What reaction occurs when chemical bonds between atoms are broken?
When chemical bonds between atoms are broken, a chemical reaction called a decomposition reaction occurs. In this reaction, the bonds holding the atoms together are broken, leading to the formation of new products. The original reactants are broken down into simpler substances.
What principle of chemistry states that if a chemical reaction occurs in stages then the heat of each step will equal the total heat of the reaction as if it had occurred in one step?
Hess's Law states that the total enthalpy change for a chemical reaction is the same regardless of the pathway taken to achieve the final products. This means that if a reaction occurs in multiple steps, the sum of the enthalpy changes for each step will equal the overall enthalpy change for the reaction.
How can you tell if a chemical reaction has taken place when a hot air balloon flies?
When a hot air balloon flies, the chemical reaction that occurs is the heating of the air inside the balloon, causing it to expand and become less dense than the surrounding air. This creates lift, allowing the balloon to rise. You can confirm that a chemical reaction has taken place by observing the change in volume and buoyancy of the air inside the balloon as it heats up.
What is the opposite of reactants?
When a chemical reaction takes place, it starts with chemicals which are called reactants, literally meaning those which react, and after the reaction has taken place you then have chemicals called products, because they were produced by the reaction.
A reaction in which energy is taken in?
An endothermic reaction is one in which energy is taken in from the surroundings to drive the reaction. This type of reaction requires an input of energy to proceed. It often results in a decrease in temperature of the surroundings.
What is precautions?
Precautions refers to certain measures that are taken in advance to prevent something inconvenient or unpleasant from happening.
What is the action taken by stimulus?
Reaction
What is A reaction which energy is taken in?
endothermic
What evidence is there to show that a chemical reaction has taken place when an egg is cooked?
The change in color indicates that a chemical reaction has taken place.
When this type of reaction occurs oxygen is taken away from a substance and electrons are gained by the substance?
The type of reaction being described is reduction. In a reduction reaction, a substance gains electrons and its oxidation state decreases. Oxygen is often the oxidizing agent in these reactions, causing another substance to lose electrons as it is oxidized.
What reaction will you be taking out if your metal is copper?
what reaction would be taken out if you had copper as your metal
What is a statement of hesses law?
C - The enthalpy of reaction does not depend on the steps taken in the reaction. APEX --WXM--
