How does the temperature change during an exothermic reaction?
During an exothermic reaction, the temperature increases because heat is released as a byproduct of the reaction.
What are the subatomic articles that can change in a nuclear reaction?
The subatomic particles that can change in a nuclear reaction are protons, neutrons, and electrons. During nuclear reactions, these particles can be gained or lost, leading to the formation of different elements and isotopes.
What parts of an atom can change during a nuclear reaction that can't change in a chemical reaction?
the number of protons and neutrons
During nuclear reaction two protons change into what?
In the nuclear fusion process in the sun, two protons change into a proton and a neutron, plus also a positron and a neutrino. This is part of the synthesis of helium and release of energy which powers the sun. You can see the complete chain of reaction at the link below
How can one determine the heat of reaction?
The heat of reaction can be determined by measuring the temperature change that occurs during a chemical reaction. This can be done using a calorimeter, which is a device that can measure the heat released or absorbed during a reaction. By monitoring the temperature change and using the specific heat capacity of the substances involved, the heat of reaction can be calculated.
What is the sign of ΔT in an endothermic reaction?
ΔH is the enthalpy of the reaction and will be positive in an endothermic reaction and negative in an exothermic reaction.ΔT designates a change in temperature. T2-T1 = ΔTOften the change in temperature will be negative for an endothermic reaction.
How can one determine the change in enthalpy of a reaction?
The change in enthalpy of a reaction can be determined by measuring the heat released or absorbed during the reaction. This is typically done using a calorimeter, which allows for the precise measurement of the temperature change that occurs. The change in enthalpy is then calculated using the heat capacity of the system and the temperature change.
How will you judge whether a chemical reaction is exothermic or endothermic in nature?
A chemical reaction is exothermic if it releases heat to its surroundings, causing an increase in temperature. On the other hand, a reaction is endothermic if it absorbs heat from its surroundings, resulting in a decrease in temperature. This can be determined by measuring the temperature change during the reaction or by analyzing the enthalpy change of the reaction.
How can you determine whether or not a chemical reaction is exothermic?
You can determine if a chemical reaction is exothermic by measuring the temperature change of the surroundings. If the temperature increases during the reaction, then it is exothermic. Additionally, you can look for the release of heat or light during the reaction as indicators of an exothermic process.
How should a student use a thermometer to determine if a reaction is exothermic?
To determine if a reaction is exothermic, a student should use a thermometer to measure the temperature change during the reaction. If the temperature increases, it indicates that the reaction is exothermic, releasing heat.
What was the temperature of the chernobyl nuclear power plant meltdown?
During the Chernobyl nuclear power plant meltdown, temperatures reached up to 4000 degrees Celsius in the reactor core due to the uncontrolled nuclear chain reaction.
What two quantities do not change during a nuclear reaction?
During a nuclear reaction, the two quantities that do not change are the total mass-energy and the total charge. According to the law of conservation of mass-energy, the total mass-energy before and after the reaction remains constant, while the conservation of charge principle ensures that the total electric charge is conserved throughout the process. These principles govern the behavior of nuclear reactions and ensure that fundamental properties remain unchanged.
