When potassium reacts with oxygen, it forms potassium oxide (K2O). In potassium oxide, the ratio of potassium ions (K⁺) to oxide ions (O²⁻) is 2:1. This is because each potassium ion has a +1 charge, while each oxide ion has a -2 charge, so there must be two potassium ions for every one oxide ion to balance the charges.
The chemical equation for the reaction between potassium and oxygen is: 4K + O2 -> 2K2O
The chemical equation for the reaction between potassium and oxygen is: 4K + O2 -> 2K2O.
The reaction between potassium chlorate and oxygen gas generates potassium chloride and oxygen gas. Therefore, the amount of potassium chlorate produced from the reaction is equal to the amount of potassium chlorate that was used, which is 500 grams.
When potassium bromate is heated, it decomposes into potassium bromide and oxygen gas. This reaction is a decomposition reaction, where a single compound breaks down into two or more simpler substances.
The reaction shown is a decomposition reaction where potassium chlorate (KClO3) breaks down into potassium chloride (KCl) and oxygen gas (O2). This type of reaction occurs when a compound breaks down into simpler substances.
