In this lab‚ we were able to determine measuring the pH of liquids work. We were able to compare the liquids based on their pH level and determine which liquid was acidic or basic. Our results showed that if something came out to be seven or less‚ according to the pH scale‚ it means that an acid is a substance that donates hydrogen ions. Because of this‚ when an acid is dissolved in water‚ the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide

Lab 7: Geologic Time 9 Answer Sheet Name(s) 1. As an example of how radioactive decay works‚ the TA may lead a small demonstration. Each student will receive one penny and stand up. At this point all of the students are parent isotopes. Every student should then flip their penny. Students whose penny lands heads-up should sit down. These students who are now seated are now daughter isotopes. The remaining standing students should again flip their penny‚ and students whose penny lands heads-up

How much available shrink space is contained in the volume? 449MB 6. How is the last volume you created different from the previous ones? Explain why. The size of the volume is different. By shrinking the file it made the volumes less than 2000MB 7. What do you suppose would happen if you created another simple volume out of the free space left on the disk? I think that the it will run out of recourse. 8. Were you successful? No‚ The extend option is grayed out. 9. What is the result? It was

1. What are some common risks‚ threats‚ and vulnerabilities commonly found in the LAN-to-WAN Domain that must be mitigated through a layered security strategy? A layered security strategy will encompass Rouge protocols such as Bit mining and P2P‚ Unauthorized network scanning and probing‚ and unauthorized access to the network. 2. What is an Access Control List (ACL) and how is it useful in a layered security strategy? An ACL is a Control list which will allow or deny traffic or devices based on

The reason why I think this could be a limitation is because each solution has an extreme acidic pH level like 1 or 2. As a result‚ I speculate the supreme acidity of the solution could negatively affect the pH measurer that could make it lose the originality to measure the right pH level for later product. Hence‚ it is crucial to have the pH measurer calibrated in a buffer solution so that the measurement can have a high accuracy overall. Thirdly‚ when measuring the

Introduction: The purpose of this experiment is to test if altering the pH of the milk will trigger a hydrophobic reaction. It will also give me a better understanding of the scientific method‚ hydrophobic reactions‚ and how pH affects substances. If the vinegar and salt are added to the heated milk‚ then the milk will curdle. I came to this conclusion based on common knowledge and the text introducing the experiment. I have not made cheese at home before‚ but I have made Hamburger Helper meals

pH indicators‚ in chemistry‚ are usually a weak acid or base that are naturally occurring in various plants and flowers and can act as dyes. Some examples of indicators are Litmus (Comes from a plant species called a lichen)‚ Phenolphthalein‚ Thymol blue‚ Bromocresol green and Universal indicator. All these indicators have a certain turning point in color once a certain concentration equilibrium of Hydrogen cations in reached (H +) or a certain concentration equilibrium of H3O+(Also OH - using Arrhenius
