CuSO3 + heat = CuO + SO2 so Copper oxide and sulfur dioxide are produced.
CuCO3 +heat------->> CuO +CO2
CuCO3(s)-----heat---->CuO(s)+CO2(g) black
Burning coal is a chemical change. Anytime heat is released (as such in fire) it will be a chemical property change.
The sidewalk being warmed by the heat of the sun is a physical change not a chemical change.
chemical change because there is release of heat, light and energy.
Yes, it is an exothermic chemical reaction.
Fire is Combustion, in which your reactant is reacted with oxygen and heat to form carbon dioxide and water, so you turn your reactant into a product this is a chemical change.
Temperature change, more accurately, a change in heat, is not a chemical change because it does not happen on a chemical level. Heat is the product of varying levels energy, not physically tangible particles. The higher the energy the higher the heat. To clear up any further confusion, a lot of people think heat is a chemical process, but it's not. Most people that think this, do so because the first way most of us imagine this change is through exothermic (reactions that create heat) reactions which are chemical processes like explosions.
Neither. Body heat is a result of chemical changes, but it's not itself a chemical change.
Metamorphism
Its a chemical change hottie
Chemical
Change in colour, energy(heat, light sound) is produced. or in the case of heat it can also be absorbed. a precipitate, or new product is formed such as gas.
I would think it to be a Physical Change. Not chemical.
CuCO3(s)-----heat---->CuO(s)+CO2(g) black
This is an exothermic reaction.
It is a chemical change because the heat and whatnot alter the chemical makeup.
Which of the following variables are used to calculate the sensible heat load of a product? Group of answer choices Respiration heat, specific heat, and temperature change. Latent heat, product weight, and temperature change. Latent heat, product weight, and respiration heat. Product weight, specific heat, and temperature change.
