Is potassium in fireworks is very reactive a chemical or physical?
The reactivity of potassium in fireworks is a chemical property. This property describes how potassium interacts with other substances, such as oxygen, during combustion, resulting in a chemical reaction that produces light and sound. Physical properties, on the other hand, pertain to characteristics that do not change the substance's chemical identity, such as color or melting point. Therefore, potassium's reactivity is classified as a chemical property.
What chemical is used to make purple fireworks?
I would say Potassium is the closest chemical to a purple as it is a lilac/purplish colour.
What is the chemical reaction called where water is removed during the reaction?
This chemical reaction is called dehydration.
Potassium (K) combines with magnesium bromide (MgBr2) to form potassium bromide (KBr) and magnesium (Mg) during a single replacement reaction. Which of the following shows the balanced chemical equati?
The balanced chemical equation for the reaction where potassium (K) replaces magnesium (Mg) in magnesium bromide (MgBr2) to form potassium bromide (KBr) and magnesium (Mg) is: [ 2K + MgBr_2 \rightarrow 2KBr + Mg ] This equation indicates that two moles of potassium react with one mole of magnesium bromide to produce two moles of potassium bromide and one mole of magnesium.
What do scientist call a substance that forms during a chemical reaction?
Scientists call a substance that forms during a chemical reaction a product. This product is the result of the chemical reaction between the reactants.
Is Potassium chloride decomposes to potassium chloride and oxygen gas is a physical or chemical change?

What undergoes no chemical change during a chemical reaction?
A catalyst undergoes no chemical change during a chemical reaction.
What color flame is produced when potassium metal reacts with water?
When potassium metal reacts with water, it produces a lilac-colored flame. This flame color is a result of the energy released during the chemical reaction between potassium and water.
What chemical is used to make purple fireworks?
I would say Potassium is the closest chemical to a purple as it is a lilac/purplish colour.
Is endothermic a chemical reaction?
Yes. A chemical reaction which absorbs heat during the reaction. The opposite to exothermic which releases heat during the reaction.
What is the chemical reaction called where water is removed during the reaction?
This chemical reaction is called dehydration.
What is the scientific word for a gas given off during a chemical reaction?
A reaction that emmits heat is called an exothermic reaction .
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
What is new substance that is formed during a chemical reaction?
That would be the product of the chemical reaction.
What is the chemical that helps a chemical reaction without being consumed during a reaction?
ENzyme
What is chemical made during a chemical reaction?
the product
