What is difference between thermal and photochemical reaction?
Photochemical reaction: a chemical reaction induced by electromagnetic radiations: ul- traviolet, visible, etc.) Thermal reaction: a chemical reaction induced by increasing the temperature (ex.: thermal dissociation, etc.)
What type of reaction occurs when copper carbonate is heated?
When copper carbonate is heated, a thermal decomposition reaction occurs. This reaction causes copper carbonate to break down into copper oxide and carbon dioxide gas, which is released as a byproduct.
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is a Exothermic b Reactant c Balanced d Endothermic?
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is endothermic.
What would the chemical reaction of a substance on heating?
This reaction is called thermal decomposition or thermal degradation; example: CaCO3 = CaO + CO2
What type of reaction occurs when an cooks in a pan?
This is a thermal degradation reaction.
How does the heat from a fire cause sodium bicarbonate to react?
When heat from a fire is applied to sodium bicarbonate, it causes a chemical reaction that releases carbon dioxide gas, water, and sodium carbonate. This reaction is known as thermal decomposition.
What are the dangers of thermal runaway reaction?
pain
What two substances causes an exothermic reaction?
Many substances can "cause" (or participate in) exothermic reactions. An exothermic reaction is a reaction that gives off thermal energy, as opposed to an endothermic reactionwhich requires the input of energy to occur. A classic example of an exothermic reaction is the burning of gasoline in an automobile engine. Gasoline is ignited to induce an exothermic combustion reaction with free oxygen in the air. The reaction causes the release of thermal energy which is converted to mechanical energy as the resulting gasses expand inside the engine's combustion chamber. Excess thermal energy is also released into the cylinder walls of the engine. So much so that your car has a coolant system just to absorb the excess thermal energy into a water-based coolant, and dissipate it from your radiator. Lots of heat energy being given off=exothermic reaction. And again, there are many different exothermic reactions involving many different substances.
WHAT CAUSES THERMAL BURNING?
Heat
How can you track thermal energy during a chemical reaction?
One way to track thermal energy during a chemical reaction is by using a device called a calorimeter. A calorimeter measures the heat released or absorbed during a reaction, allowing you to track the changes in thermal energy.
What type of reaction occurs when an egg cooks in a pan?
The cooking of an egg in a pan is a chemical reaction called denaturation. The heat causes the proteins in the egg to change shape, unfold, and form new bonds with each other, resulting in a solidified structure.
What is NaClO3 --NaCl O2?
This is a reaction of thermal decomposition.
