  • Online Middle School Chemistry Resource

    Updated: 2023-09-30 19:37:08
    The ACS Education Division has developed a new middle school chemistry resource, "Middle School Chemistry: Big Ideas about the Very Small." This free, six-chapter resource can serve as either a stand-alone chemistry unit or as a supplement to any middle school science curriculum. "Middle School Chemistry" uses a hands-on inquiry approach along with specially designed molecular model animations, to take students from concrete experiences to an understanding of the world of atoms and molecules. Share this free resource with middle school teachers you know.

  • Freeze faster ice cream and others

    Updated: 2023-09-30 14:12:57
    Hello nice people!The original query by nareshkumaran was about producing water ice, and I answered with that in mind, but the apparatus I proposed is more general. Sketch there, explanations earlier: bsp chemicalforumsIntuitively, the market for ice cream exceeds that for water ice. Other food is frozen beyond ice cream, and other materials beyond food.Marc Schaefer, aka Enthalp

    Yes, you need more water and less solid when starting from the anhydrous salt. This can be easily calculated - first step will be to find out (using molar masses of sodium acetate and water) how much water is present in the 160g of CH3COONa·3H2O.

  • sodium acetate supersaturated solution

    Updated: 2023-09-30 06:25:49
    hi guysI want to do the instant freezing experiment with sodium acetate super saturated solution. I need sodium acetate 3.H2O for this reason but instead I have anhydrous of this salt. I wanted to ask do I have to add more water to see the results, and if so, how much more?(for sodium acetate 3.H2O I have to add 160 gr sodium acetate 3.H2O with 30 gr of water to achieve supersaturated solution)thanks for your help in advance

  • Energy in microstates

    Updated: 2023-09-30 02:56:41
    Hi, I was just wondering the purpose of this question specifying that the orientations in the microstates are of the "quotsame energy"quot?Calculate the entropy of a sample of a solid in which the molecules may be found in any one of three orientations with the same energy. Suppose there are 30 molecules in the sample.Why is this important? If the orientations were of different energies, would the Boltzmann formula be invalid?Thank
