Yes is it a chemical change as the process is irreversible. Also its properties are being changed and it looks different physically which always means a chemical change has occurred or will occur if certain substances are put together.
Chemical change. Burning anything will create a chemical change. Burning involves taking the object/substance being burnt + oxygen to produce water and carbon dioxide.
The balanced chemical equation for limestone (calcium carbonate, CaCO3) being heated strongly in air is: CaCO3(s) → CaO(s) + CO2(g)
Yes it is!:Pwhen a candle is lighted the solid wax changes into liquid wax,then it turns into vapour to produce flame.new substances like Co2 and H2O are formed alongwith the evoulation of light and heat.
Physical change involves a change in the form or state of matter without changing its chemical composition, such as melting ice to water. Chemical change involves a change in the chemical composition of a substance, resulting in new products being formed, such as burning wood to produce ash and smoke. Observing changes in properties, such as color, odor, or temperature, can help distinguish between physical and chemical changes.
physical. the water being added simply soaks through the coffee, so there's no chemical change.
yes
The production of chlorine gas when calcium chloride is heated to decomposition is a chemical change. This is because a new substance (chlorine gas) with different chemical properties is formed as a result of a chemical reaction taking place between the calcium chloride and heat.
When sugar caramelizes on being heated above its melting point, it undergoes a chemical change. This is because the heat causes the sugar molecules to break down and rearrange into new compounds, resulting in the formation of caramel.
Chemical change. Burning anything will create a chemical change. Burning involves taking the object/substance being burnt + oxygen to produce water and carbon dioxide.
Yes, heating mercury to produce mercury vapor is a physical change because no new substances are formed. The change is reversible, and the mercury can return to its original state once cooled back down.
The change of water into steam is a physical change. This is because the molecules of water are simply being rearranged into a different state (liquid to gas) without undergoing any chemical reactions.
When a mixture is heated, the individual components may react differently based on their physical and chemical properties. Some components may evaporate, others may change state, and some may undergo chemical reactions. The outcome would depend on the specific mixture being heated.
Turning a brownie mix into brownies is a chemical change. When the ingredients are heated in the over, numerous chemical reactions take place. Because new substances are created in the process, the process is a chemical change.
no. what would give you that idea?
Yes, this observation of a black solid turning into a purple gas when heated suggests a chemical change. The change in color and state indicates that new substances are being formed through chemical reactions taking place in the solid material.
chemical change
Heating water to make it hot is a physical change, as the water's chemical composition remains the same. The change in temperature simply affects the kinetic energy of the water molecules, causing them to move faster and appear hot.
