Determine what is wrong with the chemical formula and write the correct chemical formula for each of the following compounds: (a) (nh3)2c03 (ammonium carbonate), (b) caoh2 (calcium hydroxide), (c) cdso3 (cadmium sulfide), (d) zncro4 (zinc dichromate).

Answer and Explanation:

(A) this is the wrong formula of ammonium carbonates there should be  in place of and correct formula is  

(b)  is wrong formula of calcium hydroxide there should be in place of  and the correct formula is

(C)  is wrong formula of cadmium sulfide there should be only S in place of and the correct formula is CdS

(D) is wrong formula of zinc dichromate the correct formula is

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.
