What does Delta S 0 mean answers com?
The answer is 0 (zero) Sides on a Circle.
Is photosynthesis easily reversible?
Hence , formation of glucose is a chemical change , so the process of photosynthesis can not be reversed. So , it’s Irreversible.
Why is photosynthesis not reversible?
Photosynthesis is irreversible because the enzymes are highly specific for their substrate (reactants). Many enzymes are unable to facilitate the reverse reaction.
How do you know if two compounds will react?
One substance will react with another if the reaction is “spontaneous”. Dr. Gibbs gave us a super cool equation that lets us predict if a reaction will happen. If the energy of a reaction is lower as a product than a reactant, the reaction will happen.
Which of the following do photosynthesis and cellular respiration have in common?
Both processes involve energy conversions. Both processes use and produce ATP. Both processes take place in the mitochondrion of a cell. Both processes use an electron transport chain.
How do you know if a reaction is single or double replacement?
A single-replacement reaction replaces one element for another in a compound. The periodic table or an activity series can help predict whether single-replacement reactions occur. A double-replacement reaction exchanges the cations (or the anions) of two ionic compounds.
What are 3 differences between photosynthesis and respiration?
The principal difference, however, between photosynthesis and respiration is that photosynthesis utilizes carbon dioxide and water in the presence of light to produce glucose and oxygen, whereas respiration uses oxygen and glucose to power the activities of the cell.
Is photosynthesis a double replacement?
1 Answer. Photosynthesis is a single displacement reaction.
Are viruses capable of photosynthesis and cellular respiration?
Answer. Explanation: Viruses do not have cellular respiration, because they are not cells, which is why antibiotics do not affect viruses. Viruses do not photosynthesize, because they do not have chloroplasts or chlorophyll, whatsoever.
How do you know if a product is reactant or favored?
If the products are favored then K will be a number larger than 1. Another way to say it is that the numerator will be large or the denominator will be small. If the reactants are favored then K will be a number smaller than 1. Another way to say it is that the numerator will be small or the denominator will be large.
How are respiration and photosynthesis related to each other quizlet?
What is the relationship between photosynthesis and cellular respiration? Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back. Photosynthesis releases oxygen into the atmosphere, and cellular respiration uses that oxygen to release energy from food.
What are the similarities between cellular respiration and respiration?
Cellular respiration is not the same thing as breathing, but they are closely related. When you breathe in, you take in the When you breathe in, you take in the oxygen your cells need for cellular respiration. When you breathe out, you get rid of the carbon dioxide that your cells produce during cellular respiration.
What is the relationship between photosynthesis and respiration Class 11?
The cycle of photosynthesis as well as respiration maintains the balance of oxygen and carbon dioxide. Photosynthesis consists of the use of energy from sunlight, water as well as carbon dioxide to produce glucose and oxygen. Cellular respiration in humans uses glucose and oxygen to create carbon dioxide and water.
How are photosynthesis and cellular respiration related answers?
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.
Why is respiration considered the opposite of photosynthesis?
In respiration oxygen is involved, carbon dioxide is released and occurs all the time of day whereas in photosynthesis oxygen is released, carbon dioxide is involved and occurs in the presence of sunlight. Therefore, spiration is said to be the reverse of photosynthesis.
Is combustion single or double replacement?
Combustion reactions are the combination of some compound with oxygen to make oxides of the other elements as products (although nitrogen atoms react to make N 2). A single-replacement reaction replaces one element for another in a compound.
What do all double replacement reactions have in common?
Double replacement reactions have two ionic compounds that are exchanging anions or cations. Precipitation reactions and neutralization reactions are two common types of double replacement reactions.
How do you know something will react?
A chemical reaction is usually accompanied by easily observed physical effects, such as the emission of heat and light, the formation of a precipitate, the evolution of gas, or a color change. Absolute confirmation of a chemical change can only be validated by chemical analysis of the products!
Why do single replacement reactions occur?
A replacement reaction occurs when elements switch places in compounds. This type of reaction involves ions. Generally, more reactive elements replace less reactive elements. A single replacement reaction occurs when one element replaces another element in one compound.
Is respiration the reverse of photosynthesis?
This process – the reverse of photosynthesis is known as respiration. During respiration, sugar is broken down in a chemical reaction with oxygen. The end products of the respiration reaction are the smaller compounds of carbon dioxide and water.
How do you know if a reaction is single replacement?
To determine whether a given single replacement will occur, you must use an “Activity Series” table. If the metal or the halogen is above the element it will replace based on the activity series, a single displacement reaction will occur.
Why are photosynthesis and cellular respiration not opposite processes?
Cellular Respiration and Photosynthesis are almost opposite processes because photosynthesis removes carbon dioxide from the atmosphere while cellular respiration puts back carbon dioxide. Cellular respiration uses oxygen and has it’s waste product of carbon dioxide (CO2).
What happens to sunlight in photosynthesis?
During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.
What are the similarities between photosynthesis and aerobic respiration?
Photosynthesis and aerobic respiration are both part of a cyclic process of biochemical reactions. Photosynthesis requires the products of aerobic respiration (carbon dioxide and water), while aerobic respiration requires the products of photosynthesis (glucose and oxygen).
What are the similarities and differences between cellular respiration and fermentation?
Describe the similarities and differences between cellular respiration and fermentation. Both produce ATP through the breakdown of carbon based molecules, and both allow glycolysis to continue by recycling electron acceptors. Cellular Respiration requires oxygen and produces much more ATP than fermentation.
What is a real life example of double replacement reaction?
Double Replacement Reaction Examples An example of a double replacement reaction is the reaction between silver nitrate and sodium chloride in water. Both silver nitrate and sodium chloride are ionic compounds. Both reactants dissolve into their ions in aqueous solution.
What are two similarities between photosynthesis and cellular respiration?
What are some similarities in photosynthesis and cellular respiration? They have the same reactions but accruing in reverse. In Photosynthesis, carbon dioxide and water is yielded to glucose and oxygen. In respiration, glucose and oxygen is yielded to carbon dioxide and water.
Is combustion a double replacement?
Combustion is double replacement, on the other hand a chemical reaction is single replacement. Slow combustion is a form of combustion which takes place at low temperatures.
What determines if a single replacement reaction will occur?
where one element is substituted for another element in a compound to generate a new element and a new compound. We predict a single replacement reaction will occur when a less reactive element can be replaced by a more reactive element in a compound.
