Please help me write a portfolio. GIVING BRAINLIEST 10 POINTSFinish drafting a research report about how scientific knowledge has changed over time. Review the web you completed in the prewrite stage.

You will submit your research report draft at the end of this lesson.

Review the features of a research report:

It provides information focused on a central topic.

It has an introduction that presents the main ideas of that topic.

It groups related facts, definitions, quotations, details, and other information into supporting paragraphs.

It uses content words and has a formal tone.

It uses linking words to connect ideas.

It provides a conclusion that relates to the topic.

It includes multimedia elements such as audio recordings or visual displays.

It contains a bibliography at the end.

Water molecules have a strong attraction to each other because of hydrogen bonding, allowing water to move against gravity up a plant's stem through capillary action. true false

Problem #3 (ch. 1, problem 15)the ideal gas law provides one way to estimate the pressure exerted by a gas on a container. the law isí‘ťí‘ť=푛푛푛푛푛푛푉푉mo re accurate estimates can be made with the van der waals equationí‘ťí‘ť=í‘›í‘›í‘›í‘›í‘›í‘›í‘ ‰í‘‰â’푛푛푟푟â’푞푞푛푛2í‘ ‰í‘‰2where the term nb is a correction for the volume of the molecules and the term an2/v2is a correction for molecular attractions. the values of a and b depend on the type of gas. the gas constant is r, the absolutetemperature is t, the gas volume is v, and the number of moles of gas molecules is indicated by n. if n = 1 mol of an ideal gas were confined to a volume of v = 22.41 l at a temperature of 0â°c (273.2k), it would exert a pressure of 1 atm. in these units, r = 0.0826.for chlorine gas (cl2), a = 6.49 and b = 0.0562. compare the pressure estimates given by the ideal gas law and the van der waals equation for 1 mol of cl2 in 22.41 l at 273.2 k. what is the main cause of the difference in the two pressure estimates, the molecular volume or the molecular attractions?
