Why is decolorizing charcoal added to the hydrogenation reaction mixture in the third experiment?
Decolorizing charcoal is added to the hydrogenation reaction mixture to adsorb impurities and colored byproducts that may form during the reaction. This helps to purify the product by removing unwanted substances, ensuring a cleaner final product. Additionally, the use of charcoal can enhance the overall efficiency of the reaction by improving the reaction conditions and preventing catalyst poisoning.
The burning of charcoal is a spontaneous process yet heat must first be applied to start a charcoal why?
Burning charcoal is spontaneous, but not at room temperature. To start the combustion energy must be added (in the form of heat). Once the temperature of the charcoal reaches a certain temperature it reacts exothermically and releases heat. This heat of reaction is sufficient to locally heat more charcoal so that it burns continuously.
What method is used to separate charcoal powder and iron fillings?
Well, honey, to separate charcoal powder and iron fillings, you can use a little technique called magnetic separation. Just grab a magnet, wave it over the mixture, and watch as those pesky iron fillings cling to the magnet while the charcoal powder minds its own business. Easy peasy lemon squeezy!
The burning of charcoal is a spontaneous processyet heat must first be applied to start a charcoal why?
The combustion of charcoal is an exothermic reaction: once the reaction starts, it releases heat, making it self-sustaining. However, initially, an external source of heat is required to overcome the activation energy barrier and initiate the reaction. Once started, the reaction releases enough heat to sustain itself.
What does activated charcoal do in hand warmers?
Activated charcoal in hand warmers serves as a heat source by undergoing an exothermic reaction with iron powder and salt when exposed to air. This reaction generates heat that warms up the hand warmer.
Is there a reaction when charcoal and lead mix together?
No.

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.
How do you get the reactants of charcoal oxygen?
Charcoal primarily consists of carbon. To get the reactants of charcoal and oxygen, you simply need to combine charcoal (carbon) with oxygen gas. The balanced chemical equation for this reaction is: C + O2 -> CO2.

Is gunpowder magnetic?
My son who is in 3rd grade is studying magnetite and he has been told that magnetite can be used as a gunpowder and of course that is magnetic.
Is magnetic material a catalyst in a reaction?
No, not normally.
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 charcoal burning on the grill a chemical or physical change?
Charcoal burning on the grill is a chemical change because the charcoal undergoes a chemical reaction with oxygen to produce heat and new chemical compounds like carbon dioxide and water vapor.
