The following is a backscattered electron image of a sample of nickel alloy particles that were embedded in a resin, cut, and then polished to reveal the internal structure of the particles.        From the image, explain whether you think the alloy has uniform composition or whether it is segregated into phases of different compositions. The resin used for embedding is an electrical insulator. How should such samples be treated before they are examined by SEM?

if you used 1g of the starting material compound 2, how many mmoles is this?

Check this and please answer it as soon as you can. It's very important. If you do help me, i will defitinely consider giving thumbs up https://drive.google.com/file/d/1mN-k-am1ILxrEOzVQ-8kLtrv5vK8HFvw/view?usp=sharing

Having too much sample can cause an inaccurate melting point under these Sir how will the observed melting point compare with the true melting point ?

Course Activity: Identifying a Substance by Its Properties ubstance 9 of 10 SU0odsagen aic uno container labeled water, and pour one tablespoon (15 mL) of alcohol into the container labeled alcoho Note that you now have three containers labeled unknown, water, and alcohol. For Part A Water and rubbing alcohol have distinct properties and will react differently with the same substance. Observe these properties of water and rubbing alcohol: color, smell, and ability to dissolve salt. Record your observations in the table. To observe the solubility of salt in the liquid, put one-quarter teaspoon of salt into each container and stir. You may weigh out 1.5 g of salt on the electronic balance if you don't have a one-quarter teaspoon measure. nents BIUX' X, Font Sizes A 三 三 耳昌 三 三 Water Rubbing Alcohol Color Smell Solubility of Salt Characters used: 60 / 15000

4) In general, if the viscosity is very high at the melting position of the corresponding crystalline phase which would form the melt, it is much easier to form glass for this melt. True or False 5) The glass fiber is possible to have a tensile strength even larger than that for iron or structural steel. Therefore, in the practical applications, we should be able to use glasses for the same purposes of the iron or structural steel. True or False

What will happen during melting point determination if air is trapped in the sample? Mark all that apply. Start of the melt may be hard to determine with a loosely packed sample It takes longer for the sample to melt and may exhibit a mistakenly broad range of melting It takes longer for the sample to melt and may exhibit a mistakenly sharp range of melting The air is not a good conductor of heat, so the heat will not be evenly distributed h
