Determine chemical or phisical property

The bronze color of copper

The ability of sulfuric acid to burn the skin

The boiling point of water

The smell of a perfume

The tendency of silver to tarnish

Homework Answers

Answer #1

The bronze color of copper --> this is physical appeareance, this is due to the electromgnetic spectrum

The ability of sulfuric acid to burn the skin -> this is chemical reaction, since it makes a chemical change to skin

The boiling point of water --> this is a physical property, since it will remain being water/vapor

The smell of a perfume --> this is physical appereance, since it is a property of a chemical compound

The tendency of silver to tarnish --> this is chemical property, menaing that silver will form Ag2S compound whit dust and time

Procedure Reaction 1: Dissolving the Copper 1. Obtain a clean, dry, glass centrifuge tube. 2. Place a piece of copper wire in a weighing paper, determine the mass of the wire and place it in the centrifuge tube. The copper wire should weigh less than 0.0200 grams. 3. In a fume hood, add seven drops of concentrated nitric acid to the reaction tube so that the copper metal dissolves completely. Describe your observations in the lab report. (Caution, Concentrated nitric...

Preparation of acetyl salicyclic acid (Aspirin) post-lab questions 1.) The FeCl3 test you performed on salicylic acid, crude aspirin, and the purified aspirin gave different colors. Comment on the results you obtained in each of these tests in terms of colors and the functional groups present and what does that indicate about the purity of your purified aspirin? I got a dark purple color for saliclyc acid tube. "dark yellow" for crude aspirin tube, "llighter yellow" color for aspirin tube...

Acid-Base Behavior In addition to following the general safety rules, chemicals need to be handled properly. In particular, two very important classes of compounds called acids and bases require special attention. These compounds are commonly used reagents in the laboratory; therefore, understanding their proper disposal is beneficial. Physical differences between acids and bases can be detected by the some of the five senses, including taste and touch. Acids have a sour or tart taste and can produce a stinging sensation...

I have provided the information for the lab below. I want to see the chemical reactions that take place during each step of the experiment. So in the procedures when a chemical was added i would like to see what the products and byproducts that were formed. I also want to see one over all reaction for this experiment to just get an overview of what exactly is happening during the experiment. Thank you:) Part B: Synthesis of [Co(NH3)5Cl]Cl2 Objective:...
