What is the difference between a carbonate residue and an impression?
A carbonate residue is a chemical deposit left behind by the reaction of a carbonate compound with an acid, resulting in the release of carbon dioxide gas. On the other hand, an impression refers to a negative imprint or mark left behind on a surface due to pressure or contact with an object. While carbonate residues are formed through a chemical process, impressions are physical marks created by pressure or contact.
Is ashes physical property or a chemical property?
Ash isn't a property of any sort. It is a form of matter containing a variety of substances each with its own set of physical and chemical properties.
Is turning cloudy a chemical change?
A solution turning cloudy is evidence of a chemical change.
What evidence of chemical change occur in iron rust?
The evidence of chemical reaction in the rusting of an iron nail is a color change. This is due to the formation of iron oxide, which is the reaction between iron and oxygen.
Which is a good absorber of carbon dioxide gas?
Any hydroxide will completely 'absorb' CO2 gas, but this is a chemical reaction (carbonate is formed), thus not a real absorption in physical sense.
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.
When sodium carbonate is crushed it is physical or chemical change?
It is only a physical change.
Is crushing of sodium carbonate chemical change?
No, crushing sodium carbonate does not produce a new chemical substance. Thus, crushing is an example of a physical change.
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 adding calcium chloride to sodium carbonate a physical change or a chemical change?
Adding calcium chloride to sodium carbonate would be a chemical change because it results in the formation of new substances (calcium carbonate and sodium chloride) with different chemical properties than the original reactants.
What is the difference between a carbonate residue and an impression?
A carbonate residue is a chemical deposit left behind by the reaction of a carbonate compound with an acid, resulting in the release of carbon dioxide gas. On the other hand, an impression refers to a negative imprint or mark left behind on a surface due to pressure or contact with an object. While carbonate residues are formed through a chemical process, impressions are physical marks created by pressure or contact.
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.
Why does water not have the same physical and chemical property then hydrogen and oxygen?
Because molecules have other chemical and physical properties than the containing atoms !
Is changing of calcium carbonate into carbon dioxide a chemical or physical change?
Well, when it's changed, is there any way to get the calcium carbonate back? Think of that when you want to know. Physical changes appearance. Chemical changes what its made of and its particles.
Is mixing copper sulfate and sodium carbonate - chemical or physical reaction?
Mixing copper sulfate and sodium carbonate would be considered a chemical reaction because a new substance is formed as a result of the reaction between the two compounds, resulting in the formation of copper carbonate and sodium sulfate.
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 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.
