You are a meteorologist working with a team researching high altitude wind patterns across the high Texas plains in the winter. Your team is working with high altitude weather balloons and needs to purchase two more balloons for your research. In order to conduct the necessary research, you need one balloon that can reach altitudes of 28,000 feet (around -48.6°C and 0.298 atm on average) and another that can reach 71,000 feet (around -54.1°C and 0.0443 atm on average). Your research of different weather balloon options identifies a balloon that can reach a volume of 95,000 Liters before it bursts. It says that it must be filled to 7,584.4 L of Helium gas on the ground(25.0°C, 1.00 atm) before being released. You will need to produce a report or briefing that will be delivered to your team leader regarding the weather balloon option that you have been researching. Your report should include the following.1. A calculation of the volume of the balloon at 28,000 feet and 71,000 feet.2. An indication of whether the weather balloon would work for your research purposes or not3. An explanation of why the balloon either bursts or remains intact. This should refer to the pressure, temperature, and volume of the gas inside the balloon and outside the balloon and how these variables cause the balloon to burst or remain intact.

Experiment: effect of solution concentration on reaction rate you have learned that as the concentration of reactants increases, there will most likely be a greater number of collisions, and hence increase the rate of a reaction. in this experiment, you will see a demonstration of this, with a twist. there will be three reactions going on in this experiment. objectives determine how solution concentration can affect the rate of a reaction. the first reaction will be a reaction of the iodide ion (i-1) with hydrogen peroxide (h2o2) in an acidic solution. this reaction produces a slightly orange solution. in our experiment, we will add some orange food coloring to make this solution more orange. 2 h+ (aq) + 2 i- (aq) + h2o2 (aq) ⟶ i2 (aq) + 2 h2o (l) the next reaction will be between the iodine and starch i2 + starch ⟶ i2-starch complex (blue-black) so, when starch is added to the iodine solution made from the first reaction, the solution will turn black immediately, so it is difficult to find the rate of reaction. in order to be able to time this reaction, you will slow it down with another reaction. adding ascorbic acid will react with the iodine, reducing the concentration of the iodine available to react with the starch. c6h8o6 (aq) + i2 (aq) ⟶ 2i- (aq) + c6h6o6 (aq) + 2 h+ (aq) when the ascorbic acid is used up, the remaining iodine molecules can react with the starch and form the black color. the more ascorbic acid you add, the slower the reaction to form the iodine-starch complex will be. use your data and observations to complete the assignment. analysis and conclusions submit your data and the answers to these questions in the essay box below. what was your hypothesis? plot your data as drops of ascorbic acid vs. time. as the concentration of ascorbic acid was increased, did the rate of the formation of the iodine-starch complex increase or decrease? explain your answer in terms of the chemical reactions involved. was your hypothesis correct? make a general rule about the effects of concentration of reactants on reaction rates. for practice, the molecular formula for ascorbic acid is c6h8o6, and you used 6 g in this experiment, calculate the molarity of the ascorbic acid. now calculate the concentration in moles per drop (assume 1 ml = 20 drops).

Why is it possible for different microorganisms to extract energy not only from carbohydrates and other biological molecules but from a large variety of substances?

The molecular weight of carbon dioxide, co2, is 44.00 amu, and the molecular weight of nitrous dioxide, no2, is 46.01 amu, so no2 diffuses co2
