Part C You need to prepare a 2.40 M solution of sodium hydroxide (molar mass of sodium hydroxide = 40.00 g/mol ), but you only have a 10 mL graduated cylinder and a 25 mL beaker. Complete the following sentences regarding the concentration of the prepared solution. Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer. • View Available Hint(s) Reset Help greater than 10.0 mL 1. In order to prepare 10.0 mL (0.0100 L) solution of 2.40 M sodium hydroxide, a mass of would be required. exactly 10.0 mL exactly 2.40 M 2. When the solute and a total of 10.0 mL of water are both added into the beaker and stirred until 0.024 g the solute dissolves, the solution volume will be greater than 2.40 M 3. Based on that, the concentration of the prepared solution will be less than 2.40 M. less than 10.0 mL 0.960 g P Pearson

2. For his second experiment, Samuel uses vinegar instead of acetic acid powder. He sets up three experimental trials with different reaction conditions. He records all his data in the table below for the three trials. Trial Mass of Baking Soda (g) Temperature (°C) Volume of Vinegar (ml) Reaction time to completion (s) 1 10.0 25.0 60.0 41 2 10.0 40.0 60.0 23 3 10.0 55.0 60.0 12 b) Explain the reason for the pattern in Samuel's results. Your explanation should refer to what is happening between the reactant particles.

Can you help me filling all the  table with this data please I really appreciate it! Titration of Acetic Acid and Vinegar - Topic

O Cr O H,O O Mg Figure I Figure 2 Two samples of Mg(s) of equal mass were placed in equal amounts of HCI(aq) contained in two separate reaction vessels. Particle representations of the mixing of Mg(s) and HCI(aq) in the two reaction vessels are shown in Figure 1 and Figure 2 above. Water molecules are not included in the particle representations. Which of the reactions will initially proceed faster, and why? The reaction in Figure 1, because the atoms of Mg are more concentrated than those in Figure 2 The reaction in Figure 1, because the Mg(s) in Figure 1 has a larger mass than the Mg(s) in Figure (B 2 The reaction in Figure 2, because more Mg atoms are exposed to HCI(aq) in Figure 2 than in Figure 1 The reaction in Figure 2, because the Mg(s) in Figure 2 has less surface area than the Mg(s) in

*** this is not a graded assignment, I am double checking my answer key please. A vessel of calcium chloride solution (CaCl2) (2 Ca ions and 4 Cl ions represent a .1 M solution)  is mixed with  potassium carbonate (K2CO3) which should be drawn as .2M .Draw the reactant with the appropriate amount of K2CO3 particles in an empty box. The product calcium carbonate (CaCO3) forms a precipitate. Draw the appropriate example of the precipitate and the ions that remain in the solution. Add two water molecules around each ion in the solution.

Sodium carbonate dissociates when it dissolves in water as follows:   If the concentration of the sodium ions is 0.817 mol/L, then what is the concentration of the sodium carbonate solution? Record only your numerical answer with the correct number of significant digits.  You do not need to include units as the units appear for you beside the answer box already.

Your lab assignment presentation involves putting together a presentation to show other students on how to perform titration. In other words, your presentation can be used to show other students (next term) how they can perform a titration by following your instructions and calculations. To do this presentation, we are giving you the type of acid, acetic acid, the type of base, NaOH to be used, and you will use phenolphthalein as the indicator. You will use the data given to you to be used as an example of how to solve the mathematical calculations. At the end of your presentation, you will show the unknown concentration of the acetic acid (Molarity) and will also show the % mass/ vol of the Vinegar solution. Part 1 Purpose of a titration, what is titration and why do we perform a titration? Instrumentation- what are the instruments, glassware used when performing a titration. Chemicals and Procedures. What chemicals are needed? List and explain the procedures for this experiment.…

Solubility is the ability to dissolve certain substances(solutes) into a solvent. You are a student in Mrs. Bateast's Chemistry class and you were given the assignment to compare solubilities of salt in different solvents at different temperatures. You added salt at a consistent rate and amount until you reached the point of full saturation. The amount added to each solvent at saturation was recorded. The results of the experiment are shown in the tables: Table 1: 20 °C Mass of Salt at Saturation 43 g 38 g 0.01 g 3 g Solvent Water Ethanol Hexane Dichloromethane Table 2: 35 °C Solvent Water Ethanol Mass of Salt at Saturation 52 g 45 g 0.02 g 4g Нехane Dichloromethane Using CER and your knowledge from data listed above, if the temperature of ethanol solution increased by an additional 10 degrees, what would happen? Construct a line graph is required as well.
