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

A. H2O(L) - neutral
B. HC2H3O2(AQ) - acid pH<7
C. Ca(OH)2(AQ) - base pH>7
D. NH3(AQ)- base pH>7
Answer:
The larger the species, the further away from the nucleus the outer electrons are and hence the less strongly they are held. This means the bigger atoms will be more polarizable. So, the order from biggest-smallest molecules (strongest to weakest IMF) is iodine, bromine and finally chlorine.
