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 is meant of '. ' in chemical reaction?
The "." in a chemical reaction represents a phase boundary or a physical state change. It separates reactants from products, indicating a change in state, such as from solid to liquid or gas to aqueous.
Which is A change in size shape or state of matter?
a change in size, shape or the state of matter is a physical change. True for A+.
Name two products that are made through physical change?
Examples:- copper wire- wheat flour
What is oxygen's physical state?
oxygen's physical state is gas
Products must be in the same physical state as the reactants?
There is no question here - please restate and clarify if you would.
What tells reactants products physical state and proportions of each substance in a chemical reaction?
A chemical equation
What are the products of physical change?
The products of a physical change are the same as what you started out with because their have been no changes to its chemical properties. Ex: If you rip a piece of paper, it's still paper.
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.

What are the state symbols in a chemical equation?
State symbols in a chemical equation indicate the physical state of the reactants and products. Common state symbols include (s) for solid, (l) for liquid, (g) for gas, and (aq) for aqueous (dissolved in water).
Which is a characteristic of chemical equilibrium but not physical equilibrium?
Reversibility of reactions is a characteristic of chemical equilibrium but not physical equilibrium. In chemical equilibrium, the forward and reverse reactions continue to occur, while in physical equilibrium, there is no net change in the physical state of a substance.
Is the physical state a physical or a chemical?
it is a physical
Is melted ice is physical?
physical because its changing state. changes of state mean physical
What is a sentence with the word physical state?
the physical state is having problems.
What is new substances formed in a chemical reaction?
New substances formed in a chemical reaction are called products. These products have different chemical properties than the reactants that were originally present, and the reaction is often characterized by changes in physical properties such as color, temperature, or state.
State 5 products of petrelium and their uses?
state atleast 5 products of petruleum
