What is the black material on a candle wick?
The black material on a candle wick is typically carbon residue. This residue forms as the wick burns and is a byproduct of the combustion process. It is normal for candles to produce some amount of soot as they burn.
When magnesium burns in air what do you see happen?
When magnesium burns in air, it produces a brilliant white light and intense heat. The magnesium metal combines with oxygen in the air to form magnesium oxide, which is a white powdery substance that is often seen as a residue during the burning process.
What is the property of sulphuric acid when added to sugar that converts it to a black residue carbon?
Sulfuric acid is a strong dehydrating agent, meaning it removes water molecules from the sugar (sucrose) through a chemical reaction. This reaction breaks down the sugar molecules, leading to the formation of elemental carbon which appears as a black residue.
Magnesium sulfate and vinegar reaction?
Magnesium reacts with hydrochloric acid according to the equation: Mg (s) + 2 HCl (aq) --> MgCl2 (aq) + H2 (g). So, magnesium chloride and hydrogen gas is the result of mixing magnesium and hydrochloric acid.
What catalysts to use for reaction between magnesium and hydrochloric acid?
A common catalyst used for the reaction between magnesium and hydrochloric acid is platinum metal in the form of platinum black. This catalyst helps to increase the rate of the reaction by providing a surface for the reactants to interact. Alternatively, no catalyst is typically needed for this reaction as it occurs spontaneously at room temperature.
Why is incomplete combustion messy?
Incomplete combustion occurs when there is insufficient oxygen present to fully burn the fuel. This leads to the production of soot, carbon monoxide, and other harmful byproducts. These byproducts can accumulate and create a messy residue, such as black carbon deposits or soot, which can stain surfaces.
What element in organic compound causes the formation of black residue?
Incomplete combustion of carbon-containing compounds, such as hydrocarbons, can lead to the formation of black residue due to the production of elemental carbon (soot). This soot is responsible for the black color seen in the residue.
What is the black solid that is formed in the combustion of hexane?
Coke, most likely. Coke is the carbonaceous residue left over from the thermal "cracking" of hydrocarbons (the term is also used to describe the residue left over from coal combustion).
What is the black material on a candle wick?
The black material on a candle wick is typically carbon residue. This residue forms as the wick burns and is a byproduct of the combustion process. It is normal for candles to produce some amount of soot as they burn.
Why would water turn black when rinsing a glass coffee pot with just the coffee residue left in it?
The glass could have traces of magnesium in it which when combined with hard water would create magnesium-oxide. This chemical change would turn the water black.

What happens to a match to make it go black?
a chemical reaction (combustion reaction) the heat from the friction of the sand paper lights the match. the flame burns the chemicals and the oxygen in the air. whatever isn't burnt is left on the matchstick. this is mainly carbon (i think) whick is the black stuuf =]
When magnesium reacts with CO2 a black solid is produced name the solid?
The reaction is: 2 Mg + CO2 = 2 MgO + C The black solid is this carbon.
Magnesium sulfate and vinegar reaction?
Magnesium reacts with hydrochloric acid according to the equation: Mg (s) + 2 HCl (aq) --> MgCl2 (aq) + H2 (g). So, magnesium chloride and hydrogen gas is the result of mixing magnesium and hydrochloric acid.
What is observed when heating Fe and S?
When heating iron (Fe) and sulfur (S) together, a chemical reaction occurs to form iron sulfide (FeS). This reaction is exothermic and produces a black solid product. The iron sulfide formed can be observed as a black solid residue after the reaction is completed.
