For each of the following compounds, write the symbols of the ions in the compound, and the number of each ion in the molecule of that compound.

cal2
na2co3
ga(cio3)3
cuf2
(nh4)3po4
feso4
mg(no3)2
nh4no2
kc2h3o2
na2cr2o7

Using the subscripts from the given molecule we can find the symbols of cations, anions as well as number of ions.

Explanation:

CaI₂  =  Ca²⁺ and 2I⁻ ions

Na₂CO₃ = 2 Na⁺ and 1 CO₃²⁻

Ga(ClO₃)₃  = Ga³⁺ and ClO₃⁻

CuF₂  = Cu²⁺ and 2 F⁻

(NH₄)₃PO₄  = 3 NH₄⁺ and PO₄³⁻

FeSO₄   = Fe²⁺ and SO₄²⁻

Mg(NO₃)₂ = Mg²⁺ and NO₃⁻

NH₄NO₂ = NH₄⁺ and NO₂⁻

KC₂H₃O₂= K⁺ and CH₃COO⁻

Na₂Cr₂O₇ = 2Na⁺ and Cr₂O₇²⁻

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

they are all solids.
