Answer:
6moles of O2 will be produced
Explanation:
Step 1: write the correct and balance the equation
2KClO3 --------> 2KCl + 3O2
Step 2: find the mole
2 moles of KClO3 gives 3moles of O2
We are provided with 4 moles of KClO3,
Since 2 moles of KClO3 = 3 moles of O2
4 moles of KClO3 = x moles of O2
Cross multiply
2 = 3
4 = x
4 * 3 = 2 * x
12 = 2x
Divide both sides by 2 , to get the mole of O2
12/2 = 2x/ 2
6 = x
x = 6
The mole of O2 is 6 moles
Explanation:
Water waves are an example of waves that involve a combination of both longitudinal and transverse motions. As a wave travels through the waver, the particles travel in clockwise circles. The radius of the circles decreases as the depth into the water increases.
