What kind of a chemical reaction happens when hydrogen peroxide can break apart to form water and oxygen gas?
Hydrogen peroxide decomposes into water and oxygen gas through a decomposition reaction. This reaction is typically catalyzed by enzymes such as catalase, breaking down the hydrogen peroxide molecule into water and oxygen in a step-wise manner.
What would happen if platinum was added to hydrogen peroxide solution?
Platinum acts as a catalyst in the presence of hydrogen peroxide, accelerating the decomposition of hydrogen peroxide into water and oxygen gas. This reaction produces bubbles of oxygen gas, causing the solution to foam or fizz. The platinum itself does not react and remains unchanged at the end of the reaction.
What evidence was there that a chemical reaction was taking place in the decomposition of hydrogen peroxide?
Evidence of a chemical reaction in the decomposition of hydrogen peroxide includes the formation of oxygen gas bubbles, a change in temperature (exothermic reaction), and the color change of the solution. Additionally, the release of oxygen gas could be tested by using a glowing splint, which would reignite in the presence of oxygen.
Is 3 percent hydrogen peroxide a suspension?
No, 3% hydrogen peroxide is not a suspension. It is a solution where hydrogen peroxide is completely dissolved in water. A suspension would involve particles of hydrogen peroxide that are not fully dissolved and would settle over time.
Why is oxygen gas produced from the decomposition of H2O2 and not hydrogen gas?
Hydrogen has a much lower attraction for electrons than oxygen does (or in more technical terms, oxygen has a much higher electronegativity). So when hydrogen gives up an electron to oxygen, it creates a strong chemical bond (although not an ionic bond; hydrogen's electronegativity is too high for that). When hydrogen peroxide gives up excess oxygen, the hydrogen remains bonded to the remaining oxygen (since hydrogen peroxide becomes water, H2O). If instead the hydrogen peroxide were to give up hydrogen, you would lose the powerful bond between hydrogen and oxygen, and all you would get in exchange would be a much weaker bond between hydrogen atoms and other hydrogen atoms, in the diatomic hydrogen molecule. Chemical reactions move in the direction of the strongest available bonds.
What is the substrate of catalase?
A substrate is a substance in which an enzyme reacts. The substrate for catalase would be hydrogen peroxide otherwise known as H2O2.
What happens when manganese dioxide is added to hydrogen peroxide and why was manganese dioxide added to the test tube containing hydrogen peroxide?
When manganese dioxide is added to hydrogen peroxide, it acts as a catalyst, increasing the rate of the decomposition of hydrogen peroxide into water and oxygen gas. Manganese dioxide was added to the test tube containing hydrogen peroxide to catalyze the reaction and speed up the decomposition process.
What happened whe the glowing splint was inserted in then test tube containing hydrogen peroxide and manganese dioxide?
When a glowing splint is inserted into a test tube containing hydrogen peroxide and manganese dioxide, the glowing splint will reignite, displaying the catalytic decomposition of hydrogen peroxide into water and oxygen. The manganese dioxide acts as a catalyst in this reaction, speeding up the decomposition of hydrogen peroxide.
What kind of a chemical reaction happens when hydrogen peroxide can break apart to form water and oxygen gas?
Hydrogen peroxide decomposes into water and oxygen gas through a decomposition reaction. This reaction is typically catalyzed by enzymes such as catalase, breaking down the hydrogen peroxide molecule into water and oxygen in a step-wise manner.

This reaction produces bubbles of oxygen gas, causing the solution to foam or fizz. The platinum itself does not react and remains unchanged at the end of the reaction.
What would happen if water replace in catalase activity?
If water were to replace hydrogen peroxide in catalase activity, the catalase enzyme would not function as intended. Catalase specifically catalyzes the decomposition of hydrogen peroxide into water and oxygen, so substituting water would eliminate the substrate needed for the reaction. Consequently, the enzyme would be inactive, and the crucial protective role of catalase in breaking down harmful hydrogen peroxide would be compromised.
What evidence was there that a chemical reaction was taking place in the decomposition of hydrogen peroxide?
Evidence of a chemical reaction in the decomposition of hydrogen peroxide includes the formation of oxygen gas bubbles, a change in temperature (exothermic reaction), and the color change of the solution.

Is 3 percent hydrogen peroxide a suspension?
No, 3% hydrogen peroxide is not a suspension. It is a solution where hydrogen peroxide is completely dissolved in water. A suspension would involve particles of hydrogen peroxide that are not fully dissolved and would settle over time.
How would you abbreviate hydrogen peroxide?
H2O2
What percent of hydrogen in hydrogen peroxide?
The formula is H2O2 so in pure hydrogen peroxide it would be 50 mole %. As the molecular weight is 34 it would be 2/34 x 100 = 5.9 weight % (1 decimal place).
What is the formula for six molecules of hydrogen peroxide?
The chemical formula for hydrogen peroxide is H2O2. It consists of two hydrogen atoms and two oxygen atoms. When referring to "six molecules of hydrogen peroxide," it would be written as 6H2O2.
Does the liver break down hydrogen peroxide in the summer or winter?
The liver breaks down hydrogen peroxide throughout the year, regardless of the season. Hydrogen peroxide is broken down into oxygen and water by an enzyme called catalase, which is present in the liver.
