    This is a good video explaining the concept of formal charges. Are there more such examples around?

    Even though they have a different formal charge they're still the same chemical right? If we were to some this up to a complete mathematical equation they would both come out to zero. I guess the point I'm trying to make is what use do we get out of a set up like this?

    In the first structure, how does the last oxygen have a formal charge of-1? Because it can’t have 7 electrons in the outer shell and the octet rule is not satisfied

    • @optimus2008

      Actually, there are elements which are stable despite not obeying the octet rule. That's why the rule is discarded in higher classes, so we study about hybridisation.

      It does have 8 electrons in its valence shell (6 lone pair electrons + 1 single bond (2 electrons))so its octet rule is satisfied however it has only 7 of those electrons allocated to it due to the fact that you take 1/2 of bonded electrons so its 6 lone pair electrons + 1 electron from the single pair so its 7.

    can anyone help me in this problem ?
    A driver at 25 m / s detects an obstacle in his lane. Braking starts at a distance of 83 m. At a distance of 23 m, a speed of 13 m / s remains. The speed is expected to decrease steadily.
    a) What is the absolute value of the acceleration of the car? Give the answer with three significant digits.

    • @oshmi5398
      @oshmi5398 Год назад +1

      You need to use the formula v^2-u^2=2as here, v is 13m/s and u is 25m/s. 'S' is the distance and 'a' is acceleration. Acceleration in this case will have a negative value (retardation)
      Wait, I just realised that this comment was posted 3yrs ago😅
