Taking into account the definition of net ionic equation, a precipitate of SrSO₄ is formed when When an aqueous solution of strontium chloride is added to an aqueous solution of potassium sulfate, and the net ionic equation is:

Sr⁺²(aq) + SO₄⁻²(aq) → SrSO₄(s)

The net ionic equation is a chemical equation for a reaction that lists only the species that participate in the reaction.

In other words, an ionic equation is a chemical equation where electrolytes in aqueous solution are written as dissociated ions. Usually this is a salt dissolved in water.

The balanced equation will be:

SrCl₂(aq) + K₂SO₄(aq) → 2KCl(aq) + SrSO₄(s)

where (aq) means aqueous and (s) solid.

Taking into account that:

All Cl⁻, Br⁻ and I⁻ salts are soluble. All alkali metal salts are soluble. (for example, Li, Na, K salts) Most sulfates are soluble, with the exception of Ba²⁺, Pb²⁺, Ag⁺ and Sr²⁺ sulfates.

The total ionic equation in separated aqueous solution will be:

Sr⁺²(aq) + 2 Cl⁻(aq) + 2 K⁺(aq) + SO₄⁻²(aq) → 2 K⁺(aq) + 2 Cl⁻(aq) + SrSO₄(s)

A spectator ion is an ion that appears both as a reactant and as a product in an ionic equation. Spectator ions can be either cations (positively charged ions) or anions (negatively charged ions).

When writing a net ionic equation, spectator ions found in the original equation are ignored. Thus, the total ionic reaction is different from the net chemical reaction.

In this case, K⁺ and Cl⁻ are the spectator ions because they appear unchanged in both the product and the reagent. So these ions cancel out by writing the net ionic equation and you get:

Sr⁺²(aq) + SO₄⁻²(aq) → SrSO₄(s)

Since SrSO₄ is an insoluble salt, it will precipitate.

Finally, a precipitate of SrSO₄ is formed when When an aqueous solution of strontium chloride is added to an aqueous solution of potassium sulfate, and the net ionic equation is:

Sr⁺²(aq) + SO₄⁻²(aq) → SrSO₄(s)

Answer from: reganwade8298

Sr²⁺ (aq)+ SO₄⁻²(aq) → SrSO₄(s)

Explanation:

The reactants of our reaction are:

SrCl₂ and K₂SO₄

The products of the reactios are:

SrSO₄ and KCl

We write the molecular reaction:

SrCl₂(aq) + K₂SO₄(aq) → 2KCl(aq) + SrSO₄(s) ↓

To state the net ionic equation we split the salts by their ions from the aqueous solutions. The solid product stays the same.

Sr²⁺ (aq) + 2Cl⁻(aq) + 2K⁺(aq) + SO₄⁻²(aq) → 2K⁺(aq) + 2Cl⁻(aq) + SrSO₄(s)

As the potassium cation and the chloride are repeated, they are spectators ions so they won't react in water. Finally our net ionic equation will be:

Sr²⁺ (aq)+ SO₄⁻²(aq) → SrSO₄(s)

Sulfates from elements of group 2, always produces precipitate

Answer from: Quest

If the water vapor content stays the same and the temperature drops, then the relative humidity increases. its vise versa.if the water vapor content stats the same and the temperature rises, the relative humidity decreases. so, yes, i'd say that temperature and humidity have a strong relationship.
