What does a complete ionic equation look like? A. All ionic substances are written as separate ions in solution. B. All ionic substances are written with the state symbol (aq) after it. C. All substances are written as ionic compounds bonded together. D. All substances are labeled with the oxidation states of the atoms.

B

Explanation:

Similar to a molecular equation, which expresses compounds as molecules, an ionic equation is a chemical equation in which the electrolytes in aqueous solution are expressed as dissociated ions. Usually, this is a salt dissolved in water, where the ionic species are followed by (aq) in the equation to indicate they are in aqueous solution.

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.

it's all four options.
