Is tarnishing a chemical reaction?
Tarnish is a product of a chemical reaction between a metal and a nonmetal compound, especially oxygen and sulfur dioxide.
It is usually a metal oxide, the product of oxidation.
Sometimes it is a metal sulfide.
The metal oxide sometimes reacts with water to make the hydroxide; and carbon dioxide to make the carbonate..
How does photosynthesis work simple?
Plants take in water from the soil and carbon dioxide from the air. Photosynthesis starts when chlorophyll absorbs energy from sunlight. Green plants use this light energy to change water and carbon dioxide into oxygen and nutrients called sugars. The plants use some of the sugars and store the rest.
What are 10 examples of physical changes?
Examples of Physical ChangesCrushing a can.Melting an ice cube.Boiling water.Mixing sand and water.Breaking a glass.Dissolving sugar and water.Shredding paper.Chopping wood.More items…•
What are 3 examples of a chemical reaction?
Examples of Simple Chemical Reactionshydrogen + oxygen —> water.iron + oxygen —> rust.potassium and chlorine gas —> chloride.lime + carbon dioxide —> calcium carbonate (used to strengthen masonry)water + carbon dioxide + light —> glucose and oxygen (photosynthesis)More items…
What is photosynthesis very short answer?
Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.
Is protein a chemical reaction?
Protein Structure It is a reaction in which two molecules combine to form a single molecule with a release of water (see figure below). When two amino acids combine in a condensation reaction, a covalent bond forms between the amine nitrogen of one amino acid and the carboxyl carbon of the second amino acid.
What is photosynthesis simple answer?
Photosynthesis takes in the carbon dioxide produced by all breathing organisms and reintroduces oxygen into the atmosphere. (Image: © KPG_Payless | Shutterstock) Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight and turn it into chemical energy.
Why is photosynthesis a chemical reaction?
Photosynthesis requires energy, making it an endothermic reaction. Light, generally sunlight, is the source of this energy. The process converts the sun’s electromagnetic energy into chemical energy, which is then stored in chemical bonds in the plant. … This energy is released when fuels are burned.
What are the chemical reactions in photosynthesis?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
Why is photosynthesis an example of an endothermic reaction?
plants do not create oxygen it is a by-product of Photosynthesis. Photosynthesis is an endothermic reaction because sunlight is being absorbed during the reaction and the definition suggests that in a reaction if heat is being absorbed it is termed as an endothermic reaction.
Does Heat contain chemicals or is it a chemical reaction?
Application of heat to certain substances causes only physical changes in which no new substance or substances are formed. Application of heat to some substances causes chemical changes, or chemical reactions, in which one or more new substances are formed, with different properties from the original.
Where do the chemical reactions of photosynthesis occur?
the chloroplastPhotosynthesis occurs in the chloroplast of the plant cell. Carbon dioxide, water, and the sun’s energy are necessary for the chemical reactions of photosynthesis. The products of photosynthesis are glucose and oxygen.
What is an example of a color change in a chemical reaction?
When copper reacts with the elements (oxygen, water and carbon dioxide), it turns from its element color of reddish-brown to green. This chemical reaction is hydrated copper carbonate, and a famous example of it is the Statue of Liberty.
Is photosynthesis an example of chemical reaction?
Photosynthesis in plants is also an example of a chemical reaction. In this case, sunlight is changed into food for the plant.
Is a rainbow a chemical reaction?
A rainbow is not a chemical reaction, but is an optical illusion due to sunlight passing through water droplets in the atmosphere.
What are 4 examples of chemical changes?
Examples of Chemical ChangesBurning wood.Souring milk.Mixing acid and base.Digesting food.Cooking an egg.Heating sugar to form caramel.Baking a cake.Rusting of iron.
What happens during photosynthesis step by step?
It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and (4) conversion of CO2 into carbohydrates (carbon fixation).
Is photosynthesis the most important chemical reaction?
Photosynthesis is the most important chemical reaction in the biosphere, as it is the prerequisite for all higher life on earth.
