What else can I help you with?
A neutralization reaction was carried out in a calorimeter The temperature of the solution rose from 20.0 C to 25.6 C Is this reaction endothermic or exothermic?
This reaction is exothermic because the temperature of the solution rose. In an exothermic reaction, heat is released to the surroundings, causing an increase in temperature.
The haber process is typically carried out at a temperature of 500 Celsius so what would happen if 100 Celsius?
If the Haber process were carried out at 100 degrees Celsius instead of 500 degrees Celsius, the reaction rate would be significantly slower. Lower temperatures would reduce the efficiency of the process, resulting in lower production rates of ammonia. It may also affect the equilibrium position of the reaction, favoring the reverse reaction.
How can the enthalpy change be determined for a reaction in an aqueous solution?
Utilizing a thermometer to measure the temperature change of the solution can be used (along with the mass of the reactant(s)) to determine the enthalpy change for an aqueous reaction, as long as the reaction is carried out in a calorimeter or similar apparatus so that no external heat is added or removed from the system.
Would an exothermic reaction be more favord or less favored if it were carried out within a superheated chamber?
An exothermic reaction would likely be less favored in a superheated chamber because the increased temperature would promote the reverse endothermic reaction, shifting the equilibrium away from the desired product in favor of the reactants.
Why are exothermic reactions carried out at low temperature?
Exothermic reactions release heat energy during the reaction. By carrying out these reactions at low temperatures, it helps to control the rate of reaction and prevents overheating or loss of control over the reaction. It also reduces the risk of side reactions and improves the overall yield of the desired product.

why are many industrial reaction carried out at high tempratureexplain the reason by having given illustrated example?
Because if the temperature is increased, the equilibrium position moves in the direction of the endothermic reaction. and if the temperature is low the reaction would be slow.
Why is synthesis of p-nitro acetanilide carried out at low temperature?
Synthesis of p-nitro acetanilide is carried out at low temperature to minimize side reactions and to control the rate of the nitration reaction. Low temperature helps to improve the selectivity of the reaction, favoring the desired product formation over potential byproducts.
What is it called when two substances are mixed and a temperature change occures?
Usually such an experiment is carried out to find the change in enthalpy of the reaction.

How much oxygen is in a tank on an airplane?
Oxygen in an airplane is not carried in a tank, it is the result of a chemical reaction. The oxygen will last for approximately ten to fifteen minutes.

When might you need to use a thermometer in a lab?
You might need to use a thermometer in a lab to measure the temperature of a sample or solution, monitor the temperature of a reaction, or ensure that a process is carried out at a specific temperature for accuracy and reproducibility of results.
How is the reduction of ketones with sodium borohydride typically carried out in organic chemistry reactions?
In organic chemistry reactions, the reduction of ketones with sodium borohydride is typically carried out by adding the ketone to a solution of sodium borohydride in a suitable solvent, such as ethanol or methanol. The reaction is usually performed at room temperature or slightly elevated temperatures, and the resulting product is often isolated by simple workup procedures like filtration or evaporation.
How is exothermic reaction identified?
An exothermic reaction is identified by a release of heat energy. This can be observed by a temperature increase in the surroundings, production of light or sound, or feeling warmth. Additionally, exothermic reactions often result in a negative change in enthalpy (ΔH).
How can the process of reducing an ester be effectively carried out?
The process of reducing an ester can be effectively carried out by using a reducing agent, such as lithium aluminum hydride or sodium borohydride, in a suitable solvent under controlled conditions of temperature and pressure. This reaction typically involves the addition of the reducing agent to the ester, followed by the removal of any byproducts to yield the desired product.
Is the work done in isothermal system is zero why?
If a reaction is carried out in constant temperature and constant volume no work is done and heat exchanged with surroundings is equal to the internal energy.
