What is indicated by formation of gas precipitate release of heat or a color change is?
The formation of gas indicates a chemical reaction producing a gas as a product. Precipitate formation shows the formation of a solid substance from a chemical reaction. Release of heat indicates an exothermic reaction, which releases energy in the form of heat. A color change is indicative of a chemical change where the substances involved absorb or emit light in different parts of the spectrum.
Is silicon a metal or noble gas?
Silicon is a metalloid, which means it has properties of both metals and nonmetals. It is not a noble gas.
What are indicators of a chemical change?
Things that can indicate a chemical change has occurred includeChange in colorRelease or absorption of energy (light, heat, etc.)Formation of gasFormation of precipitationIn chemical changes, the composition of the substance changes, and it is often difficult to reverse the process.
How do you obtain hydrogen gas from silicon and water?
Silicon (Si) doesn't react with water.
What is the noble gas configuration of silicon?
The noble gas configuration of silicon is [Ne] 3s^2 3p^2, where [Ne] represents the electron configuration of the noble gas neon. Silicon has 14 electrons, with two in the 3s orbital and two in the 3p orbital.
Can silicon be a gas?
Silicon is not a gas at standard temperature and pressure. It is a solid metalloid element that is commonly found in the Earth's crust. Silicon only exists as a gas at very high temperatures, around 2700°C.
Is silicon a gas at room temp?
No. Silicon is not a gas at room temperature. It is a solid.

The formation of gas indicates a chemical reaction producing a gas as a product. Precipitate formation shows the formation of a solid substance from a chemical reaction. Release of heat indicates an exothermic reaction, which releases energy in the form of heat. A color change is indicative of a chemical change where the substances involved absorb or emit light in different parts of the spectrum.
What are the four clues to a chemical reaction?
heat is produced, light is produced, gas is produced, the chemicals change color.
What type of gas is silicon?
Silicon is not a gas at all. In its elemental form it is a crystalline solid.
Is silicon a metal or noble gas?
Silicon is a metalloid, which means it has properties of both metals and nonmetals. It is not a noble gas.
Silicon has a relatively large latent heat of vaporization of 12800 Jg. This indicates that silicon has?
a high energy requirement to vaporize. The latent heat of vaporization measures the amount of energy needed to transform a substance from liquid to gas at its boiling point. In the case of silicon, the high value suggests strong intermolecular forces holding the silicon atoms together in its solid state.
How do you neutralize sulfuric acid without any gas or heat formation?
You cannot neutralize sulfuric acid without producing some heat. Adding it to a base that does not react to form a gas (such as sodium hydroxide) will prevent the formation of gas. Using dilute solution will produce a smaller temperature increase than concentrated solutions.
What is the purpose of argon gas in single silicon ingot?
Argon is used as a protective gas in the process of preparation of silicon crystals.
Does silicon reacts vigorously with fluorine?
Yes, silicon reacts vigorously with fluorine to form silicon tetrafluoride. This reaction can be highly exothermic due to the strong bond formation between silicon and fluorine atoms.
What are indicators of a chemical change?
