A double displacement reaction is a type of chemical reaction where two compounds exchange their ions to form two new compounds. In these reactions, the general pattern can be represented as:

• AB + CD 鈫� AD + CB

This means that parts of two ionic compounds swap with each other, resulting in the formation of two new substances.
In the given exercise, sodium hydroxide (NaOH) and magnesium nitrate (Mg(NO\(_3\))\(_2\)) are mixed. The sodium ions (Na\(^+\)) and nitrate ions (NO\(_3\)\(^-\)) swap places with the hydroxide ions (OH\(^-\)) and magnesium ions (Mg\(^{2+}\)) as they react."},{"concept_headline":"Solubility Rules","text":"Solubility rules are a set of guidelines used to predict whether an ionic compound is soluble or insoluble in water. These rules can help to predict the states of the products in a chemical reaction.
Here are some general solubility rules:

• Most nitrate (NO\(_3\)\(^-\)) salts are soluble in water.
• Most hydroxide (OH\(^-\)) salts are only slightly soluble, with exceptions such as sodium and potassium hydroxide.

In the exercise, sodium nitrate (NaNO\(_3\)) is formed, which is soluble and remains in aqueous form (aq). Magnesium hydroxide (Mg(OH)\(_2\)) is only slightly soluble, leading it to form a precipitate, or solid (s). This understanding helps to determine the states of products in the balanced chemical equation."},{"concept_headline":"Balanced Chemical Equation","text":"A balanced chemical equation accurately represents what happens in a chemical reaction. It ensures that the number of atoms for each element is equal on both the reactant and product sides of the equation. This maintains the law of conservation of mass.
For the exercise at hand, the balanced equation is:\[2 \text{NaOH} \, (aq) + \text{Mg(NO}_3)_2 \, (aq) \rightarrow 2 \text{NaNO}_3 \, (aq) + \text{Mg(OH)}_2 \, (s)\]
Balancing involves making sure that for every sodium (Na), oxygen (O), hydrogen (H), magnesium (Mg), and nitrogen (N) atom on the reactant side, there's a corresponding atom count on the product side. This equation also shows the state of each compound, indicating sodium nitrate is dissolved in water while magnesium hydroxide forms a solid precipitate."}]} 褟斜褉(),'Magnesium hydroxide precipitates as a solid when formed, as indicated by the (s) next to it in the balanced chemical equation, making option (c) of the original question the correct answer. Balancing equations and understanding how ions exchange places during double displacement reactions, along with using solubility rules, are key skills in predicting and verifying this post-reaction scenario.]}]} 頃勳劯鞖�.) 17 the reaction precisely accurately understand how these work.utc-ing to master reactions and accurately predict product form when chemicals are mixed together袙邪卸薪芯 ? 褔褌芯 keep mind to review```# Possible balanced experiment, forming an solid that work 韮愳姽旒�"The_balance 褌械斜褨薪").
