    I just want to thank you Melissa. I'm a returning adult student and never taken any chemistry. Our professor just talks on an advanced level he doesn't understand that we need it broken down on a simpler level. You are gifted, thank you for getting me through chemistry. If there are a recent spikes in subscribing to your channel it's cause I'm telling everyone in class how amazing your videos are 😜

    What about when you are not given an enthalpy and are only given the temperature change and the mass of water?

    I just want to thank you sooooo much. I have a thermochem test tomorrow, and I had no idea how to do the stoichiometry for the Delta H! Your video literally saved my life! (and hopefully my grade lmao)

    Hi question, just wondering how you figured out where to but the mols when dividing everything. I understand everything else, it just that bit is stumping me. Thank you so much :D

  • @JessicaAbe

    what about when theres an excess?? For example my question is "Calculate how much energy is changed when 16 g of O2(g) reacts with excess ClF3(g)". How do I work in the excess amount? plz answer

    is the answer for the last example letter b, 1340.35 kJ?

  • @blessingosarodion5167
    @blessingosarodion5167 3 роки тому

    Hi, why didn't you change the -1204kj into positive when it was above the 2 moles. I only ask this because I've seen other chemistry videos and they reverse the sign in the stoichiometry process

    How many kilojoules are given off when 17.8 mol of CH4(g) react?
    CH4(g) + 2O2(g) → CO2(g) + 2H2O(ℓ) ΔH = −890.1 kJ please this solve because I don't understand help me

  • @luisdepaz7390

    Thanks for the help! this video actually helped with some of the problems. However, I still can't figure out which conversion factor to use if the given information is volume of methane gas at a certain preassure in Torr and a certain temperature in degrees celcius.

    When multiplying to get both the magnesium and the oxygen to balance out, wouldn't the oxygen change to 4 when you times it by 2?

    • @melissamaribel
      @melissamaribel  5 років тому +2

      Hey Shuat, so we never multiply the subscripts and the coefficient for balancing. The magnesium is the only one that has that 2 in front. I recommend reviewing some more balancing equations, I recommend these videos:
