Which of the statements below correctly describe(s) ammonium chloride? (1) It consists mainly of simple molecules. (2) Ionic bond is present in it. (3) It has covalent bonds A. (1) and (2) B. (2) and (3) C. (1) and (3) D. (1), (2) and (3) p.s. pls explain,,don;t just give me the answer... thank you very much 更新: the correct ans for the two question should be D and B respectively
最佳解答:
(1) Statement 1: Correct. Ammonia gas can dissolve in water to give basic aqueous solution. Statement 2: Correct. Since ammonia is basic, all acid can react with it to form ammonium salt. Statement 3: Incorrect. Since carbon tetrachloride is non-polar in nature but ammonia is polar. Ans: A (2) Statement 1: Correct. NH4+ can be regarded as a molecular ion. Statement 2: Correct. Those ionic bonds are between NH4+ and Cl-. Statement 3: Correct. Those covalent bonds are between N and H within NH4+. Ans: D
