  1. Hmm ok, for the homogenous mixture of the solid and liquid, would salt water, or sugar water work? I was concerned that it might not, seeing as the salt/sugar is actually dissolved...
  2. Ok I think I've found everything, but I'd like to check my answers...If that's ok: 1) 0.58 moles of Sodium Bicarbonate A: 48.73 grams of Baking Soda 2) A sample of the element that requires 12 more electrons to achieve the electron configuration of the 4th period noble gas. A: Chromium: Stainless Steel 3) The amount of air that would contain the exact amount of nitrogen gas that would combine with 1.0 gram of hydrogen to produce ammonia. A: N - 78% of air so: 5.927 grams of air (after calculations) 4) A ternary compound that contains a halogen. A: Bleach: Sodium hypochlorite: NaOCl 5) "Something" that will demonstrate the conversion of rotational energy to wave energy. A: A fan (Fan blades rotate and you can hear the noise they make (wave energy)) 6) Demonstrate a neutralization reaction. Write a balanced equation for the reaction. A: Baking soda (NaHCO3 ) and vinegar (CH3COOH ): CH3COOH + NaHCO3 -> H2O + NaOCOCH3 + CO2 7) A homogenous mixture of a solid and a liquid. A: Milk: solid fat globules dispersed throughout 8) SiO2 A: Quartz: Dendritic Quartz 9) A system at physical equilibrium (physical meaning different phases) that involves a solid. A: Saturated sugar water Are these all correct? Thank you for your time
  3. Sodium hypochlorite? I took a look at my bleach down in the laundry room and saw that. Does that fit? NaOCl
  4. Ok I'm not sure if this is alright, but I was hoping I might be able to have a little bit of help finding some items for a chemistry class. The only one I need help with right now is: 1) A ternary compound that contains a halogen
