2BF₃ + 3Li₂SO₃ ----> B₂(SO₃)₃ + <u>6LiF

C
Decomposition is of this form: A becomes B+C ... so after the reaction, the element A DECOMPOSES into two smaller elements, B and C.
Synthesis is the opposite: B+C becomes A AFTER THE REACTION.
Hope that helps :))
Chemical energy to thermal
This set up of a conversion table should show you that if you multiply
the grams of BeI2 times .02 moles, it equals <span>5.256 g (your answer) </span>
Answer:
57.6g
Explanation:
So, if in one mole of water, 16 g of oxygen atom is present. Then, in 3.6 moles of water, the mass of oxygen present will be 3.6×16=57.6g. Therefore, the amount of oxygen present in 3.6 g water is option (B)- 57.6 g.
