What kind of chemical reaction is exothermic reaction?
An exothermic reaction is one that proceeds with the evolution of heat.
The arrow in a chemical reaction is?
The arrow is an indication for the sense of reaction.
Why would more reactive metal take longer to thermally decompose?
A more reactive metal would take longer to thermally decompose because it has stronger metallic bonds that require more energy to break. These stronger bonds result in a higher activation energy needed for the decomposition process to occur. As a result, the reaction proceeds at a slower rate, leading to a longer decomposition time compared to less reactive metals with weaker metallic bonds.
What is the symbol used to show chemical change?
an arrow -> or sometimes a pair of arrows, one pointing to the right and another under it pointing to the left indicating that the change proceeds in both directions
Do chemical reactions contain the same number of moles as reaction proceeds?
Not necessarily. Some reactions do have the same number of moles, and some do not.Examples: NaCl + AgNO3 ==> NaNO3 + AgCl same # of moles N2 + 3H2 ==> 2NH3 different # of moles
Decomposition of hydrogen peroxide endothermic or exothermic?
It is obscenely exothermic This means that Hydrogen Peroxide is releasing heat to the surrounding environment, thus increasing the temperature.
What is the thermal decomposition of sodium carbonate?
The thermal decomposition of sodium carbonate is a chemical reaction according to the equation: Na2CO3 -> Na2O + CO2. The reaction is endothermic and therefore proceeds rapidly in the direction shown only in an environment from which ample heat energy can be absorbed.
What kind of chemical reaction is exothermic reaction?
An exothermic reaction is one that proceeds with the evolution of heat.
A graph plotting the energy change of a system as a chemical reaction proceeds is called what?
Energy diagram.
Is Entrophy change in a system that undergoes a spontaneous process positive negative or zero?
Negative entropy is a process or chemical reaction proceeds spontaneously in the forward direction.Positive entropy is a process proceeds spontaneously in reverse.
What is a forward reaction?
A forward reaction is a chemical reaction that proceeds in the direction written in the chemical equation, from reactants to products. It is the process in which reactants are converted into products.
When a chemical reaction proceeds in both directions the reaction is?
When a chemical reaction proceeds in both directions, it is referred to as a reversible reaction. In a reversible reaction, reactants are converted into products, and products can also react to form reactants. This results in a dynamic equilibrium where the rates of the forward and reverse reactions are equal.
What is the significance of the reaction arrow in chemical reactions?
The reaction arrow in chemical reactions signifies the direction in which the reaction proceeds. It shows the transformation of reactants into products and indicates the flow of the reaction.
The arrow in a chemical reaction is?
The arrow is an indication for the sense of reaction.
Does chemical potential changes as reaction proceeds?
yes,as gibbs free energy depends on temp. ,its value for a fixed amount of a substance change,so chemical potential changes with reaction.
In the representation of a chemical reaction what does the arrow stand for?
The arrow in a chemical reaction represents the direction in which the reaction proceeds. It shows the transformation of reactants into products, indicating the direction of the reaction from left to right.
What is export proceeds?
meaning of export proceeds
