It all has to do with catalase. Catalase is an enzyme and a biological catalyst in the decomposition of H2O2. When its fresh, catalase is still present in the liver. However, when the liver is boiled, the catalase enzyme is denatured (as it is a protein).
Yes, cold liver will react with hydrogen peroxide because liver contains enzymes that can catalyze the breakdown of hydrogen peroxide into water and oxygen gas. This reaction is commonly used in biology experiments to demonstrate enzyme activity.
Copper does not react with nitrogen under normal conditions. However, at very high temperatures and pressures, copper can react with nitrogen to form copper nitride.
Hydrogen can react with metals to form metal hydrides. This reaction can occur at high temperatures or under certain conditions, and it depends on the specific metal and its reactivity with hydrogen.
lead does not react with water or steam
Tin can not only react with citric acid, it can react with any acid.
Boiled liver reacts with hydrogen peroxide because liver contains enzymes called catalase, which catalyze the breakdown of hydrogen peroxide into oxygen gas and water. This reaction produces bubbles of oxygen gas, which is visible as a foamy reaction when hydrogen peroxide is added to boiled liver.
test it and find out
Macerated liver has been treated and processed in a way that destroys the enzymes responsible for catalyzing reactions with hydrogen peroxide. Without these enzymes, such as catalase, macerated liver does not exhibit the same reaction with hydrogen peroxide as fresh liver.
Magnesium. I believe Magnesium does not react to fresh water but salt water is very corrosive and will disolve the metal.
Tap water
Yes, cold liver will react with hydrogen peroxide because liver contains enzymes that can catalyze the breakdown of hydrogen peroxide into water and oxygen gas. This reaction is commonly used in biology experiments to demonstrate enzyme activity.
A fresh piece of lithium will react with oxygen in the air to form lithium oxide. This reaction is exothermic and can produce heat, light, and potentially even a fire.
By macerating the liver, you are increasing its surface area (SA) therefore, the enzyme catalase can break down the hydrogen peroxide at a much faster and easier rate.
the frozen liver reaction should have been slower than the liver at room temperature, as this is the optimal condition for the enzyme catalase. The reaction would occur at a slower rate when an enzyme is below its optimal condition so generally when an enzyme is in cold conditions it will function slower.

The liver does not react with hydrochloric acid and peroxide because the liver is mainly composed of proteins and fats, which are not easily broken down by these substances. The enzymes and properties that usually cause chemical reactions in the liver are denatured or deactivated by the acid and peroxide, resulting in no significant reaction.
