What else can I help you with?
What would likely happen if you were to touch the flask in which an exothermic reaction were occurring?
The flask might feel cool to the touch as the reactants absorb heat conducted through the flask from your body. (This assumes that the reaction is happening at temperatures below your body temperature.)
What identifies an exothermic reaction?
Temperature increasesNegative energy changereactant's energy is higher than productsMore energy is released to form bonds (products) than energy absorbed to break bonds (in reactants)from my revision :D
What is enothermic?
An endothermic reaction absorbs heat energy from its surroundings, causing a decrease in temperature. This type of reaction typically feels cold to the touch as it takes in heat from the environment to proceed.
Is a burning candle exothermic reaction?
Yes, a burning candle is an example of an exothermic reaction. When the candle wax reacts with the oxygen in the air, it produces heat and light energy as byproducts. This release of heat is what makes the candle flame feel warm to the touch.
What type of reaction gives off heat Does it feel hot or cold?
Endothermic reactions increase their enthalpy by absorbing heat
A reaction that gives out energy?
An exothermic reaction is a reaction that releases energy in the form of heat or light. This type of reaction usually feels warm to the touch and may involve combustion or decomposition of reactants. Examples include burning wood, rusting iron, and neutralization reactions.
What are the signs of an exothermic reaction?
The reaction vessel will warm/hot to the touch. 'Exothermic' ; het coming out. Conversely, if the reaction vessel feels cool/cold to the touch it is Endothermic ; taking in heat from its surroundings.
What is a sentence using the word exothermic reaction?
The compound then produced an extreme exothermic reaction, which singed the eyebrows of the unfortunate scientist standing next to it.

Describe energy in an exothermic reaction?
In an exothermic reaction, energy is released to the surroundings in the form of heat. This results in a decrease in the overall energy of the system, as the reactants have more energy than the products. Exothermic reactions typically feel warm to the touch and can sometimes involve the emission of light.
What is enothermic?
An endothermic reaction absorbs heat energy from its surroundings, causing a decrease in temperature. This type of reaction typically feels cold to the touch as it takes in heat from the environment to proceed.
Is a burning candle exothermic reaction?
Yes, a burning candle is an example of an exothermic reaction. When the candle wax reacts with the oxygen in the air, it produces heat and light energy as byproducts. This release of heat is what makes the candle flame feel warm to the touch.
What is a chemical reaction that's absorbs energy called?
An Endothermic reaction. If you touch the reaction vessel it will feel cool/cold, as it is taking in heat energy. By contract an Exothermic reaction is one that gives out heat. If you touch the reaction vessel it will feel warm/hot as it is liberating heat energy.
Is a test tube that feels cold to touch after two substances have been mixed is exothermic?
NO. If the test tube becomes hot, then the reaction taking place in the test tube is EXOTHERMIC. The reaction is releasing heat to the surroundings, and the test tube is part of the surroundings.
When a white powder is added to a liquid in a beaker at room temperature the beaker becomes too hot to touch What kind of reaction is this an example of?
Exothermic?
What type of reaction gives off heat Does it feel hot or cold?
Endothermic reactions increase their enthalpy by absorbing heat
