Answer:
Pb(s) ---> Pb+2 + 2e- is the anode
Cu+2(aq) + 2e- ---> Cu(s) is the cathode
Answer:

one atom of an element = 6.02 \times {10}^{23} atom
The mass of one atom of sulphur = 32g
The mass of one atom of aluminium = 27g
so one atom of aluminium = 6.02 \times {10}^{23}
27g of AL = 6.02 \times {10}^{23} atom
2.70g of AL = X atoms
Then you cross multiply ........
and get the answer
.
Best Answer:<span> </span><span>Bromate ion is BrO₃⁻.
In each hypobromite ion, there are 2 oxygen atom less than bromated ion.
Therefore, hypobromite ion is BrO⁻.
...... The answer is : a. BrO⁻

I can’t answer the exact thing, but I know how to do it. One of the nitrogen bases always pairs with a different one, so once you know what pairs with what you just write it down. If you need more help just ask :) tip: one base will only join with a different one. One won’t join to multiple (from what I know as of now)
<span>The Representative elements are the first two relations and the last six relations of the Periodic Table. The Transition elements are in three series in periodic table and they all are metals.
therefore,
</span>A) lithium is <span>Representative element
</span>B) platinum isTransition element
C) promethium is<span>Transition element
</span>D) carbon is <span>Representative element</span>
