What is the chemical reaction between hydrogen peroxide and K2Cr2O7?
The chemical reaction between hydrogen peroxide (H2O2) and potassium dichromate (K2Cr2O7) in acidic medium produces chromium(III) sulfate (Cr2(SO4)3), water (H2O), and oxygen gas (O2). This reaction is used in the laboratory to test for the presence of alkenes due to the oxidizing properties of potassium dichromate.
What happens when you add zinc to hydrochloric acid using the pop test?
When zinc is added to hydrochloric acid, the reaction produces hydrogen gas. The "pop test" is a test for hydrogen gas, where a lighted match is extinguished with a "pop" sound when in contact with hydrogen gas. The presence of the "pop" sound indicates that hydrogen gas was produced in the reaction.
How can you tell if a chemical reaction is happening in a test tube?
You can identify a chemical reaction in a test tube by observing changes such as color shifts, the formation of a gas (bubbles), or the production of a precipitate (solid) that was not present before. Additionally, changes in temperature or the release of light can also indicate a reaction. If the substances mix and exhibit new properties, it’s a strong sign that a chemical reaction is occurring.
Why is it necessary to heat a test tube in order for a chemical reaction to occur?

Why is it that when iron is added to dilute acid the test tube turns hot?
Because there's a chemical reaction going on.
What simple test might be undertaken to check if a chemical reaction produces oxygen?
glowing splint ... if it relights then the chemical reaction produces oxygen.
If a reaction produces an insoluble salt what will you notice happening in the test tube?
If a reaction produces an insoluble salt, you will observe the formation of a cloudy or precipitate solution in the test tube. This indicates that a chemical reaction has occurred and a solid salt has been formed that is not soluble in the reaction mixture.
How can I test hydrogen peroxide at home?
To test hydrogen peroxide at home, you can use a simple chemical reaction with yeast. Mix hydrogen peroxide with yeast in a container and observe if it produces bubbles, which indicates the presence of hydrogen peroxide.
What is the complete chemical reaction for nitrate reduction test?

Is heating red lead in a test tube a chemical change?
Yes, heating red lead in a test tube is a chemical change. The process of heating causes the red lead to undergo a chemical reaction, leading to a change in its chemical composition. This change is irreversible.
What happens when man taste a diamond?
There is no chemical or physical reaction in this test.
What is pyrite acid reaction?
Pyrite acid reaction refers to the chemical reaction between pyrite (iron sulfide) and acid, typically hydrochloric acid. This reaction produces hydrogen sulfide gas, sulfur dioxide gas, and iron chloride as products. It is often used as a test to identify the presence of pyrite in mineral samples.

The indicator in a test tube change colour orange to yellow what process is it?
This change in color indicates a chemical reaction taking place in the test tube. The specific reaction that caused the color change would depend on the substances present in the test tube and their chemical properties.

How can one predict if a precipitate will form in a chemical reaction?
One can predict if a precipitate will form in a chemical reaction by looking at the solubility of the reactants. If the product of the reaction is insoluble in the solvent, a precipitate will likely form. This can be determined by consulting a solubility table or conducting a solubility test.
