Is mold a chemical change?
No, mold growth is a biological process that involves the decomposition of organic matter by fungi. It is not a chemical change because the molecular structure of the substances involved remains the same.
How can you be sure that at least one chemical change has occurred?
You can be sure that a chemical change has occurred if there is a change in color, formation of a precipitate, evolution of gas, or absorption/release of heat during the reaction. These are all indicative of a chemical reaction where the substances are transformed into different compounds with new chemical properties.
Is wood rotting a chemical change?
Yes, wood rotting is a chemical change. It involves the breakdown of the wood's structure by fungi or bacteria, which changes the chemical composition of the wood through processes like hydrolysis and oxidation.
What is the least reliable physical property for identifying minerals?
Color is the least reliable physical property for identifying minerals because many minerals can have the same color but different compositions.
What are not clues that a chemical reaction has taken place?
Phase changes are one example of a non chemical change. If the substance reacts the same way chemically, it has the same properties such as melting point, there has not been a chemical change.
Is color he least reliable indicator of a chemical change?
No, the least reliable indicator of a chemical change is shape. Change of shape usually indicates a physical change, unless the material change resulted from a recombination or decomposition of the material's chemical form, as in the rotting of vegetable matter.
What assessment finding is the least reliable indicator of fluid status in an 80-year-old person?
Skin turgor in geriatric clients is not a reliable indicator of fluid status, because as people age the skin normally loses its elasticity.
What has to happen for a chemical change to happen?
At least 2 of the reactants must change their chemical formula.
What happens in any kind of chemical reaction?
At least one change in chemical bonding.
What is the least reliable mineral identification property?
Color is generally considered the least reliable mineral identification property because many minerals can have a variety of colors due to impurities or variations in chemical composition.
Which internet domain is the least reliable?
Which internet domain is the least reliable
Is light a physical property ora chemical change?
It is a physical change at least that is what I've been told
Is mold a chemical change?
No, mold growth is a biological process that involves the decomposition of organic matter by fungi. It is not a chemical change because the molecular structure of the substances involved remains the same.
Must a new substance be formed when you observe a chemical propery?
The formation of a new substance is the criterion for a chemical change. You can't have a chemical change without the formation of at least one new substance. As you can't observe a chemical property without setting a chemical change in motion, the answer to your question is yes.
Which mineral property is the least reliable for identifying a mineral?
Color is the least reliable property for identifying a mineral because many minerals can have the same color but different compositions.
How is nuclear change differ from normal chemical change?
Nuclear change usually (but not always) changes the element of an atom itself; at the very least, it changes the isotope of the atom, altering its radiological properties (such as its half life). A chemical change means a change to a molecule in which the atom is bound.
Is spray painting a car a physical change or chemical change?
Both, strangely enough. Applying the paint to the car is a physical change. The paint is a polyurethane compound. When you get it, it's in at least two containers - the paint, and a hardener. Stir them together and they undergo a chemical change.
