    I am hemi-spherically balanced which means I use both sides of my brain equally which is and advantage when it comes to grasping some form of most kinds of concepts but I cannot use one side more than the other. In other words when I need to do math unless my visual side is stimulated it takes me twice as long as people only using the logic side of their brains. So I need visual representation as well as equations to understand complex concepts. You are the person I needed. Excellent cues make me focus when I need to pay attention to small but differentiating variables. Not to sound crude but there is an audible tone change in your voice. Reminds me of the clickers they use for dogs to get them to focus on the action.(Classical Conditioning) My Stats and Chemistry Professors taught the same dry all left brain way but it took my MFT Professor to teach the way I needed. So I want to thank you for helping me through what is my last class to receive my BS in Psychology. Keep it up...

    LOVE YOUR VIDEOS !!!
    Im wondering if you can help me out with this problem !
    2 H2(g) + O2(g) → 2 H2O(l)
    Suppose we carry out the above reaction with 30.0 g of O2 and 4.00 g of H2.
    (a) Which reactant is the limiting reactant?
    (b) How much of the other reactant remains at the end of the reaction?
    (c) What mass of water is produced?
    In part a - I found that the limiting reactant is oxygen and hydrogen is in excess, can you help me with the other two please?

    What if all you have is mL? And you're looking for moles? Do you get the molarity from the balance equation?

  • @cr125153
    @cr125153 11 років тому

    In the last problem i tried it myself before you would do it and i endid up doing it differently and i dont know if it is right or wrong ?
    here is what i did.
    i tranformed 150ml into 0.15l
    i multiplied 58.5(NaCL) times 3mol =175.5
    and then i divided 175.5 and 0.15= 26.32g

  • @thericate
    @thericate 9 років тому +1

    (you dont have to solve it, just my question in the bottom)
    So what if it asks the molarity of Na+ in the solution when .20 mol of Na2SO4 is dissolved in water to produce 100 mL of solution.
    Do I have to multiply by 2 in order to get the molarity of Na+*

    • @sciencepost
      @sciencepost  9 років тому

      thericate Bingo. Bear in mind that the molarity expressed is for the ionic compound. When it dissociates, you'll have 2x the Na+ ions. In the end, you'll have to divide by the volume to get the molarity.
