What else can I help you with?
Does the change of temperature will slow or faster the chemical reaction?
No, an increase in temperature will speed up the reaction. This is because the heat energy is transferred into kinetic energy (movement energy) in the reactors and this increases their speed and so increases the rate at which they collide with each other, increasing the rate of the chemical reaction.
What is the lowest temperature flame that can be produced by a chemical reaction?
The lowest temperature flame that can be produced by a chemical reaction is around 600 degrees Celsius.
How might a thermometer help you decide if there was any chemical change on mixing iron and charcoal?
For a chemical change to occur, there must be a chemical reaction. A chemical reaction would be either endothermic (uses energy, mostly heat), or exothermic (produces energy, again mostly heat). Any change in temperature of the reactants, as measured by a thermometer, will tell you not only ifa chemical reaction occurred, but also which kind of chemical reaction. No temperature change usually indicates that no reaction has occurred, a decrease in temperature would indicate an endothermic reaction, while an increase in temperature would indicate an exothermic reaction.
Does volume of water affect temperature rise in reaction between calcium oxide and water?
Yes, the volume of water can affect the temperature rise in the reaction between calcium oxide and water. A larger volume of water can absorb more heat energy released during the reaction, resulting in a lower temperature rise compared to a smaller volume of water. Additionally, the concentration of the resulting calcium hydroxide solution can also influence the temperature change.
What is definition of exothermic?
Exothermic refers to a chemical reaction or process that releases heat to its surroundings, resulting in a rise in temperature. In an exothermic reaction, the products have lower energy than the reactants, and the excess energy is released as heat.
Does temperature rising in a chemical mixer have to do anything with a chemical reaction?
Yes, a rise in temperature in a chemical mixer can influence the rate and extent of a chemical reaction. Increased temperature generally increases the kinetic energy of molecules, which can lead to more frequent collisions and higher chances of successful collisions between reactant molecules, thus speeding up the reaction. However, the specific effect of temperature on a reaction depends on the reaction kinetics and thermodynamics of the system.
Aluminium and sodium chloride temperature when mixed- does it rise or not?
When aluminum and sodium chloride are mixed, a chemical reaction can occur, especially in the presence of water, leading to the release of heat. This exothermic reaction typically causes the temperature of the mixture to rise. However, if the mixture is dry and no reaction occurs, the temperature may not change significantly.
A chemical reaction is termed exothermic if?
A chemical reaction is termed exothermic if it releases heat to its surroundings, resulting in a rise in temperature. This is usually accompanied by the system losing energy to its surroundings in the form of heat.
What hypothesis for a method in investigating a factor that affects the temperature of a chemical reaction?
The rise in temperature is affected by the amount of anhydrous sodium carbohydrate added to 20ml of water
What changes in an exothermic chemical change?
In an exothermic chemical reaction, heat is released to the surroundings. This results in an increase in temperature, which can be observed as a rise in temperature of the surroundings. Additionally, the products of the reaction typically have lower energy than the reactants.
How are temperature and the Arrhenius theory related?
The reaction rate of a chemical reaction is dependent on temperature.
Does the change of temperature will slow or faster the chemical reaction?
No, an increase in temperature will speed up the reaction. This is because the heat energy is transferred into kinetic energy (movement energy) in the reactors and this increases their speed and so increases the rate at which they collide with each other, increasing the rate of the chemical reaction.
Do catalysts affect temperature?
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
What is an exothemic reaction?
An exothermic reaction is a chemical reaction that releases heat to its surroundings. This can result in an increase in temperature, which is often observed as the reaction occurring with the evolution of heat or as the surroundings feeling warm.
What happens to a cake in the oven that causes it to rise?
A chemical reaction.
What is the lowest temperature flame that can be produced by a chemical reaction?
The lowest temperature flame that can be produced by a chemical reaction is around 600 degrees Celsius.
What is a chemical reaction is endothermic?
An endothermic reaction is a chemical reaction that absorbs energy. Such reactions usually produce a temperature drop.
