The following reactions ar an example of what kind of reaction?ZnBr2(aq) + 2AgNO3(aq) -> Zn(NO3)2(aq) + 2AgBr(s)
a) precipitation reaction
b) acid=base reaction
c) oxidation-reduction reaction
Answers
Answer: A) precipitation reaction
Explanation: In the products of the reaction, AgBr is a solid. Since the starting reagents were both aqueous, this is indicative of a precipitation reaction.
Choice B is wrong because both the starting materials and the final products are inorganic salts, not acids and bases. Choice C is wrong because the oxidation numbers for Zn, Br, Ag, and the NO3 anion didn't change in the reaction.
Final answer:
The given reaction, ZnBr2(aq) + 2AgNO3(aq) -> Zn(NO3)2(aq) + 2AgBr(s), is an example of a precipitation reaction.
Explanation:
The given reaction, ZnBr2(aq) + 2AgNO3(aq) -> Zn(NO3)2(aq) + 2AgBr(s), involves the combination of aqueous solutions of ZnBr2 and AgNO3. The products formed are Zn(NO3)2, which remains in the aqueous state, and AgBr, which precipitates as a solid.
This reaction is an example of a precipitation reaction. In a precipitation reaction, two aqueous solutions react to form an insoluble solid called a precipitate. In this case, the silver ions (Ag+) from AgNO3 react with the bromide ions (Br-) from ZnBr2 to form AgBr, which is insoluble in water and appears as a solid.

The element which has an electron configuration of [Kr] 5s² is calcium .
It is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with sameatomic numberare atoms of same element.

Word Equation: Calcium chloride + Silver nitrate → Calcium nitrate + Silver chloride (precipitate).
Type of Reaction: Double displacement (precipitation).
The chemical equation can be converted into a word equation as follows:
Word Equation:
Calcium chloride (aqueous) + Silver nitrate (aqueous) → Calcium nitrate (aqueous) + Silver chloride (solid)
Type of Reaction:
This is a double displacement reaction, specifically a precipitation reaction. In a double displacement reaction, the cations and anions of two compounds switch places, resulting in the formation of two new compounds. In this particular case, when calcium chloride and silver nitrate are mixed, calcium nitrate and silver chloride are formed.
Furthermore, it's a precipitation reaction because one of the products, silver chloride, is insoluble in water and forms a solid (precipitate) rather than remaining in solution. The solid silver chloride is observed as a white, cloudy precipitate that settles at the bottom of the reaction vessel.

Final answer:
Water is considered a universal solvent due to its polar nature, which enables it to dissolve ionic compounds and polar molecules. This is because water's charged particles form hydrogen bonds with surrounding water molecules, creating hydration shells that keep the solute particles dispersed. This unique property allows water to dissolve a variety of substances.
Explanation:
Water is considered a universalsolvent because of its polar nature. Being polar, water has slight positive and negative charges, making it capable of dissolving ionic compounds and polar molecules. These charged particles form hydrogen bonds with water molecules, forming hydration shells that keep the solute particles separated or dispersed in the water. This ability of water to dissolve a wide range of substances makes it a universal solvent.
