The substances in paraffin do not chage when a candle burns?
When a candle burns, the paraffin wax reacts with oxygen to form carbon dioxide and water vapor. The carbon atoms in the paraffin combine with oxygen from the air to produce heat, light, carbon dioxide, and water. This chemical reaction is why the substances in paraffin change when a candle burns.
How are new substances made in a chemical reaction?
These substances are called products (or final products).
What are the reactant the bit you start with?
The reactants are the starting substances in a chemical reaction that undergo change to form products. In a typical reaction, these substances are combined, and their bonds are broken and reformed to create new compounds. Identifying reactants is crucial for understanding the reaction's mechanism and predicting the products formed. For example, in the combustion of methane, the reactants are methane (CH₄) and oxygen (O₂).
Do new substances made in a chemical reaction have new properties?
Yes, new substances formed in a chemical reaction often have different properties than the original substances. This is because the arrangement of atoms in the molecules of the new substances is different, leading to changes in their physical and chemical properties.
Is burning an irreversible change that produces no new substances?
Burning is an irreversible change that produces new substances. When a substance burns, it undergoes a chemical reaction with oxygen to form new compounds like carbon dioxide, water vapor, and ash. This transformation is not easily reversible, as the original substances are no longer present in their original form.
What new substances are made when a fuel burns?
Carbon dioxide and water, assuming the fuel is a hydrocarbon.
Is Natural gas burns a chemical or physical property?
The burning of natural gas is a chemical property because it involves a chemical reaction. When natural gas (methane) reacts with oxygen in the air, it produces carbon dioxide, water, and heat energy. This is a chemical change as new substances are formed.

When a candle burns, the paraffin wax reacts with oxygen to form carbon dioxide and water vapor. The carbon atoms in the paraffin combine with oxygen from the air to produce heat, light, carbon dioxide, and water. This chemical reaction is why the substances in paraffin change when a candle burns.

What are the gases of New York?
methane and others but mostly methane XD methane and others but mostly methane XD
Is burning methane a physical or chemical change?
Burning methane is a chemical change because it involves a chemical reaction between methane and oxygen to produce carbon dioxide and water. This reaction results in the formation of new substances with different properties from the original methane gas.
Do new substances made in a chemical reaction have new properties?
Yes, new substances formed in a chemical reaction often have different properties than the original substances. This is because the arrangement of atoms in the molecules of the new substances is different, leading to changes in their physical and chemical properties.
Is burning gas a chemical reaction?
Because a chemical change results in the formation of 1 or more new substances and a new compound is created, methane burns with a smokey flame that forms carbon dioxide and water, which makes it a chemical reaction.
Is burning an irreversible change that produces no new substances?
Burning is an irreversible change that produces new substances. When a substance burns, it undergoes a chemical reaction with oxygen to form new compounds like carbon dioxide, water vapor, and ash. This transformation is not easily reversible, as the original substances are no longer present in their original form.
Was a dug a dug made bye Robert Burns?
Yes, "Auld Lang Syne" is a poem written by Robert Burns. It is traditionally sung to celebrate the start of the New Year.
What are the reactants and the products of the forward Left to right reaction?
Reactants- The substances used up in a reaction. Products- The new substances made.
Where was Ursula Burns born?
Ursula Burns was born in New York, New York in the United States.
