Question

for each of the following, write an unbalanced chemical reaction equation (including states of matter) that accurately represents the process described:

1. when beryllium chloride is dissolved in aqueous silver nitrate, aqueous beryllium nitrate and solid silver chloride are formed.
2. when isopropanol (c₃h₈o) burns in oxygen; carbon dioxide, water, and heat are produced.
3. when aqueous sodium hydroxide reacts with sulfuric acid (h₂so₄), aqueous sodium sulfate, water, and heat are formed.
4. when fluorine gas is put into contact with calcium metal at high temperatures, calcium fluoride powder is created in an exothermic reaction.

Explanation:

Step1: Identify reactants and products for each reaction

For reaction 1: Reactants are beryllium chloride (\(BeCl_{2}(aq)\)) and silver nitrate (\(AgNO_{3}(aq)\)), products are beryllium nitrate (\(Be(NO_{3})_{2}(aq)\)) and silver chloride (\(AgCl(s)\)).
For reaction 2: Reactant is isopropanol (\(C_{3}H_{8}O(l)\)) and oxygen (\(O_{2}(g)\)), products are carbon dioxide (\(CO_{2}(g)\)) and water (\(H_{2}O(g)\)).
For reaction 3: Reactants are sodium hydroxide (\(NaOH(aq)\)) and sulfuric acid (\(H_{2}SO_{4}(aq)\)), products are sodium sulfate (\(Na_{2}SO_{4}(aq)\)) and water (\(H_{2}O(l)\)).
For reaction 4: Reactants are fluorine gas (\(F_{2}(g)\)) and calcium metal (\(Ca(s)\)), product is calcium fluoride (\(CaF_{2}(s)\)).

Step2: Write unbalanced chemical equations

For reaction 1: \(BeCl_{2}(aq)+AgNO_{3}(aq)
ightarrow Be(NO_{3})_{2}(aq)+AgCl(s)\)
For reaction 2: \(C_{3}H_{8}O(l)+O_{2}(g)
ightarrow CO_{2}(g)+H_{2}O(g)\)
For reaction 3: \(NaOH(aq)+H_{2}SO_{4}(aq)
ightarrow Na_{2}SO_{4}(aq)+H_{2}O(l)\)
For reaction 4: \(F_{2}(g)+Ca(s)
ightarrow CaF_{2}(s)\)

Answer:

1. \(BeCl_{2}(aq)+AgNO_{3}(aq)

ightarrow Be(NO_{3})_{2}(aq)+AgCl(s)\)

1. \(C_{3}H_{8}O(l)+O_{2}(g)

ightarrow CO_{2}(g)+H_{2}O(g)\)

1. \(NaOH(aq)+H_{2}SO_{4}(aq)

ightarrow Na_{2}SO_{4}(aq)+H_{2}O(l)\)

1. \(F_{2}(g)+Ca(s)

ightarrow CaF_{2}(s)\)
