Is heating red lead in a test tube a chemical change?
Just heating it is a physical change, but the heat soon produces a decomposition, which is a chemical change.2Pb3O4 --> 6PbO + O2
Is heated sulfur and iron fillings is substance or mixtures?
Heating sulfur with iron fillings lead to the formation of iron sulfide - a chemical compound.
Is heating potassium bicarbonate a chemical or physical change?
The heating itself is a physical change, a chemical change might come from the heating, however.
Is Heating potassium chlorate a chemical or physical change?
Heating anything to a visible change is ALWAYS a chemical change
Is heating sulfur a physical or chemical change?
Heating sulfur is a physical change. You're not changing the chemical composition of the sulfur, just the temperature. Now if you heat it to its boiling point and and it changes to a vapor it's a chemical change because you've changed its state of matter.(Actually changing the state of matter of an object is still a physical change, as it does not change the chemical composition of the element)
Heating a white substance produces a vapor and black material Was the substance an element or a compound?
compound as it decomposed into two separate things.

Can a compound be broken down into a simpler element?
This question is somewhat tricky: A compound can be broken down into at least two simpler types of matter, its constituent elements, by chemical means. However, a compound can not be broken down into a single simpler type of matter by chemical means, because that would require the annihilation of at least one of its constituent elements. Such annihilation could be achieved only by nuclear reactions.
If we mix carbon powder with sulfur powder are they still elements?
At the room temperature they remain elements in a mixure; by heating a compound is obtained, carbon disulfide.
What chemical compound forms when you heat Iodine?
Heating iodine sublimation occur: this is a direct change from solid to gas.
How do element differ than compound?
meaning of compound : combinations of two or more elements Compound (enclosure), a cluster of buildings having a shared purpose, usually inside a fence or wall Compound (fortification), a version of the above fortified with defensive structures Compound bow, a type of bow for archery Compound (linguistics), a word that consists of more than one radical element Compound (migrant labour), a hostel for migrant workers such as those historically connected with mines in South Africa Compound (music), an attribute of an interval or time signature Compounding, the mixing of drugs in pharmacy Polyhedral compound, a polyhedron composed of multiple polyhedra sharing the same centre element 1. elements The basic assumptions or principles of a subject. Chemical element, a building block in chemistry Electrical element, an abstract part of a circuit Heating element, a device that generates heat by electrical resistance Weather, sometimes referred to as "the elements"
How does a compound affect scientific experiments?
Compounds are chemically-combined elements. Very few elements exist in an uncombined state, so various physical or chemical reactions are needed to move elements from one state to another. Some physical operations include: Smelting (a heating operation) is used to remove metals from ore. Fractional distillation (vaporization and cooling) can separate mixtures of various compounds and elements.
Can elements be split up into simpler substances by heating them?
While some compounds do degenerate to their elements when heated, almost none do.
Is heated sulfur and iron fillings is substance or mixtures?
Heating sulfur with iron fillings lead to the formation of iron sulfide - a chemical compound.
Why heating enzymes usually produces a faster rate of reaction?
Why heating enzymes usually produces a faster rate of reaction?
Can chemical elements be split up by heating them?
Yes, it is possible: thermal decomposition and electrolysis.
Is heating potassium bicarbonate a chemical or physical change?
The heating itself is a physical change, a chemical change might come from the heating, however.
