What else can I help you with?
Is thermal energy created or used?
neither, Law of conservation of energy in a nutshell: energy cant be created or destroyed. Energy can be converted nothing else. IE: when you burn a candle you are CONVERTING the chemical energy stored in the candle into thermal energy.
Is cracking hydrocarbon molecules an endothermic or exothermic reaction?
Cracking hydrocarbon molecules is an endothermic reaction. This process requires energy input to break the chemical bonds in larger hydrocarbon molecules, resulting in smaller molecules, such as alkanes and alkenes. The energy absorbed during cracking exceeds the energy released from the formation of the new bonds in the products, making it endothermic.
What type of energy dose a light stick have?
Assuming that you are referring to non-electric light sticks, it is chemical energy. The reaction is started by mechanical energy (cracking the stick). The chemical nature of glow sticks is also evident in the fact that they die down eventually after the reactants are used up.
Is a firework cracking a physical or chemical change?
It is a chemical change as it releases gases into the air.
What are the two necessary conditions for cracking to take place?
The two necessary conditions for cracking to take place are high temperature and presence of a catalyst. High temperature allows for the breaking of chemical bonds in the hydrocarbon molecules, while the catalyst accelerates the cracking reaction by providing an alternative pathway with lower activation energy.
Is cracking of petroluem fraction a physical or chemical change?
Cracking of petroleum fractions is a chemical change. It involves breaking down larger hydrocarbon molecules into smaller, more valuable ones through the use of heat and catalysts. This process alters the chemical composition of the molecules, resulting in the formation of different products.
How are petrochemicals broken down?
This chemical process is called cracking.
Is cracking an egg an irreversible physical change?
Physical
Photosynthesis converts solar energy into what type of energy?
chemical energy
Cracking a raw egg endothermic or exothermic?
Endothermic because the egg is absorbing the heat.
Is cracking eggs a chemial change?
Cracking an egg is a physical change, not a chemical change.
What does chemical energy?
chemical energy is energy stored in chemical bonds.
