What is the formula for tin (IV) oxide?
|
|
Tn4O2
|
|
|
SnO2
|
|
|
SnO
|
|
|
TnO2

Explanation:
Detailed explanation-1: -The formula Sn2O4 is not acceptable because it does not contain the simple whole numbered ratio, and hence SnO2 is the correct one. because Roman numeral II indicates 2+ charges.
Detailed explanation-2: -Tin dioxide is an inorganic compound with the chemical formula SnO2.
Detailed explanation-3: -Tin, as a transition metal, has variable valences and in this reaction has a valence of 4. Oxygen has a valence of-2, so a criss cross of valences gives a formula Sn2O4. This ionic formula is then reduced to lowest terms; the formula for tin(IV) oxide is SnO2.
