Polyurethane reaction with chlorine?
When polyurethane is exposed to chlorine, it can undergo a chemical reaction that can result in degradation of the material. This reaction can lead to discoloration, embrittlement, and reduced mechanical properties of the polyurethane. It is important to avoid exposing polyurethane to chlorine-containing substances to maintain its integrity and performance.
When is alkali silica reaction seen?
Alkali-silica reaction is seen in concrete structures where reactive silica from aggregates combines with alkalis in the cement, forming a gel that expands under moist conditions, leading to cracking and degradation of the concrete over time.
Do copper and steel react?
Copper and steel do not have a significant chemical reaction when combined. However, they can undergo galvanic corrosion when in contact with each other in the presence of an electrolyte, leading to degradation of the metals over time.
Is roasting marshmallows a chemical reaction?
Yes, roasting marshmallows is a chemical reaction. When marshmallows are subjected to heat during roasting, the sugars and proteins they contain undergo a chemical reaction called Maillard browning. This reaction causes the marshmallows to change color, texture, and flavor.
What does status degradation mean?
Status degradation refers to a decline in one's social, professional, or personal standing. It can occur due to various factors such as a loss of reputation, a decrease in authority, or a lapse in performance. Status degradation can have negative effects on relationships, opportunities, and self-esteem.
What type of reaction occurs when an cooks in a pan?
This is a thermal degradation reaction.
What is hydrolyzing a chemical?
This is the degradation of a substance after the reaction with water.
What is Smith degradation?
it is reaction used to determine the position of linkage of the poly saccharide
What does synthesiser mean?
synthisised means a build up in a reactoin . E.G a degradation reaction is a break down in a reacrion . a synthsised reaction is a build up in a reaction .
What synthesiser mean?
synthisised means a build up in a reactoin . E.G a degradation reaction is a break down in a reacrion . a synthsised reaction is a build up in a reaction .
What is a degradation?
A degradation reaction breaks down a large molecule into smaller molecules. For example, the enzyme catalase breaks down Hydrogen Peroxide into Oxygen and Water.
What would the chemical reaction of a substance on heating?
This reaction is called thermal decomposition or thermal degradation; example: CaCO3 = CaO + CO2
Why when adding catalase to sucrose not makes it bubble?
Catalase is an enzyme that is substrate-specific, meaning that it has a particular reaction that it will catalyze (to speed up a reaction). Hydrogen peroxide (H2O2) is the specific substrate reactant with which catalase will react (in a degradation reaction). This is the degradation (breaking down of) reaction. 2H2O2 yields 2H2O+O2 O2 is oxygen which is indicated by the rising of bubbles upon reaction between the hydrogen peroxide and the catalase. Sucrose is not the specific substrate assigned to the catalase enzyme, therefore they will not react together in a degradation reaction, hence the lack of oxygen release (lack of bubbles). I hope this was helpful to you. God bless and Jesus loves you.
What is the effect of vinegar on aluminum?
When vinegar comes into contact with aluminum, it can cause a chemical reaction that results in the formation of hydrogen gas and aluminum acetate. This reaction can lead to the corrosion and degradation of the aluminum surface over time.
What does corrison mean?
Corrosion is the deterioration of a material, usually a metal, due to a chemical reaction with its environment. This can lead to rusting, tarnishing, or other forms of degradation.
What type of reaction occurs when an egg cooks in a pan?
The cooking of an egg in a pan is a chemical reaction called denaturation. The heat causes the proteins in the egg to change shape, unfold, and form new bonds with each other, resulting in a solidified structure.
How degradation study will carryout?
