The fire is extinguished by these factors: removing fuel, removing oxygen, removing temperature, making burning zone very small (too low of energy to initiate reaction). Select what is happening in video.
The liquid in the beaker is Hydrochloric Acid. The one poured is the Silver Nitrate. Observations: Hydrochloric Acid: Slightly yellow, liquid Silver Nitrate: White, crystalline, sand-like, solid It became denser as soon as the silver nitrate comes in contact with silver nitrate.
STATION #:8 INITIAL APPEARANCE: A light brownish color liquid is in a tube. OBSERVATIONS: A white liquid is poured into the brownies liqud and the white liquid turns solid into the brown liquid… then the white hardish liquid is stirred and then the white liquid dissolves into the water and goes into the bottom TYPE OF CHANGE: formation of a precipitate CLUE:Chemical change
In a chemical reaction between silver nitrate (AgNO3) and hydrochloric acid (HCl), AgNO3 is typically the silver nitrate, and HCl is the hydrochloric acid. Here's the reaction that occurs when these two substances are mixed: AgNO3 (aq) + HCl (aq) → AgCl (s) + HNO3 (aq) In this equation: AgNO3 (aq): This represents silver nitrate dissolved in water (aqueous solution). HCl (aq): This represents hydrochloric acid dissolved in water (aqueous solution). AgCl (s): This represents silver chloride, which is a white solid that precipitates out of the solution when silver nitrate and hydrochloric acid react. HNO3 (aq): This represents nitric acid, which is formed as a result of the reaction. The reaction between AgNO3 and HCl is a double displacement reaction in which the silver ion (Ag⁺) from silver nitrate combines with the chloride ion (Cl⁻) from hydrochloric acid to form solid silver chloride (AgCl). Nitric acid (HNO3) is also produced as a byproduct of the reaction. Please note that this reaction is commonly used in chemical experiments and qualitative analysis to detect the presence of chloride ions in a solution, as the formation of white precipitate (AgCl) is a characteristic test for chloride ions. does this help
For those in chemistry here's the answer. Initial Appearance: Clear yellow tinted liquid in a clear tube. Observation: A clear white liquid is poured in the clear yellow tinted liquid, once other liquids make contact with each other the clear colored liquid poured in turns into a white dense milky substance. Type of Change: Chemical change. Evidence: The clear liquid touches the yellow liquid making the clear liquid turn into a dense milky substance.
Initial Appearance- brownish yellowish liquid in a glass Observation- The person adds something in it and it foams inside the liquid but don not overflow and does not rise Type of Change- chemical Clue- formed precipitate
