What is an insulated device used for measuring the amount of heat absorbed or released during a reaction?
An insulated device used for measuring the amount of heat absorbed or released during a reaction is called a calorimeter.
What does it mean when delta H is a negative number?
it means that heat is released during the reaction and a + delta H means that heat is required/absorbed.
What happens to the reaction during endothermic and exothermic reaction?
During an endothermic reaction, heat is absorbed from the surroundings, causing the reaction to feel cold. The reactants have less energy than the products, so energy is absorbed to form the products. In an exothermic reaction, heat is released into the surroundings, making the reaction feel hot. The reactants have more energy than the products, so energy is released during the reaction.
Why is energy released in a exothermic reaction?
Energy is released in an exothermic reaction because bonds are being formed.
Why are Synthesis and Decomposition reactions described as opposite reactions?
Combination reactions follow the formula A + B --> AB. For example, C + O2 --> CO2. Decomposition reactions follow the formula AB --> A + B. For example, H2CO3 --> H20 + CO2.
Energy is absorbed when a nucleus is split during a nuclear reaction?
No, energy is released rather than absorbed
What is an insulated device used for measuring the amount of heat absorbed or released during a reaction?
An insulated device used for measuring the amount of heat absorbed or released during a reaction is called a calorimeter.
What does a substance break down into during a decomposition reaction?
A substance breaks down into two or more simpler substances during a decomposition reaction.
What determines whether energy will be released or absorbed during a chemical reaction?
Bond energy
How do you distinguish exothermic and endothermic processes?
By whether heat is released or absorbed during the reaction.
Is heat a form of energy released during a chemical reaction?
Yes, heat is often released or absorbed during a chemical reaction. This is because chemical reactions involve the breaking and formation of chemical bonds, and the energy difference between these bonds is released or absorbed in the form of heat.
Can energy be taken only during a chemical reaction?
Depending on the particular chemical reaction, energy may be either released or absorbed.
Can energy released during a chemical reaction be absorbed?
Yes, for ex. thermal energy.
When energy is absorbed during a chemical reaction the reaction is classified as what reaction?
endothermic reaction
Which of these occurs during an endothermic reaction?
energy is absorbed
What are the harmful effects of decomposition?
Methane gas is released, as well as carbon dioxide, during decomposition.
What is the enthalpy of reaction-?
the heat released or absorbed in a reaction
