Why it is necessary to mention physical states of reactants and products in thermochemical reaction by hess's law?
Hess's law is important to thermochemistry because it allows us to anticipate enthalpy changes of reactions that are too slow to realistically record, such as rusting or reactions that are too fast. Hess's law, stating that the enthalpy is the same regardless of the pathway, allows us to take known enthalpy values and substituting them in to find your target reaction's enthalpy change. Credentials: I almost have a high-school diploma :P, so don't quote me; u won't sound any smarter than I do. S14 ftw!
What else can I help you with?
Thermochemical equations are chemical equations that include the of the reaction.?
Termochemical reactions include the enthalpy of reactants and products.
How do you find coefficients in chemistry equations?
It is necessary to know the reactants, the products and the valences.
Is a physical reaction is a process that one or more reactants change into one or more products with different properties?
No, a physical reaction does not involve the change of reactants into products with different properties. Instead, it refers to a process where the physical state or appearance of a substance changes, such as melting, freezing, or dissolving, without altering its chemical composition. In contrast, a chemical reaction involves the transformation of reactants into products that have different properties.
What represents the correct way to write a chemical equation reactants ----- products products equals reactants reactants equals sum sum ---- reactants?
reactants -----> products is correct
What is difference between physical and chemical balance?
The difference is that chemical equilibrium is the equilibrium of products and reactants in a reaction while physical equilibrium is the equilibrium of the physical states of the same substance.
Why it is necessary to mention physical states of reactants and products in thermochemical equation?
Including the physical states of reactants and products in a thermochemical equation is important because it provides additional information about the conditions under which the reaction occurs. The physical state can impact the enthalpy change of the reaction, as different phases have different enthalpies of formation. It helps to ensure that the reaction is balanced and allows for a more accurate determination of the heat transferred in the reaction.
Thermochemical equations are chemical equations that include the of the reaction.?
Termochemical reactions include the enthalpy of reactants and products.
How do reactants and products and compar before and after a chemical reactgion?
The products have different physical and chemical properties than the reactants.
What is the difference between a thermochemical equation and a traditional chemical equation?
A thermochemical equation includes the enthalpy change of a reaction, whereas a traditional chemical equation only shows the reactants and products involved in a reaction without considering energy changes. Thermochemical equations provide information about the heat absorbed or released during a reaction, while traditional chemical equations focus on the chemical identities of the species involved.
How do you find coefficients in chemistry equations?
It is necessary to know the reactants, the products and the valences.
In a heterogeneous equilibrium system the reactants and products exist in what?
Different physical states
How is thermochemical equation different from a balanced chemical equation?
A thermochemical equation includes information about the energy changes associated with a chemical reaction, such as enthalpy changes. A balanced chemical equation shows the reactants and products involved in a chemical reaction in their correct proportions. While a balanced chemical equation gives the stoichiometry of the reaction, a thermochemical equation provides additional information about the heat flow during the reaction.
Is a physical reaction is a process that one or more reactants change into one or more products with different properties?
No, a physical reaction does not involve the change of reactants into products with different properties. Instead, it refers to a process where the physical state or appearance of a substance changes, such as melting, freezing, or dissolving, without altering its chemical composition. In contrast, a chemical reaction involves the transformation of reactants into products that have different properties.
1 Are the properties of reactants and products always the same or can they be different?
The properties of reactants and products can be different. During a chemical reaction, new substances are formed which may have different properties such as color, odor, and physical state compared to the reactants.
What represents the correct way to write a chemical equation reactants ----- products products equals reactants reactants equals sum sum ---- reactants?
reactants -----> products is correct
What would happen to the entropy in the reaction 203g 302g?
The increase in entropy will depend on the physical states of the reactants and products. If the reactants are solid and the products are gaseous, there will likely be an increase in entropy due to the increase in disorder. However, if both the reactants and products are in the same state, the change in entropy may be minimal.
How many reactants and products are presented in a double replacement reaction?
2 reactants and 2 products
