Answer» a) C,H,,0 b) CHO c) CH-0. d) C,H,O, 4. Predict the sign of Ase for the REACTION. 2 H.S (8) +30. (9) ---2H,0 (g) + 2 So, (g) a) b) ove PIEDI cannot be predicted 5. Atoms or elements BELONGING to the same group of the periodic table will have a) Same number of protons b) Same number of electrons in Malance shell c) Same number of neutrons d) Same number Explanation: What will be molecular FORMULA of the compound? a) C,H,,0 b) CHO c) CH-0. d) C,H,O, 4. Predict the sign of Ase for the reaction. 2 H.S (8) +30. (9) ---2H,0 (g) + 2 So, (g) a) b) ove PIEDI cannot be predicted 5. Atoms or elements belonging to the same group of the periodic table will have a) Same number of protons b) Same number of electrons in Malance shell c) Same number of neutrons d) Same number of electrons |
