Imagine you are looking at a bottle of salad dressing containing oil, vinegar, and water. Why are there two layers in the salad dressing? Water and vinegar are both hydrophobic and mix, whereas the oil is hydrophilic. Vinegar and oil are both hydrophobic and mix, whereas the water is hydrophilic. Water and vinegar are both hydrophilic and mix, whereas the oil is hydrophobic. Vinegar dissolves into both the oil and the water in this container.

In an effort to address concerns about global warming, a power plant in portland,oregon is designed to take all of its exhaust gases from its boilers and recycle the co2 using the solvay process to make sodium hydrogen carbonate. the reaction is shown below. nh3(g) + h2o(l) + co2(g) + nacl(aq) → nahco3(aq) + nh4cl(aq) how many liters each of nh3 and co2 (both at stp) would be consumed to produce 3.00 kg of sodium bicarbonate? the volume of both nh3 and co2 would be

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
