    How does the last one have dipole dipole if the center does not have any lone pairs?

    • @dr.stepheng.prilliman8726
      @dr.stepheng.prilliman8726 6 месяцев назад

      Lone pairs on the central atom are often but not always present in a molecule with a permanent dipole moment. H2CO has a dipole because H and O have different electronegativies. Since O has a greater electronegativitiy than H, it draws shared electrons toward it more strongly from the C than do the H atoms. This means there is greater electron density on the O side of the molecule, creating a dipole moment. Hope that helps!

    okay but what if its office 365 excel? i am having the hardest time even finding similar options and tabs needed and the value inputs seem to not let me add values exither. and these wierd red blue and purple boxes appear around some of my selected values.

    • @dr.stepheng.prilliman8726

      My understanding is that the Office 365 version of Excel does not support this function. I usually recommend my students who only have Office 365 access use Google sheets for this instead. See this video for Sheets instructions: ruclips.net/video/rJXz1qVYFu4/видео.html

    • @dr.stepheng.prilliman8726
      @dr.stepheng.prilliman8726 8 месяцев назад

      House plants are outside my expertise but I will say that the water you add to the plants will warm to room temperature so you won't have a temperature effect. But the acid to base balance of the water remains the same (acidic, in your case) regardless of the temperature.

    Can you give the reaction plz?

    • @dr.stepheng.prilliman8726
      @dr.stepheng.prilliman8726 Год назад

      When we write a reaction equation for this we treat this as the dissociation of acetic acid: HCH3COOH (aq) <=> H+ (aq) + CH3COO-(aq) From a Le Chatelier perspective you would say that the addition of sodium acetate increases the acetate (CH3COO-) concentration, and to relieve that addition of a product the reaction goes in reverse. Going in reverse also uses up H+ ions, therefore the pH increases.

    IF the water is not acidic at that temperature then what is the purpose of doing this calculation? What does a pH of 6.3 represent here then if it is not acidity? Please explain!

    • @dr.stepheng.prilliman8726
      @dr.stepheng.prilliman8726 Год назад

      Only at 25 Celsius is 7 the dividing line between acidic and basic. As temperature increases and water autoionized more, the dividing line between acidic and basic decreases. So if you get a result of 6.3 from this calculation, it means that pH below 6.3 is acidic and pH above 6.3 is basic at that temperature.

    thanks for this, I was wondering what was up with the fact that the pH and pOH both appear to be disagreeing when solving for these at different temperatures and now it makes complete sense. basically, the scale itself is changing and the neutral point is no longer 7 at non standard temperatures.
