Answer 1

First and last reactions are not possible according to the Dalton's theory whereas second one is possible.

Dalton's atomic theory states that 1) All matter is made of atoms that are not divisible as well as destructibles 2) All atoms of a given element are identical in mass, size and many other chemical or physical properties. 3). A chemical reaction is a rearrangement of the atoms taking part in it. It means that atoms are neither created non destroyed during chemical reaction. .4) The atoms of different elements combine in. fixed ratio.s to form products. It means that the total no. of atoms remains same before and after the chemical reaction... (i) e ela Chai & It is not possible according to Dalton's atomic theory, because • before and after the reaction, no, of el-atomid . H-atoms are not same. Again, el-atoms get destroyed and H-atoms are created. celij N2 + 3H2 + 2NH3 It is possible according to Dalton's theory. all points /Written above) are being obeyed in : this reaction. - 1 2H₂ + O2 . 2H₂O + Au. It is not possible according to Dalton's theory. because - • Au-atom is created in this reaction. (against Dalton's theory) though no, of H-atoms & - atoms are same before and after the reaction.
