What else can I help you with?
What term do you use to indicate salt solution in water in a chemical reaction?
(aq) It means aqueous. Example: NaCl(aq)
What is an example of the formation of a precipitate?
Formation of a precipitate is evidence of a chemical reaction.
Salt water is an example of is it a mixture solution or a chemical reaction?
Salt water is an example of a mixture. It is a solution made up of salt dissolved in water, without undergoing a chemical reaction. The components of salt and water can be separated by physical means such as evaporation.
What is an indicator of a chemical reaction?
A visible change in color, formation of a precipitate, evolution of gas, or change in temperature are indicators of a chemical reaction. These changes typically signify that the chemical composition of the substances involved in the reaction has been altered.
Is souring milk an example of a chemical change?
Yes, souring milk is an example of a chemical change. The breakdown of lactose by bacteria into lactic acid changes the composition of the milk, resulting in a new substance with different properties.
What term do you use to indicate salt solution in water in a chemical reaction?
(aq) It means aqueous. Example: NaCl(aq)
What is dissolution an example of?
Dissolution is an example of a chemical reaction. This is the process through which a solute and solvent mix to form a solution.
What changes can you observe when cemical reactions occur?
It depends on the chemical reaction. For example when you burn something it is a chemical reaction, but that is way different than if you mix baking soda and vinegar which is also a chemical reaction. It changes the matter into a different chemical matter make up of that substance.
Different example of chemical change?
Examples of chemical changes: combustion, corrosion, fermentation, photochemical reaction, polymerization.
What is a condition that is observed and measured in an experiment?
One example of a condition that is observed and measured in an experiment is the temperature of a solution in a chemical reaction. Researchers can measure the temperature at different time points to investigate how it changes during the reaction, providing insights into the reaction kinetics and thermodynamics.
What is indication of a chemical reaction?
HEAT, Heat is the the number one indication of a reaction. Also, changes of state of matter and mass are also indicators of a chemical reaction. an example is when an iron fence rusts.
What is a non example of chemical changes?
non example of chemical change: one non example is ice. ice is NOT an example of chemical change.
What is an example of the formation of a precipitate?
Formation of a precipitate is evidence of a chemical reaction.
What is an example of a chemical reaction when a solid is produced?
NaCO3 + CaCl2 --> 2NaCl + CaCO3 (s) In the above reaction, calcium carbonate is precipitated as a solid from the aqueous solution.
Salt water is an example of is it a mixture solution or a chemical reaction?
Salt water is an example of a mixture. It is a solution made up of salt dissolved in water, without undergoing a chemical reaction. The components of salt and water can be separated by physical means such as evaporation.
What is an example of reversible chemical changes?
The classical example of a reversible chemical reaction is:2 NaCl + CaCO3 ↔ Na2CO3 + CaCl2
Is burning a physical Change changes?
It's an exothermic reaction (oppose to an endothermic reaction). It's combustible reaction, (this is an example of chemical reaction) where a substance must combine with oxygen to produce, heat and light; or Burn.
