How do you know that the reaction between a metal carbonate and acid is a chemical change?
The reaction between a metal carbonate and an acid is a chemical change because it results in the formation of new substances. For instance, when carbonates react with acids, they typically produce carbon dioxide gas, water, and a salt. Observable signs such as gas evolution, temperature changes, or color changes further indicate that a chemical transformation has occurred, as the original reactants can’t be recovered in their initial forms.
What else can I help you with?
When acids are added to rocks containing a carbonate bubbles form is this evidence of a physical change or chemical change?
This is evidence of a chemical change. When acids react with carbonate minerals in rocks, they create gas (CO2), which leads to the formation of bubbles. This reaction results in the formation of new substances, indicating a chemical change.
What must a occur for a change to be a chemical reaction?
The answer choices weren't provided. There must be a change in chemical properties for a change to be considered a chemical reaction.
What three ways would let you know that a reaction had taken place?
Changes in color: If the color of the reactants or products changes during the reaction, it is a sign that a chemical reaction has occurred. Formation of a gas: Production of gas bubbles or fizzing indicates a chemical reaction, such as in the reaction between an acid and a carbonate. Changes in temperature: If the reaction absorbs or releases heat, causing a change in temperature in the surroundings, it signals a chemical reaction has taken place.
What type of energy change associated with chemical reaction between magnesium and hydrochloric acid?
This reaction is exothermic.
Is Gas produced from a reaction is a phase change and not a chemical change.?
A gas released during a chemical reaction is a chemical change.
Copper sulfate and sodium carbonate physical or chemical change?
When copper sulfate and sodium carbonate are mixed together, a chemical reaction occurs. This reaction forms copper carbonate, a new substance with different properties than the reactants. Therefore, the mixing of copper sulfate and sodium carbonate is a chemical change.
When limestone fizzes when acid is added is physical or chemical change?
The fizzing of limestone when acid is added is a chemical change. This is because a chemical reaction occurs between the acid and the calcium carbonate in the limestone, resulting in the production of carbon dioxide gas.
Is a form of green carbonate when exposed to moist air a physical property or chemical property?
This is a chemical property. The reaction of green carbonate with moist air to form a different substance involves a change in the chemical composition of the substance, indicating a chemical reaction.
Is a sodium carbonate and copper sulfate mixture a chemical change?
No, mixing sodium carbonate and copper sulfate is a physical change as the substances retain their chemical identities. A chemical change would involve a reaction where new substances are formed.
How can you tell the difference between a chemical reaction and not a chemical reaction?
A chemical reaction will do the following; Change colour Create smoke A non chemical reaction (Physical Reaction) will do the following; Change State Be able to change back to the original materials

Is hydrochloric acid and calcium carbonate a first order reaction?
No, the reaction between hydrochloric acid and calcium carbonate is not a first order reaction. It is a decomposition reaction where the rate of reaction will not be constant as the concentration of the reactants change over time.
There is no in time between the action and the reaction?
chemical change
When adding sodium carbonate and hydrochloride acide is chemical change?
Yes, when sodium carbonate and hydrochloric acid are mixed, a chemical reaction occurs to form sodium chloride, water, and carbon dioxide. This is a chemical change as new substances are formed with different properties from the original reactants.
Why sodium carbonate is not a chemical change?
Sodium carbonate is a compound. Until you react it with something, it cant have or be a chemical change.
Is dissolving sodium carbonate a chemical change?
Dissolving sodium carbonate in water is a physical change, not a chemical change. This is because the chemical composition of sodium carbonate remains the same before and after dissolving.
