Which kind of water has undergone purification?
Purified water has undergone a process to remove impurities and contaminants, such as chemicals, bacteria, and minerals. This process typically involves filtration, distillation, or reverse osmosis to ensure the water meets certain purity standards.
When a substance changes from one physical form to another we say the substance has undergone a(n) blank?
When a substance changes from one physical form to another, we say the substance has undergone a phase transition. This can occur through processes such as melting, freezing, evaporation, condensation, or sublimation. Each of these transitions involves changes in energy and molecular arrangement, but the chemical composition of the substance remains the same.
When a substance changes from one physical form to another you say the substance has had a what?
When a substance changes from one physical form to another, you say the substance has had a phase change or undergone a phase transition.
What is the correct meaning of alcohol?
An impalpable powder., The fluid essence or pure spirit obtained by distillation., Pure spirit of wine; pure or highly rectified spirit (called also ethyl alcohol); the spirituous or intoxicating element of fermented or distilled liquors, or more loosely a liquid containing it in considerable quantity. It is extracted by simple distillation from various vegetable juices and infusions of a saccharine nature, which have undergone vinous fermentation., A class of compounds analogous to vinic alcohol in constitution. Chemically speaking, they are hydroxides of certain organic radicals; as, the radical ethyl forms common or ethyl alcohol (C2H5.OH); methyl forms methyl alcohol (CH3.OH) or wood spirit; amyl forms amyl alcohol (C5H11.OH) or fusel oil, etc.
How can you see if a substance has undergone a chemical change?
You can determine if a substance has undergone a chemical change by observing specific indicators, such as the production of gas (bubbles), a change in color, the formation of a precipitate, or a change in temperature (exothermic or endothermic reactions). Additionally, if the original substance cannot be easily recovered or transformed back into its initial state, it is likely that a chemical change has occurred.
What is distilliation?
Distilled water has undergone a process called Distillation in order to remove impurities. The method involves boiling water and collecting the steam which is then condensed, while any impurities are left as residue.
What is the difference between respiration to fermentation?
Respiration is the process where cells break down glucose in the presence of oxygen to produce energy, while fermentation is the process where cells break down glucose in the absence of oxygen to produce energy. Respiration produces more energy (ATP) compared to fermentation and is more efficient. Fermentation produces byproducts such as lactic acid or ethanol, while respiration produces carbon dioxide and water.
What is distillied water?
Distilled water has undergone a process called Distillation in order to remove impurities. The method involves boiling water and collecting the steam which is then condensed, while any impurities are left as residue.
When a substance change from one physical form to another you say the substance has had an?
When a substance changes from one physical form to another, it has undergone a phase change. This can include processes like melting, freezing, vaporization, condensation, and sublimation.
Is coal a organic substance?
Yes, coal is considered an organic substance because it is derived from the remains of plants and organic matter that have undergone geological processes over time, leading to its formation as a fossil fuel.
Is fermentation an oxidation or a reduction process?
Fermentation is not considered as an oxydation reaction. ------------------------------------------------------------------ It may not usually be considered as such, but the oxidation state of C in sugar is zero, and the oxidation state of C in ethanol is -2. Any change in oxidation state can be treated as a redox process. Loss of electrons (or an increase of oxidation state) is oxidation, gain of electrons (or a decrease of oxidation state) is reduction. The carbon that ends up in the ethanol has decreased its oxidation state from 0 to -2 so those atoms have undergone reduction. Reduction cannot exist without a subsequent oxidation, so something else has undergone oxidation. The fermentation process also makes carbon dioxide. The C in those molecules has an oxidation state of +4, so those atoms of carbon have been oxidized. So the answer is --- both.
