How does carbon dioxide change?
chemical because it is changing the state from solid to a gas in which is a chemical change
Why can't you separate carbon dioxide and get oxygen?
because there would have to be oxygen in the carbon dioxide to get the oxygen and carbon dioxide and oxygen put together make water because water is H2O(2 hydrogen and 1 oxygen)this answer is incorrect because there is oxygen in carbon dioxide or co2 ( one carbon two oxygen)The top answer is completely incorrect, there is oxygen in carbon (C) dioxide (O2). It is possible to separate the carbon from the oxygen, but it is very difficult. This is because it is a stable atom, meaning the last electron shell is full. It is possible to separate it, but not on a large scale.
Is scrubbing the floor a physical or chemical change?
It is a physical change.
Does plants change carbon monoxide to carbon dioxide?
plants do not change carbon monoxide into carbon dioxide. they, on the other hand, convert carbon dioxide in to oxygen.
Is melting copper an example of chemical change?
It can be. Temperature increases usually induce physical changes in the broad sense. If the change in temperature merely induces a state change (for instance, the copper is melted - becoming a liquid) then it is purely a physical change. Presuming that heating will occur in the presence of air, it will also increase the rate of oxidation and, therefore, be indirectly inducing a chemical change.
Is using oxygen to separate molten copper sulfide into copper sulfur dioxide a physical change?
no it is a chemical change
When Hydrogen sulfide is boiling is it a chemical or physical change?
It is a physical change. This is so because no new substance is formed. Hydrogen Sulfide is Hydrogen Sulfide wether it is boiling, at room temperature, or freezing.
Is freezing carbon dioxide a chemical change or physical change?
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
Is tarnish of silver a physical or chemical change?
The tarnishing of silver is due to a reaction with hydrogen sulfide. Because the end result of the tarnish is silver sulfide, it is a chemical change.
Is separate is a physical or chemical change?
when you separate a substance from a mixture, it's a physical change... Technically, you can get it back in the mixture.
Is tarnish of silver physical or chemical change?
The tarnishing of silver is due to a reaction with hydrogen sulfide. Because the end result of the tarnish is silver sulfide, it is a chemical change.
What is the sublimation of carbon dioxide a chemical property or chemical change?
It is a change in physical state, which is a physical change.
Is silver tarnishing a physical change?
No, it is a chemical change. The tarnish seen on silver is silver sulfide which formed by the silver reacting from small amounts of hydrogen sulfide in the air. So silver sulfide has been created by a chemical reaction.
Are physical and chemical change different?
Physical change does not produce a new substance. Chemical change produces a new substanceIn a chemical change the atoms/molecules are chemically joined together so they are very hard to separate. were as they are easyer to separate in a physical change
Why is a silver platter tarnishing a physical property?
Silver platter tarnishing is a chemical change: a reaction with hydrogen sulfide.
Is combining carbon dioxide and water to make sugar a physical change?
Combining carbon dioxide and water is a chemical change, not a physical change, but it doesn't make sugar. Carbon dioxide and water makes carbonic acid. CO2 + H2O <--> H2CO3-->H+ + HCO3-
When carbon dioxide comes from the fuel of the car is it a physical or chemical change?
chemical change
