How is rusting in an enothermic reaction applied in everyday life?
Rusting is an eXothermic reaction, not an eNDothermic.
What are differences between endothermic and exothermic reactions examples?
The main differences between exothermic reactions and endothermic reactions are: Exothermic reactions are reactions that give off energy (light, electrical or mainly heat), causing the surroundings to warm up. Endothermic reactions are reactions that absorb energy, causing the surroundings to cool down. The products of an exothermic reaction have less energy, or less total enthalpy, than of it's reactants. This is due to the reactants containing more stored energy because energy from external sources is not required. This also gives the products more stability because in order to achieve a reversible reaction and break the chemical bonds of the products, you will need to apply more energy to it. The opposite is for endothermic reactions. The products of the reaction have a greater total enthalpy of the reactants, causing the reactants stored energy to decrease. This produces less stable products that need less energy to break their bonds in a reversible reaction. Finally most exothermic reactions are spontaneous, where as most endothermic reactions are not spontaneous as they generally need energy applied to them before they start.
If the mass of an object does not change a constant net force on the object produces a constant what?
If the mass of an object does not change, a constant net force applied to the object will produce a constant acceleration according to Newton's Second Law (F=ma). This means that the object will continue to accelerate at a constant rate as long as the force is applied.
Does the density the mass or the volume decrease when heat is applied?
When heat is applied, the density of a substance generally decreases because the particles gain more energy and move farther apart, increasing the volume. Mass remains constant unless there is a chemical reaction or phase change.

Give an endothermic reaction?
In thermodynamics, the word endothermic "within-heating" describes a process or reaction that absorbs energy in the form of heat. Its etymology stems from the Greek prefix endo-,meaning "inside" and the Greek suffix -thermic, meaning "to heat". The opposite of an endothermic process is an exothermic process, one that releases energy in the form of heat. The term "endothermic" was coined by Marcellin Berthelot.The concept is frequently applied in physical sciences to e.g. chemical reactions, where thermal energy (heat) is converted to chemical bond energy.Endothermic, also incorrectly known as chemical reaction in which a system receives heat from the surroundings: Q > 0When this occurs at constant pressure:∆H > 0and constant volume:∆U > 0If the surroundings do not supply heat (e.g., when the system is adiabatic), an endothermic transformation leads to a decrease in the temperature of the system.[1]Endothermic processesSome examples of endothermic processes are:Depressurizing a pressure canA chemical cold pack consisting primarily of ammonium nitrate and water.Melting of icevaporization of waterImplications for chemical reactionsChemical endothermic reactions need heat to be performed. In a thermochemical reaction that is endothermic, the heat is placed on the reactants side (heat is necessary for and absorbed during the reaction).
In figure 19 the endothermic reaction that breaks downs mercury (II) oxide into mercury and oxygen can be classified as a reaction.?
The endothermic reaction that breaks down mercury (II) oxide into mercury and oxygen is classified as a decomposition reaction. In a decomposition reaction, a single compound breaks down into two or more simpler substances. In this case, mercury (II) oxide decomposes into mercury and oxygen when heat is applied to the system.
Is baking bread exothermic or endothermic?
Baking bread is an exothermic process. During baking, heat is applied to the dough causing chemical reactions to occur, such as the Maillard reaction and caramelization, which release heat energy in the form of steam and heat, resulting in the bread rising and forming a crust.
Why do cold packs feel cold?
In a chemical ice pack you have to break some sort of seal so that two chemicals react. The chemicals that are used are chosen because when mixed they create an endothermic reaction causing it to feel cold
What will the mass and acceleration produce if the applied force is constant?
If the applied force is constant, the acceleration will also be constant. To know the actual amount of acceleration, you divide the force by the mass.
How does the chemical potential energy if a system change during an endothermic reaction?
During an endothermic reaction, the chemical potential energy of the system increases. This is because energy is absorbed from the surroundings in the form of heat, resulting in higher potential energy within the system.

Where do agricultural chemicals flow?
Agricultural chemicals typically flow into the ground if they are well applied. However, they may end up in streams if they are poorly applied or if there is a flood.
Does the acceleration remain constant if the applied force was increasing?
No. Acceleration is proportional to the applied force.
How does the spring constant change when a greater force is applied?
When a greater force is applied, the spring constant remains constant for an ideal spring. However, in real springs, the spring constant may change slightly due to factors like deformation or material properties.
If the mass of an object does not change a constant net force on the object produces a constant what?
If the mass of an object does not change, a constant net force applied to the object will produce a constant acceleration according to Newton's Second Law (F=ma). This means that the object will continue to accelerate at a constant rate as long as the force is applied.
