What does it mean to make an absolute identification of your unknown liquid?
I believe that it means that your analysis of your data enables you to absolutely identify your unknown liquid as that specific liquid and no other liquid.
Suppose you were given an unknown liquid and asked to determine if it was an element a compound or a mixture What would you do How would this help you find out what it was?
If I was given an unknown liquid and asked to determine if it was an element, a compound, or a mixture I would heat the unknown liquid up to see if any compounds separated from the unknown liquid. After that I would get a microscope and look to see if it is a pure element. Then I would get a Platelet separation machine and put the liquid in the machine to see if the liquid separated. Thats how I would determine if the an unknown liquid is an element, a compound, or a mixture.
Does the unknown planet have a liquid region in its interior?
I don't know, the planet is unknown.
Is the dispersed phase in the colloid known as mayonnaise a gas or a liquid or a solid or is it unknown?
It's a liquid.
How do you find the density of liquid?
Problem: You are given two unknown liquids. Find the density of each. Materials: 100ml graduated cylinder, triple beam balance, calculator, 2 unknown liquids. Procedure: 1) Find the mass of the empty graduated cylinder. 2) Pour unknown liquid #1 into the graduated cylinder to the 50 ml. level. 3) Find the mass of the graduated cylinder with 50ml of unknown liquid #1. 4) Repeat steps 1-3 for unknown liquid #2. We can calculate density of a liquid using the formula: Density= Mass/Volume where mass is that for just the liquid (you must subtract out the mass of the graduated cylinder). Now let's calculate the densities of the two liquids using the following given data. Liquid #1: Given: Mass of empty graduated cylinder = 78 grams Mass of graduated cylinder with unknown liquid #1= 128 grams. Find: a) Mass of just the liquid = ____ b) Volume of liquid=_____ c) Density of liquid #1 =____ Liquid #2: Given: Mass of empty graduated cylinder = 78 grams Mass of graduated cylinder with unknown liquid #2= 117.5 grams. Find: a) Mass of just the liquid = ____ b) Volume of liquid =_____ c) Density of liquid #2=____ Check your answers by inserting the value in the box below.
How does red cabbage indicator work?
A red cabbage indicator is a liquid made from mashed up red cabbage which you then put in a liquid to see whether it is acidic or not. If it is acidic the liquid would turn reddy orange and if it was an alkali ( the opposite to acid) it would turn purpley blue. This is if the liquid was clear in the first place.
When making red cabbage indicator why do you grind the cabbage rather than stir it?
It is important to release a liquid.
What is the density of the unknown liquid rho unknown?

How will you determine when the unknown liquid in the flask has completely vaporized?
The unkown liquid in the flask has completely vaporized when there is no liquid in the flask.
What if an empty graduated cylinder weighs 51.36g. When filled with 50.0mL of an unknown liquid. it weighs 91.35g. What is the density of the unknown liquid?
A gram is a measure of mass, not of weight. The density of the liquid is 0.8 grams per mL.
