When a log burns in a fire, what chemical reactions take place to produce heat and light?
When a log burns in a fire, the chemical reactions that take place involve the wood combining with oxygen in the air to produce heat and light. This process is known as combustion, where the wood undergoes a chemical reaction that releases energy in the form of heat and light.
What else can I help you with?
Does an explosion produce light?
Not necessarily. Many of the explosions we are familiar with involve high-temperature chemical reactions, which do release light. Explosions at lower temperature, such as steam explosions, do not produce light.
What happens when something burns and why does it produce heat and light?
When something burns, it undergoes a chemical reaction called combustion. During combustion, the material combines with oxygen in the air to produce heat and light. The heat is generated because the chemical bonds in the material are broken, releasing energy. The light is produced as a result of the high temperatures reached during the combustion process, causing the material to emit photons.
What is energy of a candle?
The energy of a candle comes from the chemical reactions that occur when the candle burns. This process releases heat and light energy in the form of a flame. The energy produced by a candle can be used for lighting or heating purposes.
Is firework a light source?
Yes, it is. Fireworks gives off its own light.
What happens when wood burns and why does it produce heat and light?
When wood burns, it undergoes a chemical reaction called combustion. During combustion, the wood reacts with oxygen in the air to produce heat and light. This process releases energy in the form of heat and light because the bonds holding the molecules in the wood together are broken, releasing stored energy. The heat and light produced during combustion are the result of this energy being released.
Do most of the chemical reactions that give off light also produce heat?
Yes, most chemical reactions that give off light also produce heat. This phenomenon is known as chemiluminescence, where the energy released during the reaction is emitted as both light and heat. However, not all reactions that produce light necessarily produce heat, as some reactions can be endothermic and absorb heat instead.
Do a chemical reaction produce heat and light?
Chemical reactions can produce heat and energy but not all chemical reactions produce them. Exothermic reactions produce heat and energy (possibly in the form of photons/light), while endothermic reaction absorb them.
Why does the sun produce light of that wavelength?
Because that's what the chemical reactions going in in the sun does.
Is the absorption of light and chemicals produce a chemical reaction?
Yes, it is possible; photochemistry study the chemical reactions caused by visible and ultraviolet light.
What are light independent and dependent reactions?
Light dependent reactions are reactions the capture light energy and convert it into chemical energy(ATP). It occur in the chloroplast of plant cells Light independent reactions are reactions capture energy and use it to produce food . It does not need sunlight
Do water and vinegar produce light?
No. Mixing the two will not produce light.
Breaking a light stick chemical change?
When you break a light stick, it is a physical change, not a chemical change. The breaking of the light stick only changes its physical state but does not alter its chemical composition. This is because the chemical reactions that produce light in a light stick have already occurred when the stick was activated, and breaking it does not initiate any new chemical reactions.
What reactions convert light energy to chemical energy?
The light dependent reactions take in the light energy and convert that to chemical energy, but it is in the Calvin cycle (light independent reactions) where the chemical energy is stored in a complex sugar.
Does an explosion produce light?
Not necessarily. Many of the explosions we are familiar with involve high-temperature chemical reactions, which do release light. Explosions at lower temperature, such as steam explosions, do not produce light.
Does oxygen produce light?
Essentially oxygen does not produce light ... light itself is an energy, and cannot be created only changed
Which of the following statements about the light reactions of photosynthesis are true?
The light reactions occur in the thylakoid membrane of the chloroplast. The primary goal of the light reactions is to convert light energy into chemical energy in the form of ATP and NADPH. Water is split during the light reactions to provide electrons for the photosystems. The light reactions produce oxygen as a byproduct.
Can light bring about chemical reactions and can chemical reaction produce light?
Light can indeed cause chemical reactions. A very good example of this happens constantly above our heads. The light from the sun causes the formation of oxygen radicals in the atmosphere by disocciation. The formula for this is: O2 + hv --> 2O. , where h is planck's constant and v is the frequency of the light. The "." on the oxygen atoms formed represent a single unpaired electron which causes them to become very reactive (they will react with almost anything). They react with other O2 molecules to form O3, better known as ozone. This is how the ozone layer is formed. Reactions can indeed produce light. Ever used a glowstick? You break a capsule inside and then shake the stick to cause a chemical reaction which gives off light. This also explains why glowsticks stop glowing. The reaction has finished. Unfortunately I do not know the reaction for this process or indeed which chemicals are involved.
