Answer:
Explanation:
First, the KClO3 moles is determined by using given grams of KCl produced from the reaction.
Next, the moles of O2 produced is obtained by using the moles of KClO3 which then, finally converted into mass of O2.
Analyzing the given chemical reaction clearly shows that, 2 moles of KClO3 produces 2 moles of KCl and 3 moles of O2.
From the given grams of KCl produced the initial grams of KClO3 used in the reaction is determined as follows,
The model correctly describes the locations of protons and electrons in the wave mechanical model of the atom is the <span>proton in nucleas, electron in regions of most probable location.

Answer:
32/21
Explanation:
Find the GCD (or HCF) of numerator and denominator. GCD of 32 and 21 is 1.
32 ÷ 121 ÷ 1.
Reduced fraction: 3221. Therefore, 32/21 simplified to lowest terms is 32/21.
