How are photosynthesis and cellular respiration reactions in dynamic equilibrium?
Photosynthesis and cellular respiration are interconnected as the products of one process are utilized as reactants in the other. They are not in a static equilibrium but rather a dynamic equilibrium where they continuously occur simultaneously to maintain a balance in the availability of energy and nutrients in the ecosystem. This balance ensures the cycling of carbon and energy between producers and consumers in the environment.
Why limiting reactant is not applicable to reversible processes?
In reversible processes, reactants can convert back and forth into products, making it difficult to distinguish a limiting reactant. The system reaches equilibrium with both reactants present, rather than one being completely consumed. Therefore, the concept of a limiting reactant does not apply to reversible processes.
Is a chemical equation balanced by changing or adding?
The subscripts determine what the chemicals are, you have to change the amount of the reactants/products rather than change what the reactants/products actually are eg O2 is oxygen gas, if you wanted 4 of them to balance it it would have to be 2 O2 otherwise it wouldn't be oxygen gas any more.
What is a general word equation?
A general word equation is a way to represent a chemical reaction using words, rather than chemical formulas or symbols. It provides a simple description of the reactants, products, and overall process of the reaction, without specifying the exact compounds involved.
Why do most complex organisms undergo aerobic respiration rather than anaerobic respiration?
During anaerobic respiration, such as fermentation, pyruvic acid and NADH form the products of alchohol and carbon dioxide and NAD+. In aerobic respiration there are many more steps in the Krebs cycle to make the products of carbon dioxide, NADH, ATP, and FADH2 from pyruvic acid.Therefore aerobic respiration is much more complex than aerobic respiration.

When there are two or more reactants or prducts arethey separated by an arrow?
In a chemical reaction, reactants are typically separated from products by a plus sign (+) rather than an arrow. The arrow is used to indicate the direction of the reaction, showing the conversion of reactants to products.
In an exothermic reaction is the energy of the products higher or lower than that of the reactants?
In an exothermic reaction the energy of the products is less than that of the reactants.
Why can photosynthesis and respiration be considered reverse process?
Photosynthesis (water + carbon dioxide + sunlight ---> oxygen + sugar) and respiration (oxygen + sugar ---> water + carbon dioxide) are considered reverse processes because the reactants for photosynthesis are the products of respiration and the reactants for respiration are the products of photosynthesis.
Does chemical reactions make new materials called the reactants?
Hi there! Well, to answer your question, chemical reactions invlove two sets of substances: the reactants and the products. The reactants are the chemicals that are involved BEFORE the reactions occurs. The products are the chemicals that are formed as a result of the chemical reaction. In another words, the products are your end results. Therefore, chemicals reactions make new materials called the PRODUCTS, rather than reactants. For example in photosynthesis: Glucose + Oxygen -----> Carbon dioxide + Water Glucose and oxygen are your reactants, whereas carbon dioxide and water are your products.

What happens when a base is added to water and the position of equilibrium lies to the left?
When a base is added to water and the equilibrium position shifts to the left, it means that the reaction is favoring the formation of the reactants rather than the products. This indicates that the base is not fully dissociating in water and the concentration of the reactants is higher than the products.
Do reactants disappear during a chemical reation?
If you have a simple generic reaction such asA + 2B ---> 3C + 4DThen the rate is:RATE = -d[A]/dt = -1/2 d[B]/dt = 1/3 d[C]/dt = 1/4 d[D]/dtwhere the "[A]" means the concentration of A.
Albert remembers his teacher stressing that the arrow in a chemical equation does not mean equal instead he said the arrow meant what?
The arrow in a chemical equation represents the direction of the reaction, indicating that reactants are turning into products. It shows the flow of reactants converting into products, rather than implying equality between the two sides of the equation.
Why do you need to convert mass to moles in stoichiometry problems?
Converting mass to moles in stoichiometry problems is necessary to determine the amount of reactants or products involved in a chemical reaction. This conversion allows you to compare the amounts of different substances based on their molar quantities rather than their masses, making it easier to balance equations and calculate the quantities of reactants needed or products produced.
How does the equation for cellular respiration compare with the equation for photosynthesis?
The equation for cellular respiration is C6H12O6 + 6O2 --> 6CO2 + 6H2O + energy. The equation for photosynthesis is 6H2O + 6CO2 + Light Energy -> C6H12O6 + 6O2. Cellular respiration does not require light energy, and photosynthesis does.
