Chemistry - Will The Reaction Occur? | Summary and Q&A

TL;DR

The activity series helps determine if a single displacement reaction will proceed, based on the reactivity of the elements involved.

Key Insights

• 🔂 The reactivity of elements can be determined using the activity series, with more reactive elements displacing less reactive ones in single replacement reactions.
• 🗨️ Reactivity increases towards the left on the activity series, with lithium being the most reactive and silver and gold being the least reactive.
• ❓ Understanding the activity series helps predict if a reaction will proceed or if there will be no reaction.
• 👶 Single replacement reactions involve an element displacing another in a compound, resulting in the formation of new products.
• 🙃 Balancing the chemical equation for single displacement reactions involves adjusting the coefficients to ensure equal numbers of atoms on both sides.
• 🗨️ The activity series is particularly important when dealing with halogens in single replacement reactions, with reactivity increasing towards the left.
• 💁 Predicting the products of a single replacement reaction involves determining which element will displace another and forming the appropriate compounds.

Questions & Answers

Q: How can we determine if a single displacement reaction will proceed?

We can use the activity series and compare the reactivity of the elements involved. If the displacing element is more reactive, the reaction will proceed.

Q: What are the products of a single replacement reaction between zinc and copper II chloride?

The zinc will displace the copper in the compound, resulting in solid copper precipitating out and zinc pairing up with chlorine to form zinc chloride.

Q: What is the role of the activity series in predicting reaction outcomes?

The activity series helps determine the relative reactivity of elements, allowing us to predict if a displacement reaction will occur or if it will be a no reaction.

Q: How do we balance the chemical equation for a single replacement reaction?

We adjust the coefficients in front of the compounds to ensure that the number of atoms on both sides of the equation is balanced.

Summary & Key Takeaways

• Single displacement reactions involve one element displacing another in a compound.

• The activity series lists elements in order of reactivity, with lithium being the most reactive and silver and gold being the least reactive.

• By comparing the reactivity of elements, we can determine if a reaction will proceed and predict the products.
