1) for the reaction below, describe the temperature and pressure conditions that would produce the highest yield for the forward reaction. explain your answer in terms of le châtelier’s principle.. n2 (g) + 3 h2 (g) two arrows stacked on top of each other. the top arrow points to the right. the bottom arrow points to the left. 2 nh3 (g) deltah = -92 kj/mol. 2) explain, in terms of particles, concentration, and reaction rate, what you expect to happen when methane gas (ch4) and hydrogen sulfide gas (h2s) are sealed in a flask and reach a state of equilibrium.. ch4 (g) +2 h2s (g) two arrow

Nuclear fusion is the source of energy for stars. besides hydrogen, which other element is most likely also common in stars?

Which of the following statements about hybrid orbitals is or are true? choose all that apply. choose all that apply. under sp2 hybridization, the large lobes point to the vertices of an equilateral triangle. after an atom undergoes sp hybridization there is one unhybridized p orbital on the atom. the angle between the large lobes of sp3 hybrids is 109.5∘

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.
