What is indicated by formation of gas precipitate release of heat or a color change is?
chemical change
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.
Is silicon a metal or noble gas?
its a noble gas.
What is the noble gas configuration of silicon?
The electron configurartion of silicon is [Ne]3s23p2.
How do you obtain hydrogen gas from silicon and water?
Silicon (Si) doesn't react with water.
Can silicon be a gas?
Sure, you just need to heat or pressurize it sufficiently. At 1 atm of pressure, elemental silicon boils at 2,357 degrees Celsius. At room temperature, though, silicon is solid.
What is indicated by formation of gas precipitate release of heat or a color change is?
chemical change
Is heat a factor of a fossil fuel?
Yes, heat is a factor in the formation of fossil fuels (coal, oil and natural gas).
Is cloud formation endothermic or exothermic?
Cloud formation is an exothermic process because heat energy must be released to change a gas to a liquid.
Is silicon a gas at room temp?
No. Silicon is not a gas at room temperature. It is a solid.
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 soild liguid or gas?
Silicon is a solid.
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.
Is silicon a solidliquid or gas?
Silicon is a solid at room temperature.
What are the uses of silicon tetrachloride?
