What else can I help you with?
What do you a property of matter that retains its identity after a reaction?
A chemical property of matter that retains its identity after a reaction is called a "physical property." These properties include characteristics such as density, color, shape, and boiling point, which remain unchanged during a chemical reaction.
Is dissolving of sugar in water a chemical or phyical reaction?
Dissolution is usually considered a physical reaction, although weak chemical bonds between the solute and solvent may exist in the solution.
What are the spectator ions in the reaction 2KOH plus H2SO4 and gt2H2O plus K2SO4?
In the reaction 2KOH + H2SO4 -> 2H2O + K2SO4, the spectator ions are K+ and SO4^2-. These ions do not participate in the chemical reaction i.e., they remain unchanged before and after the reaction.
What are spector ions?
Spectator ions are ions that do not participate in a chemical reaction and remain unchanged before and after the reaction. They are often found in solution as part of ionic compounds and may be written explicitly in chemical equations to represent their presence without being involved in the actual reaction.
How does adding an inert gas affect the equilibrium of a chemical reaction?
Adding an inert gas to a chemical reaction at equilibrium does not affect the concentrations of the reactants and products. This is because inert gases do not participate in the reaction. The total pressure in the system may increase, but the equilibrium position and concentrations remain unchanged.
What are the two attributes of a catalyst?
A catalyst must change the rate of a chemical reaction. It must be unchanged at the end of the reaction.
A chemical reaction has not occurred if the products have?
The same chemical properties as the reactants.
Why is an enzyme unchanged in a chemical reaction?
Enzymes are very efficient catalysts for biochemical reactions. They do not undergo permanent changes and so remain unchanged at the end of the reaction.
Is mealting a chemical reaction?
No, melting is a physical change of state, the chemical properties and formula of the substance remain unchanged.
How are the words reactant product chemical reaction and catalyst related?
Reactants: the initial substances in a chemical reaction Products: the final substances in a chemical reaction Catalyst: a stimulator of a chemical reaction, not directly involved in the reaction, remain unchanged
Is it a chemical reaction when a substance changes its form?
The change of form in not a chemical process; it is only a physical change, the molecules remain unchanged.
Is it true that the amount of matter present appears to change during a chemical reaction?
The total mass remain unchanged.
Why is a lava lamp not a chemical change?
The chemical structures remain unchanged.
When water evaporates its chemical composition?
The chemical composition remain unchanged.
Do enzymes get used up in a reaction, or do they remain unchanged and available to catalyze multiple reactions?
Enzymes remain unchanged and available to catalyze multiple reactions. They are not used up in a reaction.
What do you a property of matter that retains its identity after a reaction?
A chemical property of matter that retains its identity after a reaction is called a "physical property." These properties include characteristics such as density, color, shape, and boiling point, which remain unchanged during a chemical reaction.
What will happen if there is no physical and chemical change?
The system remain unchanged.
