Which symbol can be used to indicate a chemical reaction?

Which symbol can be used to indicate a chemical reaction?

The symbol that can be used to indicate a chemical reaction that takes place in the presence of a catalyst is letter B: Pt. Platinum is the metal which is often used as a heterogeneous catalysts for several reactions. Catalyst lowers the activation barrier of reaction, thereby accelerating the reactions rates.

What type of reaction occurs when is silver nitrate solution is mixed with sodium chloride solution?

precipitation reaction

When solid NaCl is stirred into water which of the following is not true quizlet?

When solid NaCl is stirred into water, which of the following is NOT true? The NaCl will fail to dissociate. If you had an aqueous mixture that contained Ag+, K+, and Pb+2 cations, how many different solids could precipitate if a chloride solution was added?

When coefficients are added the type of compounds is changed in the chemical reaction?

-When coefficients are added the type of compounds is changed in the chemical reaction. -Coefficients are added to compounds to ensure both sides of the reaction have equal numbers of each atom. -Subscripts are multiplied by the coefficients to determine the number of atoms in a compound.

Which characteristic best describes a decomposition reaction?

A characteristic of a decomposition reaction is a one single reactant and two, or more, products.

Which reason best describes why metals are shiny?

Explanation: It is known that metals have free electrons. These free electrons when come in contact with light, vibrate or oscillate at their respective position. As a result, the electrons gain small amount of energy and when this energy is released the surface of metal shines.

Which statement best describes the property of metals?

Answer: The correct answer is A. Generally all the metals are hard except sodium and potassium are soft. They are malleable that means it can be molded into different shapes.

Which of the following best describes the metals?

• Answer : The correct option is, Malleable, shiny, and able to conduct heat or electricity.
• Explanation:
• Metals : Metals are the elements which can easily loose electrons and forms cations.
• Properties of metals :
• Non-metals : Non-metals are the elements which can easily gain electrons and form an anion.
