Humans and other mammals breathe in oxygen from the air for respiration. Breathing allows us to pull air into our lungs so that we can use the oxygen it contains. A muscle below the lungs, the diaphragm, contracts and flattens when you inhale. This process the pressure in the lungs, causing external air to rush into the lungs. When the diaphragm relaxes, it pushes against the lungs, this process the pressure inside the lungs and pushes the air out. A) decreases; increases B) decreases; decreases C) increases; decreases D) increases; increases

In a coffee press, you combine solid coffee grounds and hot water. After a long time, the ground coffee beans are still visible, and the water has turned into a rich dark brown (some of the coffee has dissolved into the liquid). You push the filter in the press down and pour out only the dark water into a cup. You then add milk and sugar to the cup. You also notice that the filter must have a hole in it because there are coffee grounds also in your cup. Calculate the degree of freedom in this system (your cup) at equilibrium. 1 2 3 4
The human body burns glucose (C6H12O6) for energy according to this chemical reaction: C6H12O6+6O2→ 6CO2+6H2O The products of the reaction are carbon dioxide CO2 and water H2O Interestingly, all of the carbon dioxide and much of the water exits the body through the lungs: on every breath, the average person exhales 500.mL of air, which is typically enriched to 4% CO2 and 5% water vapor by volume. In short, when a person loses weight by dieting, the weight that is lost actually departs his body as a gas, every time he exhales. Each kilogram of body fat lost requires exhaling about 2.9kg of carbon dioxide. Calculate how many breaths it takes an average person to "exhale" 0.50kg of fat. Round your answer to the nearest thousand. You'll need to know that the density of CO2 is 2.0 kg/m^3 .
The process of liquid water forming from water vapor is an: Endothermic process, because energy is released from the system due to breaking of interactions between water molecules. O Exothermic process, because energy is released from the system due to formation of interactions between water molecules. O Endothermic process, because energy is absorbed by the system due to breaking of interactions between water molecules. O Exothermic process, because energy is absorbed by the system due to formation of interactions between water molecules. MacBook Air DII DD O00 80 F8 F9 F7 F5 F6 F3 F4 & #3 3 4 6. 7 8
According to Wikipedia, Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby, who received the Nobel Prize in Chemistry for his work in 1960. It is based on the fact that carbon- 14 is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting carbon-14 combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire carbon-14 by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of carbon-14 it contains begins to decrease as the carbon-14 undergoes radioactive decay. Measuring the amount of carbon-14 in a sample from a…

A student experimentally determines the gas law constant, R, by reacting a small piece of magnesium with excess hydrochloric acid and then collecting the hydrogen gas over water in a eudiometer. Based L-atm on experimentally collected data, the student calculates R to equal 0.0832 mol·K L-atm Ideal gas law constant from literature: 0.08206 mol·K (a) Determine the percent error for the student's R-value. Percent error = % (b) For the statements below, identify the possible source(s) of error for this student's trial. The student notices a large air bubble in the eudiometer after collecting the hydrogen gas, but does not dislodge it. The student does not clean the zinc metal with sand paper. The student does not equilibrate the water levels within the eudiometer and the beaker at the end of the reaction. The water level in the eudiometer is 1-inch above the water level in the beaker. The student uses the barometric pressure for the lab to calculate R.
When substances are dissolved in water, they can absorb or release heat. Describe how you would use a calorimeter to determine the amount of heat required or released to when 10 grams of sugar is dissolved in 100 grams of water. Describe how you would calculate the heat absorbed or released by the sugar with the data you collect. (Do no perform any calculations.)
Part IV Cabbage Juice Indicator Chop cabbage into small pieces until you have about 2 cups of chopped cabbage. Boil for at least ten minutes to allow time for the color to leach out of the cabbage. Allow it to cool for 15 min • Filter out the plant material to obtain a red-purple-bluish colored liquid. 1. Add 1-2 drops of cabbage juice into a small bowl 2. Add 3-5 drops of vinegar into the bowl with the cabbage juice 3. Observe Is this a chemical change or physical change? Explain? Store the excess cabbage juice in your refrigerator, you will need them for future experiments.
