Is producing carbon dioxide gas and solid lime by heating limestone is chemical change?
Yes, producing carbon dioxide gas and solid lime by heating limestone is a chemical change. This process involves the decomposition of limestone (CaCO3) into calcium oxide (CaO) and carbon dioxide (CO2) through the application of heat, which is a chemical reaction.
What is indicated by formation of gas precipitate release of heat or a color change is?
The formation of gas indicates a chemical reaction producing a gas as a product. Precipitate formation shows the formation of a solid substance from a chemical reaction. Release of heat indicates an exothermic reaction, which releases energy in the form of heat. A color change is indicative of a chemical change where the substances involved absorb or emit light in different parts of the spectrum.
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.
A piece of solid gold that changes from a solid to a liquid is a physical or chemical change?
The change from solid gold to liquid gold is a physical change because it does not alter the chemical composition of the gold. The transition from solid to liquid is a result of a change in temperature and does not involve any chemical reactions.
Is the formation of a solid a chemical change?
Yes, if it occurs as the result of a chemical reaction. For example, if two clear colorless solutions form a white precipitate (solid) when mixed, that would be an example of a chemical change. The formation of a solid from freezing is a physical change.
Why is fizzing and foaming a physical and chemical change?
When something fizzes and foams, it's producing some sort of gas within it, thus it's going from a solid/liquid to a gas (a physical change). But, this gas is likely not the same material that it came from. it's just a byproduct of a chemical reaction with in it (a chemical change).
Is changing of a solid to liquid chemical or physical change?
No it is a chemical
Is smoking a cigarette a physical or chemical change?
Smoking a cigarette involves a combination of physical and chemical changes. The act of lighting the cigarette and burning the tobacco involves a chemical change, producing new substances. The process of inhaling and exhaling the smoke is a physical change as it involves a change in state (from solid to gas) without altering the chemical composition of the smoke.
What reactions shows a chemical change producing a solid?
2AgNO3(aq) + CaBr2(aq) 2AgBr(s) + Ca(NO3)2(aq) estion…
What do you call the chemical change of solid and gas?
The PHASE change of solid TO gas is called Sublimation.
