Yes.
Only if you include heat (magma, meteors, light bulbs), charged particles (lightning, aurora) and electroluminescence (LED) under "chemistry". None of these produce light by what we normally think of as a chemical reaction.
Chemical reactions that produce a rapid release of gas, heat, and light can lead to explosions. This can happen when highly reactive substances come in contact with each other, such as the reaction between an oxidizer and a fuel. Reactions involving energetic materials like nitroglycerin or TNT can also result in explosive outcomes.
Calvin Cycle
In a chemical reaction, changes in the arrangement of atoms and bonds occur as new substances are formed. Additionally, changes in energy levels, such as absorption or release of heat or light, are also common in chemical reactions. Moreover, changes in properties, such as color, odor, or state of matter, can often be observed as a result of a chemical reaction.
Most chemical reactions take place in the cytoplasm.
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.
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.
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.
Heat helps chemical reactions to take place. Light can also cause some chemical reactions to take place.
Luminous sources produce light through various processes, primarily through incandescence, fluorescence, and chemical reactions. Incandescence occurs when an object is heated to a high temperature, causing it to emit visible light, as seen in light bulbs. Fluorescence involves the absorption of energy by a substance, which is then re-emitted as light, commonly used in fluorescent lamps. Additionally, chemical reactions, such as combustion or bioluminescence in organisms, can also produce light without heat.
Light-dependent reactions occur in the thylakoid membranes of chloroplasts and require light to produce ATP and NADPH, which are used in the Calvin cycle to produce glucose. These reactions involve the conversion of light energy into chemical energy through the processes of photosystem I and photosystem II, as well as the electron transport chain. Oxygen is also produced as a byproduct of these reactions.

The primary function of the light-dependent reactions in photosynthesis is to convert light energy into chemical energy in the form of ATP and NADPH, which are used in the light-independent reactions (Calvin cycle) to produce glucose. These reactions occur in the thylakoid membranes of chloroplasts and involve the splitting of water molecules to release oxygen as a byproduct.
One example of a chemical reaction that produces heat and light is the combustion of hydrogen gas in air to form water. This reaction releases energy in the form of heat and light as the bonds between the atoms are broken and reformed.
Chlorophyll is the main pigment needed to carry out the chemical reactions of photosynthesis. It absorbs light energy from the sun and converts it into chemical energy that is used by the plant to produce glucose.

These are generally referred to as polymerization reactions. They may also be called condensation reactions sometimes.
