<span>Best Answer: Mn(ii) is catalyst
Stetep-1 is slow step
Steps-2,3 are fast steps
intermediates are Mn(iii)and Mn(iv)
since step -1 is slow rate depends on Ce(iv) and Mn(ii) only
not on Tl(i) as it is involved in fast step-3</span>
I think the answer is true
Answer:
The solution is 50 %wt
Explanation:
50% wt is a sort of concentration and means, that 50 g of solute (in this case, the potassium bromide) dissolved in 100 g of water.
It is the same to say, that there are 50g of KBr for every 100g of H₂O
A water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structureis bent. This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons.
