  1. I have an idea, how about adding Economics category? Thanks for any considerations.
  2. 80+ degrees, really? Are you sure you're keeping the thermostat down? It has to be your room/house/apartment, not your devices.

    Ok, So I've completed the question #8 from textbook. What I'm confused about is question #9. Here is the question 8. #8. For each substance below, identify it as ionic or molecular. Explain how you came to your conclusion. a) Compound 1: melting point: 48C, low solubility in water, flammable, mild odour, colourless solid easily crushed My answer: molecular - because of low melting point b) Compound 2: melting point: 800C, highly soluble, solution is highly conductive, hard, white crystals My answer: ionic - because of high melting point + tight crystal structure

    Is it possible?

    So increasing cholesterol can contribute to the stoppage of heart rate? Does coffee contain cholesterol? Say if I drink 20 cups of coffee and run fast full speed, it will make my heart stop?

    Why not? We live in a system of slavery and greed. It's hard to believe that it's actually hard to kill myself, we have strong survival instincts and such. We only exist so others can profit from us.
  6. I swear I'm going to kill myself if I don't understand some parts of science I'm studying...

  7. Maybe it has something to do with electrons or just charges aren't right.

    Ionic bond

    So, I'm trying to draw a diagram for ionic bond, the question asks me to choose two atoms that could participate, and draw the valence shell I chose Mg and S. So, Mg has 12 protons and 12 electrons, and 2 valence electrons. S has 16 protons, 16 electrons and 6 valence electrons. In the diagram, I drew two atoms with 3 shells, and I will draw an arrow pointing the electron transferring to S shell from Mg's outer shell. How does that sound? Only one electron is transferred to S shell, is this correct? Or two? Because in Mg's outer shell there are 2 valence electrons... Tha

    How come....

    Okay guys, I think you all nailed this thread pretty much. Thanks!

    In my textbook, given example, it says: Write the name of the compound that has the formula Cu3N(s). 1. Identify the ions that form the compound Cu? copper ion, N3- nitride ion 2. Use the charge of the nitride ion (3-) and the rule that the total positive and negative charges in the formula unit must be equal. Three copper ions are present in the formula unit so each must have a charge of 1+. 3. Write the name of the compound. The name of the compound is copper (I) nitride. So, according to #2, I don't get the "rule", how would I determine this? How are thr

    How come....

    How come we don't have walls anymore like those in medieval ages cities had? Imagine with all the technology today and knowledge, we probably could build the strongest one than ever before made...

    So, Cu2S would be called Copper (I) Sulfide? Why would CuS be called Copper (II) Sulfide? Why? Would I have to figure out some ratio for both elements? Sorry, I'm trying not to be confused and am attemping to see a pattern here... Thanks for replies, gentlemen.

    I'm trying to figure out the name for this formula, Cu(bottom 2)S, would it be called Copper (II) Sulfide or just Copper Sulfide? Seeing that Copper has two charges, 2+ and 1, and Sulfur has only 2-. Thanks!
