What is another term for chemical change?
A chemical change is also referred to as a chemical reaction. It typically involves the transformation of substances into new substances with different chemical compositions.
What tells the story of a chemical reaction?
The balanced chemical equation for a reaction tells the story of a chemical reaction by showing the reactants that are consumed and the products that are formed. It also provides information on the stoichiometry of the reaction, including the ratios of reactants and products involved.
Define chemical reaction and chemical equation?
A chemical reaction is a process that results in the transformation of chemical substances into new substances with different properties. A chemical equation represents this reaction using chemical formulas of the reactants and products, along with their respective coefficients to balance the equation.
Why crushing is done for a reactant before a chemical reaction?
the surface area of the particles are incresed so that the chemical reaction takes place fastly. for example if u have a granular sugar or powdered sugar what will be solved in water fastly surely the powdered form . bcoz of crushing surface area increses ! [ ENGR RIZI NFC IET MULTAN]
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
What will tell you the efficiency of a chemical reaction?
You need to calculate the yield of the reaction.
How can the efficiency of a chemical reaction be expressed?
A chemical reaction is represented by a chemical equation.
What is the catalytic efficiency formula used to calculate the effectiveness of a catalyst in a chemical reaction?
The catalytic efficiency formula is calculated by dividing the rate of the reaction with the catalyst by the rate of the reaction without the catalyst. This ratio helps determine how effective the catalyst is in speeding up the reaction.
How do you calculate the mass of an object in a chemical equation?
balance your chemical reaction equation then calculate moles, then calculate weight.
How does ethanol evaporation affect the efficiency of a chemical reaction?
Ethanol evaporation can affect the efficiency of a chemical reaction by changing the concentration of reactants and products in the reaction mixture. When ethanol evaporates, the volume of the reaction mixture decreases, leading to a higher concentration of the remaining components. This can potentially alter the reaction rate and equilibrium, impacting the overall efficiency of the reaction.
What is the method to calculate the reaction enthalpy for a chemical reaction?
The method to calculate the reaction enthalpy for a chemical reaction is to subtract the sum of the enthalpies of the reactants from the sum of the enthalpies of the products. This difference represents the overall energy change of the reaction.
How do you calculate the change in enthalpy for a chemical reaction?
To calculate the change in enthalpy for 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.
How do you calculate the reaction quotient in a chemical reaction?
To calculate the reaction quotient in a chemical reaction, you need to multiply the concentrations of the products raised to their respective coefficients, and then divide by the concentrations of the reactants raised to their respective coefficients. This helps determine if a reaction is at equilibrium or not.
Which variable is not required to calculate the Gibbs free-energy change for a chemical reaction?
The variable that is not required to calculate the Gibbs free-energy change for a chemical reaction is the temperature.
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.
How do you calculate the initial rate of reaction in a chemical reaction?
To calculate the initial rate of reaction in a chemical reaction, you measure the change in concentration of a reactant over a specific time interval at the beginning of the reaction. This change in concentration is then divided by the time interval to determine the initial rate of reaction.
How do you calculate the equilibrium constant for a chemical reaction?
To calculate the equilibrium constant for a chemical reaction, you divide the concentrations of the products by the concentrations of the reactants, each raised to the power of their respective coefficients in the balanced chemical equation. The resulting value represents the equilibrium constant for the reaction.
