How do you experimentally determine the pressure of the unknown when its a gas?
You can use a manometer.
How do I know if it's a sperm stain or something else?
Unknown substances can be analysed by a chemist.
What unknown metal displaces aluminum from solution but does not displace sodium Using the activity series determine the unknown metal?
magnesium
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.
How do you use density to identify an unknown object?
yes, very often its one of the best things to messure things with. Didn't you pay attention in 6th grade scinence?
Knowing the solubility of an unknown substance in water can help to identify what it is.?
Knowing the solubility of an unknown substance in water can help you calculate its molarity. It is however important to get its weight first.
What is meant by a mixed melting-point determination?
"Mixed melting point determination" is a term used in chemistry. Organic substances have a fixed temperature at which they liquify. If a chemist wants to determine the nature of an unknown substance, he can determine it by these means. If the unknown substance does not melt at the usual temperature, it can be said to be impure. If the chemist has two unknown substances and wants to determine what they are, he may mix equal parts of each and start the liquification process. If the combination melts at the usual temperature, the chemist can say that both are the same. If the chemist wants to determine the nature of an unknown substance, he may mix a fixed amount of a known substance with a fixed amount of an unknown substance, it can be estimated, what the unknown substance is.
When might it be helpful to identify an unknown element?
It is helpful to identify an unknown element when you are exposed to a lot of it. This element could be very dangerous to you.
Why is it important to identify an unknown substance?
Because the substance could potentially be extremely toxic or harmful. You must never use an unknown substance in experiments without identifying it first, many tests can be undertaken to determine the cation and anion. These tests include the flame test, solubility tests, precipitate reaction tests and conductivity tests. These do vary depending on the unknown substance.
If an unknown substance CANNOT be broken down into simpler substances it is?
If an unknown substance cannot be broken down into simpler substances it is made of one kind of atom and an element.
How are constellations helpful to astronomers?
constellations aren't particularly helpful to scientists. they were helpful to people in ancient times for navigation and the answers to the unknown
When you are measuring the melting point of a mixture which consists of two unknown substances how can you find out what substances does the mixture consists of?
heat it
How can you determine charge for an unknown material?
One can determine the charge for an unknown material by using negligible friction. One will then be able to compare reactions between different charges that are brought near the unknown material.
Why are characteristic properties helpful in identifying an unknown substance?
