300/ 15 = 20
divide bar graph into 20 equal sections
each section represents one week
algebra
number of weeks = x
15x = 300
x = 300/15
x = 20

3+0=3
3-0=3
I don't know that one sorry :(
5 + 11= 11 + 5
-3 + 0 = -3
-3 - 0 = -3
IDK? sorry
7 - 1 = -1 - -7
hope I helped tho :)
Answer: 3 mol of O₂
Solution:
The Balance chemical equation is as follow,
2 KClO₃ → 2 KCl + 3 O₂
According to this equation on decomposition 2 moles of Potassium chlorate (KClO₃) produces 2 moles of Poatassium chloride (KCl) and 3 moles of oxygen gas (O₂).
Therefore, when,
2 moles of KClO₃ produces = 3 moles of O₂
So,
2 moles of KClO₃ will produce = X moles of O₂
Solving for X,
X = (2 mol × 3 mol) ÷ 2 mol
X = 3 mol of O₂
Using above method you can calculate any amount of O₂ or KCl produced by decomposing any amount of KClO₃.
