Which of the following are least reasonable regarding the chemical composition of our solar system? Group of answer choices Hydrogen and helium are the two most abundant elements in our solar system. There is a lot of iron on Earth but none in the Sun. There is relatively little hydrogen in the Earth's atmosphere because Earth's gravity is not strong enough to hold on to it. There is a lot of oxygen in the Earth's atmosphere due to the activity of

Pretend that you are an atom of nitrogen that lives in the atmosphere. Describe at least six steps of your journey through the nitrogen cycle. Explain why the journey of another nitrogen atom is different than your journey.

Which two correctly relate the attraction between the particles of a liquid and the temperature at which the liquid changes state? A. Strong attractions mean the liquid melts at a lower temperature. B. Strong attractions mean the liquid boils at a higher temperature. C. Strong attractions mean the liquid boils at a lower temperature. D. Strong attractions mean the liquid melts at a higher temperature.

picture of filling station This convenience store and filling station supplies 22,680 gallons of gasoline per day to central Pennsylvania residents. How many megawatts of chemical energy is this station putting out over the course of the day? Each gallon of gasoline contains 125,000 BTUS, each BTU/minute equals 17.58 watts.

Some of the following sources listed are currently used, while others might be more feasible in the future with more research.  Fossil fuels Nuclear energy Biofuels Wind energy Solar energy You will research how the energy is extracted or produced and try to be very detailed about the process and the chemistry involved (stating equations and reactions). You will also research the impact on the environment when using or producing fuels.   Investigating fossil fuel: How is it produced? What is the chemistry involved (stating equations and reactions)? What is the impact on the environment? Investigating nuclear energy: How is it produced? What is the chemistry involved (stating equations and reactions)? What is the impact on the environment?

Four tiny spheres are fastened to the ends of two rods of negligible mass lying in the xy plane to form an unusual baton (as shown). We shall assume the radii of the spheres are small compared with the dimensions of the rods. (A) If the system rotates about the y axis (10.19a) with an angular speed ω, find the moment of inertia and the rotational kinetic energy of the system about this axis. (B) Suppose the system rotates in the xy plane about an axis (the z axis) through the center of the baton (10.19b). Calculate the moment of inertia and rotational kinetic energy about this axis.
