chemical reaction
This chemical reaction is known as combustion.
Synthesis
Putting a chemical equation into words helps to describe the reactants, products, and the chemical reaction that is occurring. It allows for easier communication of the reaction process and helps in understanding the stoichiometry involved. Additionally, writing chemical equations in words helps to identify the type of reaction taking place.
No. The ice melting is a physical change.
Yes, putting metal in acid is a chemical change because a new substance is formed as a result of the reaction between the metal and the acid. This reaction typically involves the metal losing electrons to the acid, resulting in the formation of new chemical compounds.
Magnesium is highly reactive to water because of the atom's electron arrangement. The products of the reaction are, heat, light, and gas, which are all indicators that they had undergone a chemical reaction.
Yes, indeed. Epoxy resin cures by chemical reaction. Any chemical reaction is speeded up when you heat it, but when you cool it in the fridge, the reaction slows way down!
Mixing is a physical process.
it's not. tell whoever told you that to go back to pre-school.
Putting a penny in lemon juice would cause a chemical change because the lemon juice reacts with the copper in the penny to create copper oxide, which changes the chemical composition of the penny.
They form a compound. Two materials combining chemically creates a reaction. It joins them at an atomic level creating a whole new substance. Ex:It is not like putting bread on butter. It is more like putting bleach into ammonia.
