The answer is Strontium Nitride
80.5%- The total mass of the compound is 18g (14.5 + 3.5) then divide the mass of magnesium by the total. easy way to remember is- (part/whole) x 100
1. opposite
2. positive
3. negative
Explanation:
(a)
Cancelling common terms, the overall reaction is as follows:
(b)
Chemical species which are generated and consumed during the reaction are called intermediates. Therefore, in the given reaction, HClO(aq), OH-(aq) and HIO(aq) are intermediate species.
(c)
two reactant molecules are involved in each steps, therefore, each steps are bimolecular. Since water is in excess, therefore will not be rate law
Rate law for first step:
Rate law for second step:
Rate law for third step:
(d)
Step 2 is slow step, therefore this step will be rate determining step.
So, rate = k [I-] [HClO]
So, it consisted with the actual rate law
