What is the colour of copper sulphate crystals before and after heating?
Copper Sulphate crystals before heating r blue....but after heating I dunno , may be u should try and ask your Sci.Miss/Sir I'll get back when I get the other answer .
What is the process of molten material?
The process of molten material involves heating a solid substance to its melting point, causing it to turn into a liquid state. This can occur through various methods such as heating in a furnace or using a torch. Once in a molten state, the material can be manipulated or molded into different shapes before it solidifies again upon cooling.
Is heating copper sulfate pentahydrate a chemical reaction?
No, it is not a chemical reaction. The added heat only drives the water molecules out of the crystal structure. No bonds are made or broken. Actually, it is a chemical change, because there are bonds between the water and CuSO4. by heating, these bonds are broken, there is a color change not coming from the reactant.
How can one determine the residence time of a substance in a system?
The residence time of a substance in a system can be determined by dividing the total amount of the substance in the system by the rate at which the substance is entering or leaving the system. This calculation gives an estimate of how long the substance stays in the system before being removed or depleted.
How do you calculate the mean residence time in a system?
To calculate the mean residence time in a system, you divide the total amount of time a substance spends in the system by the total amount of that substance in the system. This gives you an average time that the substance remains in the system before leaving.
What are the physical appearance of NaCl before heating?
Sodium chloride at room temperature is a crystalline transparent substance.
What happens to a substance that break apart before it can melt?
This is a thermal decomposition reaction: new compounds are obtained by heating.
How long from the from the start of the experiment was the substance heated before all of the substance turned into a liquid?
It is impossible to tell how long from the start of the experiment it was before all of the substance turned into a liquid without more information about the experiment. Perform the experiment again and use a timer to determine the length of time required to turn the substance into a liquid through heating.
When heating frozen pizza should you put toppings before heating or after?
before
Which substance shrinks on heating?
Most substances expand when heated, but water is an exception. Water contracts when heated from 0°C to 4°C before expanding as it heats up further.
A substance breaks down into its component elements when it is heated If 61.8 grams of the substance is present before it is heated what is the combined mass of the component elements after heating?
68.0 grams due to the law of conservation of mass which states that mass can not be lost but only converted.

What are the similarities of limestone before heating and after heating?
your scene of touch can help you tell how hot or cold an object is.
What steps can you take to determine the melting point of a substance that sublimes before it melts?
In such cases the melting point determination must be performed in a sealed capillary tube to avoid loss of sample. This can be achieved by heating the open end of the capillary tube, and with tweezers forcing it shut.
What is the reason for heating the tubes before and after each transfer?
You are not so much as heating tubes but preventing unwanted microbes from "sneaking" into the culture. You are sterilizing the mouth of the tube before and after.
Why should you air-dry a specimen before heating in laboratory experiments?
You should air-dry a specimen before heating it in the labratory in order to get rid of any impurities. Also, it helps you record the best and most accurate figure while heating.
