Question 1 (2 points) A technician mixes a solution containing… Question 1 (2 points)A technician mixes a solution containing silver nitrate with a solution containing sodium chromate. 2.89 g of precipitate is produced. (Hint: use your solubility table to see which product will be a precipitate as this is a double replacement reaction) Calculate the mass of silver nitrate present in the first solution Question 2 (2 points)In a hydrogen fuel cell, hydrogen and oxygen gasses react to produce water vapour. What volume of hydrogen at 40 °C and 150 kPa can be burned in a fuel cell using 300 L of oxygen gas measured under the same conditions?Hint:1. Write out balanced chemical equation2.  Use ideal gas law PV=nRT to calculate the # of moles of oxygen used3.  use the molar ratio of oxygen to hydrogen to find out  the number of moles of hydrogen used4. Use PV=nrt again to calculate volume of hydrogen usedQuestion 3 (2 points)Ammonium sulfate fertilizer is manufactured by having sulfuric acid react with ammonia. In the laboratory, a reaction was done using 50.0 mL of sulfuric acid with 24.4 mL of a 2.20-mol/L ammonia solution. What was the concentration of the sulfuric acid solution?1. Write out balanced chemical equation2. calculate the number of moles of ammonia used. (be sure to change your volume to L before you do this)3. Use molar ratio of ammonia to sulfuric acid to calculate the # of moles of sulfuric acid4. Calculate concentration (mol/L) of sulfuric acid using moles and volume (change mL to L first) Question 4 (2 points) 1.63 g of precipitate is collected from a reaction of a silver nitrate solution with 10.0 mL of hydrochloric acid. Calculate the concentration of a hydrochloric acid solution.1. Write out balanced chemical equation (this is a double replacement reaction, use your solubility table to see what the precipitate is)2. Use mass of precipitate and molar mass to calculate # of moles of precipitate3. Use molar ratio of precipitate to Hydrochloric acid to calculate the # of moles of HCl.4. Calculate concentration of HCl using moles calculated and volume given (be sure to change your volume to L) hhh   Science Chemistry CHEM 208 Share QuestionEmailCopy link Comments (0)

Writing an essay outline is an important step in the writing process. An outline helps you organize your thoughts and ideas, and it makes it easier to write a well-structured essay. Here are the steps to help you write an essay outline like writers do:

Choose a topic: The first step in writing an essay outline is to choose a topic for your essay. It’s important to choose a topic that you are interested in and one that you have enough information on.

Brainstorm ideas: Once you have a topic, brainstorm ideas and jot down notes on what you want to write about. Think about your thesis statement, main points, and supporting evidence.

Create a thesis statement: Your thesis statement is the main point of your essay. It should be clear and concise, and it should express the main idea that you want to convey in your essay.

Organize your main points: Organize your main points into a logical order. Each main point should be a topic sentence that supports your thesis statement. Use bullet points or numbers to organize your main points.

Gather supporting evidence: Gather supporting evidence for each of your main points. This may include facts, statistics, or examples.

Write an introduction: In the introduction, introduce your topic and provide some background information on it. End the introduction with your thesis statement.

Write the body paragraphs: The body paragraphs should each focus on a specific main point. Start each paragraph with a topic sentence that relates to your thesis statement. Provide evidence to support your main point and use examples and personal experience to illustrate your points.

Write a conclusion: In the conclusion, summarize your main points and restate your thesis statement. Provide a final thought or call to action.

Edit and revise: Once you have completed your essay outline, take some time to edit and revise it. Check for grammar and spelling errors, and make sure your ideas flow logically.

Remember, an essay outline is a roadmap for your essay. It helps you organize your thoughts and ideas, and it makes it easier to write a well-structured essay. With these steps, you can write an essay outline like writers do.
