Does oxygen have a triple bond? Oxygen tends not to form triple bonds due to formal charge reasons. If oxygen starts with 6 electrons and forms a triple bond, then it has 2 lone pair electrons. Using the formal charge formula, 6 – (2+6/2) = 1. Since oxygen is so electronegative, it’ll tend not to […]

How do you know if a relationship is direct or inverse?
How do you know if a relationship is direct or inverse? Direct vs. In direct relationships, an increase in x leads to a correspondingly sized increase in y, and a decrease has the opposite effect. This makes a straight-line graph. In inverse relationships, increasing x leads to a corresponding decrease in y, and a decrease […]
