Is milk rotting a physical or chemical reaction?
The process of milk rotting is a chemical reaction. It involves the breakdown of complex organic molecules in the milk by microorganisms, leading to the formation of new compounds that give off unpleasant odors and flavors.
Why did iodine stop turning blue-black?
Iodine turns blue-black when it comes in contact with starch because it forms a complex with the starch molecules. If iodine stopped turning blue-black, it could be due to the absence of starch, chemical interference with the reaction, expired iodine solution, or improper storage conditions affecting the reactivity of the iodine.
Is milk turning sour a physical or chemical change?
Milk turning sour is a chemical change. It occurs due to the fermentation of milk sugars by bacteria, leading to the production of lactic acid, which changes the taste and smell of the milk.
Potassium chlorate turns to oxygen gas is that chemical change or physical change?
The reaction of potassium chlorate turning into oxygen gas is a chemical change because the composition of the substance is altered, resulting in the formation of different molecules with different properties.
What is the difference between iodine solution and Benedict's solution?
Iodine solution is used to test for the presence of starch, turning blue-black in the presence of starch. Benedict's solution is used to test for reducing sugars such as glucose, turning from blue to brick red in the presence of reducing sugars.
How can you tell that a chemical reaction occurred from the copper sulfate?
You can tell that a chemical reaction occurred with copper sulfate if there is a visible color change in the solution, such as the solution turning blue or green. Additionally, if there is a formation of a solid precipitate, like copper hydroxide forming as a blue-green solid at the bottom of the solution, it indicates a chemical reaction has taken place.
Is turning a penny gold a chemical or physical reaction?
Turning a penny gold is a physical reaction rather than a chemical reaction. This process involves coating the penny with a layer of gold, which changes its appearance but does not alter the chemical composition of the penny itself.
Is something turning copper to green a chemical reaction?
ya mon.
Is turning cloudy a chemical change?
A solution turning cloudy is evidence of a chemical change.
Is turning an egg into a pancake a chemical or a physical reaction?
chemical -you cant turn the pancake back into an egg :)
Is banana's turning black a chemical reaction?
No, some people say that but it is not true!
Is An apple turning brown and food burning on stove is this a physical change?
An apple turning brown is a chemical change because it involves a reaction that changes the chemical composition of the apple. Food burning on the stove is also a chemical change as it involves a combustion reaction that changes the chemical composition of the food.
Can a solution produced through a chemical reaction?
Yes when you carry out any chemical reaction you will have some product at the end of the reaction. The things with which you start your chemical reaction is called reactants and the things which you get at the end are the products. For every chemical reation there is a product obtained and often catalyst are also used in it.
Is turning litmus paper red from blue a chemical change?
Yes, turning litmus paper red from blue is a chemical change because the color change results from a chemical reaction between the litmus paper and the substance it comes into contact with, indicating a change in the chemical composition of the paper.
What is a balanced word equation for the reaction of cucumbers turning into pickles?
A chemical reaction for this process doesn't exist.
Is rain turning to snow a chemical reaction?
No, rain turning to snow is a physical process, not a chemical reaction. It occurs when raindrops freeze as they fall through a layer of cold air near the Earth's surface, forming snowflakes.
Is a flower wilting and turning from white to brown an example of chemical reaction?
Yes, because some chemical reactions are involved.
