When a substance is added to water and bubbles form how can you confirm the type of change that took place?
When a substance is added to water and bubbles form, this often indicates a chemical change, especially if the bubbles are gas that was not present before, such as from a reaction. To confirm the type of change, one can observe if the original substances can be recovered or if new properties emerge, such as a change in color, temperature, or the formation of a precipitate. Conducting tests for gas composition (like using a lit splint to check for hydrogen) can further confirm a chemical change. If the substance can be separated back out unchanged, then it may be a physical change instead.
What else can I help you with?
Is it true that the properties of a substance change when it is added to a mixture?
yes.true
When acids are added to rocks containing a carbonate bubbles form is this evidence of a physical change or chemical change?
This is evidence of a chemical change. When acids react with carbonate minerals in rocks, they create gas (CO2), which leads to the formation of bubbles. This reaction results in the formation of new substances, indicating a chemical change.
When drain cleaner is added to water bubbles of hydrogen are produced Is what happens to form the bubbles when the cleaner is added a chemical or physical reaction?
If a gas is produced and it isn't a state change (such as steam bubbles forming), the reaction is a chemical change because the molecular makeup of either the water or the drain cleaner has changed and the hydrogen has been liberated.
What has to be added to a substance to cause a phase change?
Adding or removing energy in the form of heat is needed to cause a substance to undergo a phase change. This extra energy helps break the intermolecular forces holding the particles together in their current phase, allowing them to rearrange into a new phase with different properties.
What effect does an energy change have on the identity of a substance?
The identity of the substance reamain unchanged.
When sugar is added to tea does the substance change?
No
How will a substance change if energy is added to the liquid at 20 degrees Celsius?
The substance will get hawter
Is it true that the properties of a substance change when it is added to a mixture?
yes.true
What is the color of marigold flower indicator when acidic substance is added to it?
When an acidic substance is added to marigold flower indicator, the color generally turns red or pink. This color change indicates the presence of acidity in the substance being tested.
Can amount of each substance in a mixture cannot change?
The amount of each substance in a mixture can change if more of a substance is added or removed, causing the proportions of the substances in the mixture to change. However, the total amount of each substance in the mixture will remain constant.
Is a pane of clear glass a mechanical mixture or solution?
Solution
Which change in state requires that energy be added to the substance?
Melting solid into liquid requires energy to be added to the substance.

What state will most likely result if heat is added to a liquid?
It will change into a gas.Adding heat to or removing heat from a system may result in a temperature change and possibly a change of state. A liquid substance needs heat added to it in order to enter a gaseous state. If enough heat is added to a liquid substance it will change into a gas.

What substance that's added to acid has no visible change?
When an acid is mixed with water, there is usually no visible change, but the acid becomes less concentrated.
