Is Gas produced from a reaction is a phase change and not a chemical change.?
A gas released during a chemical reaction is a chemical change.
What is a correct description of the enthalpy of reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
What is a correct description of enthalpy of a reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
What types of properties change during a chemical reaction?
During a chemical reaction, properties that can change include color, temperature, state of matter (solid, liquid, gas), odor, and the formation of new substances with different chemical properties.
Is burning newspaper a physical change?
Yes, burning newspaper is a chemical change because it undergoes a chemical reaction (combustion) that changes its chemical composition. The heat and flame produced during burning are evidence of this chemical reaction taking place.
What undergoes no chemical change during a chemical reaction?
A catalyst undergoes no chemical change during a chemical reaction.
Is Gas produced from a reaction is a phase change and not a chemical change.?
A gas released during a chemical reaction is a chemical change.
What undergo no chemical change during a chemical change?
Catalysts doesn't undergo a chemical change during a chemical reaction.
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
What goes under no chemical change in a chemical reaction?
Mono-atomic ions do not undergo a chemical change during a chemical reaction.
Substances are changed into different substances when bonds break and form during?
Chemical bonds are made and broken by chemical reactions. After chemical bonds have been broken, then energy is released, and if a chemical bond is made, then energy is absorbed.
What is it that undergoes no chemical change during a chemical reaction?
A catalyst does no change chemically.
How to calculate the change in enthalpy during a chemical reaction?
To calculate the change in enthalpy during a chemical reaction, subtract the sum of the enthalpies of the reactants from the sum of the enthalpies of the products. This difference represents the change in enthalpy for the reaction.
What is the description of the enthalpy of a reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
What is the description of the enthalpy of reaction?
The enthalpy of a chemical reaction is the change of heat during this reaction.
Can a material change from one substance to another during a chemical reaction?
"Substance" is too fuzzy a word. Chemical reactions can change materials into other compounds, for example shiny iron into rust (Fe2O3). But it cannot change an element into another element. A nuclear reaction can do that, for example uranium into plutonium.
What change could happen during a chemical reaction?
the chemical shall be changed
