What will happen to the powdered sulfur when heat was applied?
When heat is applied to powdered sulfur, it will melt and eventually vaporize. This process is called sublimation, where a solid substance bypasses the liquid phase and turns directly into a gas.
Why the mixture of the metal fillings and sulfur becomes chemical change when heat was applied?
When heat is applied to the mixture of metal fillings and sulfur, a chemical reaction occurs. The heat provides the energy necessary for the atoms of the metal and sulfur to rearrange and form new chemical bonds, resulting in the formation of a new substance with different properties than the original components. This process is called a chemical change, where the original substances react to form different compounds.
Is mixing iron filing and sulfur is a physical change?
It's just physical, unless you heat the mixture. The simple combination of iron and sulfur is a physical mixture: It can be separated with a magnet, and the iron and sulfur are still themselves. The situation changes if you heat the mixture hot enough to start a reaction between the sulfur and iron. If you do so, assuming the ingredients are in the right proportions, you'll have iron sulfide (a compound) and no free iron or sulfur will remain. In that case, you have a chemical reaction.
How do you separate mixture of sulfur and charcoal?
You can separate a mixture of sulfur and charcoal by using a method called sublimation. Heat the mixture in a test tube or flask, where the sulfur will sublimate (turn into gas) and leave the charcoal behind. The sulfur gas can then be collected and condensed back into solid form.
Potassium chloride flammable when mixed with sulfur?
Potassium chloride itself is not flammable. However, when mixed with sulfur, the mixture can become flammable as sulfur can act as a fuel source. This mixture can be explosive when exposed to high heat or flame.

How do you get powdered charcoal from a mixture of copper oxide and powdered charcoal?
To obtain powdered charcoal from a mixture of copper oxide and powdered charcoal, you can use a reduction reaction. Heat the mixture in a furnace or with a suitable heat source, as copper oxide will react with the charcoal (carbon) to form copper and carbon dioxide. The copper will be produced as a metal, leaving behind the powdered charcoal. After cooling, you can separate the unreacted charcoal from the copper.

Is heating up sulfur a chemical change?
It is not a chemical change, unless you heat it sufficiently to make it catch fire.
How do you separate the mixture of sulfur from charcoal?
One way to separate sulfur from charcoal is through sublimation. Heat the mixture in a container where sulfur can vaporize and then condense on a cooler surface, separate from the charcoal. This method takes advantage of the difference in sublimation temperatures between sulfur and charcoal.
What is the specific heat of mixture and how does it affect the overall temperature change in a system?
The specific heat of a mixture is the amount of heat needed to raise the temperature of the mixture by 1 degree Celsius. It affects the overall temperature change in a system because substances with higher specific heat require more heat to raise their temperature, while substances with lower specific heat require less heat. This means that the specific heat of a mixture determines how much heat is needed to change its temperature, impacting the overall temperature change in the system.
What is the heat capacity of a mixture and how does it affect the overall thermal properties of the system?
The heat capacity of a mixture is the amount of heat needed to raise the temperature of the mixture by a certain amount. It affects the overall thermal properties of the system by determining how much heat energy is required to change the temperature of the mixture. A higher heat capacity means the mixture can absorb more heat without a significant temperature change, while a lower heat capacity means the temperature will change more easily with the addition or removal of heat.
Is heating sulfur a chemical change?
It is not a chemical change, unless you heat it sufficiently to make it catch fire.
Describe how to separate a mixture of iron and sulfur?
Use a magnet to separate the iron particles from the mixture, as iron is magnetic and sulfur is not. Heat the mixture to a high temperature to burn off the sulfur, leaving behind the iron. Alternatively, dissolve the mixture in water to separate the sulfur, which will dissolve, leaving the iron behind.
