How many grams of KCl are produced if 90 g KCIO3 decomposes? * 54.75 g KCI
13.69 g KCI
27.37 g KCI
37 g KCI

The chemical equation for the decomposition reaction of KClO₃ is the following one:

2KClO₃ → 2KCl + 3O₂

For determining the moles of KCl produced from 89,0 g of KClO₃ we are going to use the following conversion factor to go from grams of KClO₃ to moles of KCl:

So, 0,726 moles of KCl are produced.

The correct answer is b

A) the enthralling of formation for pure element in its standard state is always positivehope this : )
