What else can I help you with?
What will be the consequences of adding or removing a reactant or aproduct from a reaction that is at dynamic equilibrium?
if reaction is at equ. then adding product will cause reaction to proceed forward and product will increase and removing product will do the same while removing reactant will cause reactn 2 proced bakward and reactant will increase and adding product wl do the same it is in accordnc wth LeChateliars principle
What is a change which means the products can't be returned back to the reactants?
A change that makes it difficult or impossible for products to revert back to reactants is increasing the temperature to exceed the activation energy barrier for the reverse reaction, altering the pH to a level that favors product stability, or physically removing the product from the reaction environment.
What type of chemical reaction occurs when polymer apart by water?
Dehydration synthesis, also called condensation, is the type of reaction that builds polymers by removing water.
What reaction requires energy - dehydration or hydrolysis?
Dehydration reaction requires energy because it involves removing water to bond two molecules together. Hydrolysis reaction releases energy as water is added to break a bond between molecules.
What is the term for the type of enzymatic reactions in which substrates are joined together to form the products?
This type of enzymatic reaction is known as a condensation reaction. It involves the joining of substrates by removing a water molecule to form the products.

Which of these is reversible heating burning or neither?
Burning is not reversible because it involves a chemical reaction that permanently changes the substances involved. Heating, on the other hand, is reversible since it involves providing energy to increase the temperature but can be reversed by removing the heat.
Is filtering a reversible or irreversible change?
Filtering is a reversible change because it can be undone by simply removing the filter and allowing the substances to mix again.
What reaction would represent dephosphorylation?
Dephosphorylation is the process of removing a phosphate group from a molecule. For example, the reaction catalyzed by a phosphatase enzyme can dephosphorylate a substrate by removing the phosphate group from it, typically using water as a reactant. This reaction decreases the phosphorylation state of the molecule, impacting its biological activity and signaling.
Why reflux a reaction mixture?
Refluxing a reaction mixture helps to maintain a constant temperature and ensure that the reaction proceeds smoothly. It also allows for volatile components to be continuously evaporated and condensed back into the reaction flask, preventing loss of reactants or products. Additionally, refluxing can help drive reversible reactions forward by removing byproducts.
What would increase the concentration of reactants?
It means that there will be more particles of the reactants in the vessel, so they are more crowded and collisions of the right energy are more likely. or collisions of the right energy are more likely.
Is breaking a window reversible?
Yes, breaking a window is reversible by replacing the glass with a new one. The process involves removing the broken glass shards, fitting a new pane of glass, and securing it in place.
How will decreasing the reactant concentration affect the reaction?
It depends on the order of the reaction. If it is zero order, decreasing the reactant concentration will have NO effect on the rate. If it is 1st or 2nd order (or more), then decreasing the concentration will DECREASE the reaction rate.
Can you speed up a reaction?
Heat up (temperature change) or adding a catalyst or enzyme (in biological reactions). Further more: mixing and grinding for solid state reactions, higher concentrations (in 'non-zero' order reactions) and higher pressure in gas reaction. At last: more reactant and removing product might help in some cases.
What are the reversible effects of adding heat?
The reversible effects of adding heat include changes in temperature, phase transitions (such as melting or boiling), and changes in chemical reactions. These effects can be reversed by removing the heat source or by cooling the system.
Removing an reactant from a system at equilibrium will?
If reactants are removed (thus taken away from the left side) the equilibrium moves 'to counteract' the reason of disturbance: removing is countered by forming back:So this eq'b'm. will move to the LEFT (
How does a change in the amount of a product cause shift in equilibrium?
Most chemical reactions naturally settle to a certain equillibrium, the point where the forward reaction rate equals the reverse reaction rate such that no further evidence of reaction can be observed macroscopically. The equilibrium can be shifted far to the products side (or right), meaning that a majority of the molecules in an environment are the desired product. A good example is the combustion of methane, the equilibrium for the combustion is extremely far to the right and thus most of the methane molecules undergoe reaction. However, many chemical equilibriums are not so extreme to either side and thus a good amount of both product and reactant will be present. By removing some of the product by a technique such as distillation, the chemical environment will no longer be in equilibrium anymore. Because of this the reaction will begin to proceed again forming enough product to reestablish the favorable equilibrium. In this manner reactions can be forced to the product side and product yields that were may have been considerably lower can be significantly improved.
