What else can I help you with?
What of the following is not a potential sign of chemical change?
I wish I knew my dood
What are some following potential sign of chemical change?
Some signs are: change of the color, release of a gas, change of the temperature, formation of a precipitate, pH modification, viscosity variation, a change of the odor or taste, etc.
What is a sign that a chemical change has occurred smoke broken pieces change in shape or change in state?
The production of smoke from something burning would be a sign of a chemical change. Broken pieces, change in shape, or change in state are all physical changes.
Is the evaporation of water a potential sign of a chemical change?
No, evaporation causes a change in the state of matter (liquid to solid) which is a physical change
Is changing of color a sign of chemical change?
The change of color may be a sign of a chemical reaction.
Is the production of gas a potential sign of chemical change?
Depends on the gas. Producing acetylene (a gas used in welding) is a chemical change; producing steam (a gas used for many industrial purposes, as well as building heat) is a physical change.
Is a potential sign of chemical change a release in gas?
No. If a gas is dissolved under pressure, in a liquid then reducing the pressure will result in the release of a gas. This is what happens when you open a bottle or can of a carbonated soft drink.
Is it true that production of light is evidence that a physical change may have occurred?
Yes, the production of light can indicate that a physical change has occurred, but it's more commonly associated with chemical changes. In a physical change, light may be emitted due to phenomena like friction or the movement of particles. However, in chemical reactions, light often results from energy release as chemical bonds are formed or broken. Thus, while light production can be a sign of a change, it is not definitive for identifying whether that change is physical or chemical.
What is one sign of a chemical change?
Change of color
Do bubbles appear when a chemical change is happening?
Yes. They can. The clues of a chemical reaction are production of a gas, change in temperature, color change, production of a precipitate. If you take either baking soda or baking powder, and you add them to vinegar they both form bubbles in a chemical reaction.
What is one of the signs that a change is a chemical change?
One sign that a change is a chemical change is the production of gas, which may be observed as bubbles or odors. Other indicators can include a change in color, the formation of a precipitate, or a release or absorption of heat. These changes indicate that new substances are being formed, distinguishing chemical changes from physical changes.
Is evaporation a sign of chemcal change?
No, evaporation is a physical change and not a sign of a chemical change. Evaporation involves the change of a substance from a liquid to a gas without altering its chemical composition.
