Do the ashes from charcoal have a greater mass than when there whole?
No, the ashes from charcoal have a lesser mass than the original charcoal. When charcoal burns, it undergoes a chemical reaction that releases gases and leaves behind mostly carbon in the form of ashes.
What is reconstituted water?
Reconstituted water is water that has been restored to its original state by adding water back to a concentrated form. This process is commonly used in food production when dehydrated ingredients need to be mixed with water to bring them back to their original consistency.
Why are the burning of charcoal in a grill is a chemical change?
The burning of charcoal in a grill is a chemical change because it involves a combustion reaction where charcoal (carbon) reacts with oxygen in the air to produce carbon dioxide, heat, and light. This process transforms the charcoal into different substances, and it cannot be reversed; once burned, the charcoal cannot be restored to its original form. The release of energy in the form of heat and light further indicates that a chemical transformation has occurred.
Is charcoal explosive?
Charcoal itself is not explosive; it is primarily a solid fuel that burns slowly and steadily. However, when finely powdered, charcoal can pose a dust explosion hazard if dispersed in air and exposed to an ignition source. In its typical form, charcoal is safe to handle and burn but should be managed carefully when in dust form to avoid potential risks.
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.

What does charcoal and oxygen form?
Charcoal and oxygen combine to form carbon dioxide. This reaction occurs when charcoal burns in the presence of oxygen, releasing energy in the form of heat and light.
What changes shape but can change back to its original form?
A rubber band can be stretched to change shape but can go back to its original form when released.
How do crystals form on charcoal?
Crystals can form on charcoal through a process called sublimation. This occurs when a solid substance transitions directly into a gas state without passing through the liquid phase. By heating the crystalline substance on charcoal, it creates vapors that then cool and solidify back into crystals on the surface of the charcoal.
Charcoal is a form of what?
carbon
What can you change back from a physical change?
A physical can be changed back to it's original form. For example, if you freeze water, it turns into ice. However, if that ice melts, it turns back into it's original form: water.
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.
Why is crystallizing a chemical change?
because u cant change it back form its original form
Does charcoal form a covalent bond?
Its kind of a trick question. Charcoal is not a chemical compound or a pure form of carbon. The main constituent is graphite, which is covalently bonded, with delocalised electrons in pi bonds that are easily excited by light, hence absorbing it, which makes it appear black
What is the most natural form of charcoal?
Trees.
