Answer
Explanation:
Step1: Determine tungsten's oxidation state
In $WO_3$, oxygen has an oxidation - state of - 2. Let the oxidation state of tungsten be $x$. Using the rule that the sum of oxidation states in a neutral compound is 0, we have $x+3\times(- 2)=0$.
Step2: Solve for tungsten's oxidation state
$x - 6 = 0$, so $x = +6$.
Answer:
Tungsten(VI) oxide
