added to a solution of CH_(3)COOH weighing 10.0 g, it is observed that 2.2 g CO_(2) is released into atmosphere . The residue is found is weigh 12.0 g . Show that these observations are in argreement with the law of conservation of mass. |

Answer» SOLUTION :`NaHCO_(3) + CH_(3)COOH to CH_(3)COONa + H_(2)O + CO_(2)` Initial mass =4.2 + 10=14.2 Final mass=12+2.2=14.2 Thus, during the COURSE of reaction law of conservation of mass is obeyed |
