Write chemical formulas for compounds containing:
(a) one calcium atom for every two iodine atoms
(b) two nitrogen atoms for every four oxygen atoms
(c) one silicon atom for every two oxygen atoms
(d) one zinc atom for every two chlorine atoms
Solution 34P
Here, we are going to write the chemical formula for the following compounds.
Chemical formula is the representation of the number of atoms present in the molecule.
- one calcium atom for every two iodine atoms
Ca + 2 I --------> CaI2
Thus, one calcium atom and 2 iodine atoms form calcium iodide compound. The chemical formula of the molecular compound is CaI2.
(b) two nitrogen atoms for every four oxygen atoms
2N + 4 O --------> N2O4
Thus, two nitrogen atoms and 4 oxygen atoms form dinitrogen tetraoxide (N2O) compound. The chemical formula of the molecular compound is N2O4.
(c) one silicon atom for every two oxygen atoms
Si + 2 O --------> SiO2
Thus, one silicon atoms and 2 oxygen atoms form silicon dioxide (SiO2) compound. The chemical formula of the molecular compound is SiO2
(d) one zinc atom for every two chlorine atoms
Zn+ 2Cl --------> ZnCl2
Thus, one zinc atom and 2 chlorine atoms form zinc dichloride (ZnCl2) compound. The chemical formula of the molecular compound is ZnCl2.
