The temperature of a substance does not change whether it is an element or a compound, though some substances will react when heated. White powder is not any particular substance. There are many substances that can come in the form of a white powders, but the only one that is an element is phosphorus. All the rest are compounds, though some of those may break down into their base elements when heated.
What else can I help you with?
What white powder when heated produces a colourless gas and a black solid?
When heated, zinc oxide (white powder) decomposes into zinc vapor (colorless gas) and solid zinc suboxide (black solid).
What is formed when zinc is heated with sulfur?
When zinc is heated with sulfur, zinc sulfide is formed. This reaction produces a white/yellowish powder of zinc sulfide.
Is sulfur powder an element compound or mixture?
Sulfur is an element.
What happens when copper sulphate crystal is heated?
When copper sulfate crystals are heated, they lose their water of hydration and turn into anhydrous copper sulfate, which is a white powder. The color change from blue to white signifies the removal of water molecules.
What element gives a green flame when it is heated?
Boron is the element that gives a green flame when it is heated.
What white powder when heated produces a colourless gas and a black solid?
When heated, zinc oxide (white powder) decomposes into zinc vapor (colorless gas) and solid zinc suboxide (black solid).
What is the chemical name for white powder when zinc in heated?
zinc(II) oxide
A white powder when heated produces a colourless gas and a black solid is the white powder a element?
It's a compound. If it was all one element it would all change the same way into the same thing. Since it's a compound, the molecules break up and the groups of atoms react differently to the heating (one becomes a gas, the other remains solid).
What is formed when zinc is heated with sulfur?
When zinc is heated with sulfur, zinc sulfide is formed. This reaction produces a white/yellowish powder of zinc sulfide.
Is sulfur powder an element compound or mixture?
Sulfur is an element.
What happens when copper sulphate crystal is heated?
When copper sulfate crystals are heated, they lose their water of hydration and turn into anhydrous copper sulfate, which is a white powder. The color change from blue to white signifies the removal of water molecules.
Isaiah is examining a white powder. Which test will demonstate that he is looking at a compound rather than an element?
During a chemical reaction, the powder breaks down into calcium and carbon.
Does an element melt when heated?
depends on the element
What is the white powder used in incandescent gas?
The white powder used in incandescent gas mantles is typically made of thorium dioxide. This powder is added to the fabric mantle to help it emit a bright white light when heated by the gas flame. However, due to health and environmental concerns, some manufacturers are moving towards using alternative materials.
What element gives a green flame when it is heated?
Boron is the element that gives a green flame when it is heated.
What do you call the white powder that is formed when magnesium reacts with steam?
The white powder formed when magnesium reacts with steam is magnesium oxide.
Who was So White?
