If an element is written with a plus (+) or minus (-) symbol in the superscript then the element is either an anion or cation ( ion)

Ex : H₂ -----> stable or elemental form

Na⁺------> Cation

Cl⁻------> Anion

Technically an atom have positive charge when it loses its valence electrons and negative charge when it gains  electrons.

CaSO4 + AlBr3 > CaBr2 +Al2(SO4)3 What will the coefficient of CaBr2 when the equation is balanced using the smallest possible
Deffense [45]

Answer:

3 will be the correct coefficient of CaBr2

Explanation:

In balancing a chemical equation, numbers should be assigned to both reactants and products as a numerical coefficients until all atoms of elements in both sides of the equation count equal.

The balanced equation of the reaction will be:

3CaSO4 + 2AlBr3 ==> 3CaBr2 + Al2(SO4)3

Looking at the unbalanced equation in the question, in the product Al2(SO4)3 there are 3 SO4 group. This will warrant putting 3 behind CaSO4 in order to balance the atoms of SO4 group. That operation will automatically put the number of Ca atoms in CaSO4 to be 3 therefore making CaBr2 to have 3 coefficient as in the balanced equation. This is to balance the number of Ca atoms in both sides to be 3.
