Is the chemical reaction for aluminum exothermic or endothermic?
Yes it is. When these two chemicals react, the container they are in becomes heated. Exothermic refers to a release of heat and energy.
Why does methanol show an exothermic reaction with water at room temperature while it gives an endothermic reaction with water in cold conditions?
Methanol can form hydrogen bonds with water molecules, leading to an exothermic reaction due to the release of energy when the bonds are formed. In colder conditions, the stronger hydrogen bonds between water molecules dominate, requiring energy to break these bonds to accommodate methanol molecules, resulting in an endothermic reaction.
What does edothermic and exothermic mean?
Endothermic means that the reaction absorbs heat from the surroundings, and requiring energy be added to it in order for it to take place. An Exothermic reaction, however, releases heat into the surroundings as a result of the reaction.
What type of reaction occurs when two chemicals react together and the temperature decreases?
Endothermic reaction
What H2O(l) plus heat H2O(g) exthermic or endothermic?
It is an exothermic reaction. There are multiple ways to think about this. The reactants are in the gas phase and thus have a lot of energy within the molecules. When they react to produce a liquid, which has much less energy in its molecules. The energy must be released to the environment to lower the energy of the bonds.
Is Grilling hamburgers a endothermic or exothermic reaction?
its endothermic, it needs heat to react.
Is a hand warmer pack an endothermic reaction?
Exothermic. It release heat in the process.
When iron rusts is it an endothermic or exothermic reaction?
It is an endothermic reaction because in endothermic reaction energy is added .In that reaction nitrogen does not react with oxygen without energy added in the shape current . In that reaction 3000`current is applieded to take reaction b/w nitrogen and oxygen
When acid and base react what happens to the temperature?
When an acid and a base react, there is a possibility of an exothermic or endothermic reaction occurring, depending on the specific acids and bases involved. An exothermic reaction releases heat energy, leading to an increase in temperature, while an endothermic reaction absorbs heat energy, causing a decrease in temperature.
Is a candle a endothermic or exothermic change?
exothermic- because exothermic gives off heat and endothermic is cold
Is the chemical reaction for aluminum exothermic or endothermic?
Yes it is. When these two chemicals react, the container they are in becomes heated. Exothermic refers to a release of heat and energy.

Take about 2 g barium hydroxide in a test tube. Add 1 g of ammonium chloride and mix with the help of a glass rod. Is this an exothermic or an endothermic reaction?
This is an endothermic reaction. When barium hydroxide and ammonium chloride are mixed, they react to form barium chloride, ammonia, and water. This reaction absorbs heat from the surroundings, causing a decrease in temperature.
When hydrocholoric acid and sodium hydroxide react is it exothermic?
Yes, it is an exothermic reaction.
What does edothermic and exothermic mean?
Endothermic means that the reaction absorbs heat from the surroundings, and requiring energy be added to it in order for it to take place. An Exothermic reaction, however, releases heat into the surroundings as a result of the reaction.
How do endothermic and exothermic differ?
Exothermic reactions release energy (usually as heat) into the surrounding environment - endothermic reactions absorb energy from the surrounding environment. Note that exothermic reactions are capable of turning into runaway reactions as the heat of reaction often speeds up the rate of reaction (releasing more heat, etc). Endothermic reactions are, usually, self moderating as a limited amount of energy is capable of being drawn from the surrounding environment.
What is an exothermic reaction?
An exothermic reaction is a chemical reaction that is done by the release of heat. It gives out energy to its surroundings. The energy needed for the reaction to occur is less than the total energy released.
