Carbon dioxide (co2) is the gas that is mainly responsible for global warming (the greenhouse effect). the burning of fossil fuels is a major cause of the increased concentration of co2 in the atmosphere. carbon dioxide is also the end product of metabolism (see sample problem 3.4). using glucose as an example of food, calculate the annual human production ofco2ingrams, assuming that each person consumes 5.0×102g of glucose per day, that the world's population is 6.5 billion, and that there are 365 days in a year.

Compare and contrast the bohr model and the electron cloud models of the atom.

98 points you will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. before you conduct your experiment, you need to form a hypothesis. a hypothesis is a prediction of what you think will happen in the experiment. the hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur. record your hypothesis here: record the results from step one of the experiment (dropping the objects in the air): first trial: second trial: third trial: record the results from step two of the experiment (dropping the objects in a vacuum): first trial: second trial: third trial: did the experiment support your hypothesis? using the data from your experiment, describe why you believe your hypothesis was either proven or disproven. what forces were acting on the objects dropped in the air? what force was acting on the objects dropped in the vacuum? part two: comparing forces choose two forces and compare and contrast these forces. you must provide two ways that they are alike and two ways that they are different. you may make a list, write in paragraph form, or make a chart. choose two forces and compare and contrast these forces. these must be different forces than used in the prior question. provide two ways that they are similar and two ways that they are different. you may make a list, write it out, or make a chart.
