CaSO4 + AlBr3 > CaBr2 +Al2(SO4)3 What will the coefficient of CaBr2 when the equation is balanced using the smallest possible whole number coefficient

The coefficient of CaBr2 is 3

Explanation:

Step 1: The unbalanced equation

CaSO4 + AlBr3 → CaBr2 +Al2(SO4)3

Step 2: Balancing the equation

CaSO4 + AlBr3 → CaBr2 +Al2(SO4)3

On the left side we 1x SO4 (in CaSO4), on the right side we have 3x SO4 (in Al2(SO4)3. To balance the amount of SO4 on both sides, wehave to multiply CaSO4 by 3.

3 CaSO4 + AlBr3 → CaBr2 +Al2(SO4)3

On the left side we have 1x Al (AlBr3) and on the right side we have 2x Al (in Al2(SO4)3. To balance the amount of Al on both sides,we have to multiply AlBr3 on the left side, by 2.

3 CaSO4 + 2AlBr3 → CaBr2 +Al2(SO4)3

On the left side we have 3x Ca (in CaSO4), on the right side we have 1x Ca (in CaBr2). To balance the amount of Ca on both sides, we have to multiply CaBr2 on the right side, by 3. Now the equation is balanced.

3 CaSO4 + 2AlBr3 → 3CaBr2 +Al2(SO4)3

The coefficient of CaBr2 is 3

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
