What is a mixture? What do you see in the images below that led to your claim? What is it about the evidence that supports your claim? Below is a before and after turning off the mixture button.
To prepare the solution you would place the solute in a 50.0 ml volumetric flask, and then fill to the mark with water while mixing. This would give a total solution volume of 50.0 ml. The 5.0 solution needs to be diluted to make 10.0 ml of a 2.0% solution. What volume of 5.0% solution should be used? Please answer fast i give you upvote.
Which of the following statements is true? After drying a sample in the oven, you can place it immediately inside the analytical balance. In weighing hygroscopic substances, containers should always be kept close when not in use. Place solid reagents / precipitates directly on top of the balance pan. Liquids can be weighed using a weighing paper.
Read the Limit Test for salicylic acid in aspirin below then answer the question below. Remember: Aspirin = acetyl salicylic acid (ASA), and salicylic acid = SA Limit Test for salicylic acid: Extract powdered Aspirin tablets (i.e., active + excipient) containing 0.4g acetylsalicylic acid (i.e., active) with 4 mL of 95% ethanol. Add water to give a final volume of 100.0 mL and mix. Transfer 50.0 mL of the filtrate to a Nessler Cylinder and add 1.0 mL of acidified ferric ammonium sulfate solution. Mix and allow to stand. Prepare the standard solution used for comparison as follows: To another Nessler Cylinder add 3.0 mL of freshly prepared 0.01% (wt/vol) salicylic acid, 2.0 mL of ethanol, 1.0 mL of acidified ferric ammonium sulfate solution and sufficient water to give a total volume of 51.0 mL. Mix. A violet colour produced by the sample should not be more intense than that of the standard, used for comparison. Example of "Limit" calculations: Based on the above limit test, the…
Explain your rationale for using the summative assessment (below) from the lesson plan on mixing substances in a 5th-grade classroom based on the below standard and learning objective, including how it aligns with the learning objective. Summative Assessment Summative: Components of the Lab Report Purpose: The student should clearly state the purpose of the experiment, which is to determine whether the mixing of two or more substances results in new substances. Procedure: The student should describe the steps they took to conduct the experiment. This includes the substances they chose to mix and the safety equipment they used. Observations: The student should record any observable changes that occurred when the substances were mixed. This could include a color change, the formation of a precipitate, or a change in temperature. Conclusion: The student should state whether a new substance was formed based on their observations. They should also reflect on their accuracy in…

The solvent moves 3 cm in about 10 minutes. Why shouldn't the experiment be stopped at that time instead of waiting 75 minutes for the solvent to move 10 cm? Question 3 options: More time increases the concentration of mixture components. More time allows for better separation of components in a mixture. More time decreases the concentration of mixture components. Instructors don't like students to be finishing their labs too quickly.
