Why is vigorous stirring or emulsion formation necessary in a phase-transfer reaction?
The purpose of phase-transfer catalysts is to dissolve ionic compounds in organic solvents and vice versa. You need that emulsion formation as a sign that it's working, and the vigorous stirring helps form those emulsions.
This is the necessary heat for this reaction.
its bcoz it helps them to photosynthesize. A reaction takes place which is responible for glucose formation
Some indicators of a chemical reaction are: - change of color - change of odor - release of a gas - change of the temperature - change of the viscosity - formation of a precipitate - change of general appearance - possible explosion - possible chemiluminescence -formation of new compounds
Formation of choloform is endothermic or exothermic reaction?
A standard formation reaction is the reaction of the ions which make up a compound in their standard states. For example, the standard formation reaction of H2SO4 is: 2H+(g) + SO42-(g) --> H2SO4 (l)
Emulsion, Solution, Suspension, Addition and Condensation polymerization.
How is the enthalpy of reaction related to the enthalpies of formation for the products and reactants?
The difference between the enthalpy of formation of the products minus the enthalpy of formation of the reactants is the enthalpy of the reaction
The formation of bubbles suggests that at least one of the products of the reaction is a gas
What chemical processes can lead to the removal of ions from solution and thus drive a metathesis reaction?
The formation of a gas that escapes the system, the formation of a precipitate, or the formation of water can drive a double displacement reaction (metathesis reaction) to completion.
A formation reaction :) Decomposition implies the breakdown of a compound, formation implies the production of a compound.
The formation of a solid product from reaction of at least two components of a fluid phase. The final fluid phase in which reaction occurs is usually obtained by mixing at least two distinct fluid phases each of which is missing at least one of the necessary components of reaction but which together contain all the required components for the reaction.
Another name for a composition reaction is a formation reaction.
Evidence of a chemical reaction include the following: formation of a precipitate formation of a gas change in temperature change in color
formation of precipitate is a chemical reaction
A chemical reaction is: C2H4 + H2O → C2H5OH
A gas-evolution reaction is a reaction that results in the formation of a gas.
Formation of a precipitate is evidence of a chemical reaction.
Bond formation of exothermic.
There are many observable characteristics of a chemical reaction. They are: change in temperature formation of a precipitate change in color formation of a gas formation of a new odor disappearance of a solid
The yield of a reaction is the final product. It is necessary to find the percent yield of a reaction since the efficiency of the reaction can be determined.
Formation of a precipitate, color change, gas formation, and temperature change are indications that a chemical reaction has occurred.
The type of chemical reaction that takes place through the formation of the rubber is called the mechano-chemical reaction. Through this, it gives the end product a three dimensional structure.
The formation of large molecules from small repeating units is known as a condensation reaction. A condensation reaction is also known as dehydration synthesis.
Probably an explosive reaction with the formation of francium hydroxide.
Its is a chemical reaction because you can not take out what you but into the butter.
its reaction is by certain bacteria (mainly lactobacillus )
Salt formation reaction, reducto-oxidative reaction (redox)
The formation of a gas causes fizzing in a chemical reaction.
This is a precipitation reaction and involve the formation of an insoluble compound.
The energy necessary to initiate a chemical reaction is called "activation energy."
They're two totally different tests. The alcohol emulsion test is for fat, and it works because water and oil don't mix. The reaction in the Benedict's test requires heat to work.
Four indicators that a chemical reaction is taking place are........ Formation of gas Formation of solid Energy Change Color Change
The formation of water form hydrogen and oxygen: 2H2 + O2 --> 2H2O The formation of sodium chloride from sodium and chlorine: 2Na + Cl2 --> 2NaCl
What happens when in a reversible reaction the rate of product formation is equal to the rate of reactant formation?
then we experience equilibrium
this reaction leads to the formation of calcium hydroxichloride.
The formation of ADP and inorganic phosphate from ATP and water is an example of which kind of reaction?
It is a Hydrolysis reaction.
Not a chemical reaction, but the formation of a water solution of hydrofluoric acid.
The creation of bubbles in a liquid can result from: Boiling (formation of gas phase material) a physical change Dissolution of dissolved gasses (a physical change) from a liquid as it warms The creation of gases by reactants in an aqueous environment (chemical change)
Remove the source of the allergic reaction and if necessary use an antihistamine to counter it. In a serious reaction, using an Epipen to inject antihistamine into the body may be necessary.
The thickening is caused by the formation of a precipitate. The formation of a precipitate is a chemical reaction.
color change formation of a precipitate temperature change formation of gas bubbles
The synthesis of ATP requires free energy which makes it a endothermic reaction.
What is the kind of reaction between two aqueous solutions that results in the formation of a solid compound?
It is a Precipitation reaction.
1. Formation of a solid 2. Formation of water (H2O) 3. Transfer of electrons 4. Formation of a gas
Neutralization is the reaction between an acid and an alkali. Neutralization usually results in the formation of a salt from the reaction.
