Question

Write complete, balanced equations for the following reactants. Be sure to state whether the reaction is single or double displacement if it is single displacement State whether cations are displaced or the anions are displaced

Answer 1

The question involves writing and balancing a chemical equation for a double displacement reaction where ethanoic acid and calcium hydroxide react to form calcium ethanoate and water.

Step-by-step explanation:

The subject of this question is focused on double displacement reactions in chemistry. A double displacement reaction is a type of chemical reaction where the cations and anions of two different compounds exchange places, forming two new compounds. This type of reaction often results in the formation of a precipitate, a gas, or a less soluble substance. Let's balance the given unbalanced equation:

`CH_3CH_2CO_2H(aq) + Ca(OH)_2(aq) → (CH_3CH_2CO_2)2Ca(aq) + 2 H_2O(l)`

The reaction between ethanoic acid
`(CH_3CH_2CO_2H)` and calcium hydroxide
`(Ca(OH)_2)` is a double displacement reaction, where the exchange of ions leads to the creation of water
`(H_2O)` and a salt (calcium ethanoate -
`(CH_3CH_2CO_2)_2Ca).` Here, each molecule of ethanoic acid displaces a hydroxyl ion (OH-) from calcium hydroxide, thereby forming two molecules of water in the process.
