What is the fewest number of catalase molecules needed to break down 10 molecules of hydrogen peroxide?
Each catalase molecule can break down one molecule of hydrogen peroxide. Therefore, at least 10 catalase molecules would be needed to break down 10 molecules of hydrogen peroxide.
Which factors disrupt or break H bond?
I suppose that a high temperature can break a hydrogen bond.
In what temperature range does density of water increases with temperature?
Density of water in solid state i.e. ice increases from 0oC to 4oC, where it has maximum density.Ice has a cage-liked structure with lots of vacant spaces in between because of extensive hydrogen bonding between the water molecules. When the temperature increases, this structure collapses as the hydrogen bonding starts to break and as such the water molecules occupy the void spaces thereby increasing the density.Beyond 4oC, the ice melts completely.
Why DNA duplex melts at a specific temperature on heating?
DNA duplex strands are bonded by hydrogen bonds. On heating the hydrogen bonds break. At specific temperature called Tm half of the double helix is broken down (separated from each other) while the other half remains as such. This temperature can be determined , also the GC bond is stronger than AT so in such cases the temperature is more if the helix has more GC bonds.
When hydrogen bonds break what happens to energy?
When hydrogen bonds break, energy is absorbed from the surroundings to break the bonds. This results in a cooling effect as energy is used to separate the molecules. Conversely, when hydrogen bonds form, energy is released into the surroundings, leading to a warming effect.
Do hydrogen bonds have to break in order for water to increase in temperature?
a hydrogen bond is a weak interaction involving a hydrogen atom and fluorine, oxygen, or nitrogen atom...... there for it must form, not break because it is a weak interaction!
If all the hydrogen bonds in a DNA molecule were to break what would happen?
If all the hydrogen bonds in a DNA molecule were to break, the two strands of the DNA molecule would separate. This process is known as denaturation. The DNA molecule would no longer be able to function properly for processes such as replication or transcription.
What is the fewest number of catalase molecules needed to break down 10 molecules of hydrogen peroxide?
Each catalase molecule can break down one molecule of hydrogen peroxide. Therefore, at least 10 catalase molecules would be needed to break down 10 molecules of hydrogen peroxide.
Does hydrogen break easly?
No. hydrogen molecule has a strong single bond with a bond dissociation energy of 436 kJ/mol.
Which factors disrupt or break H bond?
I suppose that a high temperature can break a hydrogen bond.
What is the minimum energy required to break an HCl molecule into a hydrogen atom?
To break an HCl molecule into a hydrogen atom and a chlorine atom, the minimum energy required is equal to the bond dissociation energy of the H-Cl bond, which is approximately 432 kilojoules per mole.
How is a DNA molecule held together and separated by?
A DNA molecule is held together by its hydrogen bonds. The bonds are in between the bases of the molecule, for example cytosine and guanine. Because hydrogen bonds are weak, they are able to break apart easily and split when the molecule needs to be separated to bond with another DNA molecule for reproduction.

What effect does temperature have on hydrogen peroxide?
Hydrogen peroxide (H2O2) spontaneously degrades to water and oxygen according to the reaction: 2H2O2 ---> 2H2O + O2 As with any reaction, higher temperature increases the rate of the reaction. Specifically, higher temperature will accelerate the rate that H2O2 degrades.
The solubility of most solids as the temperature increases?
The solubility of most solids increases as temperature increases. This is because as temperature rises, the kinetic energy of molecules also increases, allowing solvent molecules to break apart solute molecules more easily. However, there are exceptions where solubility may decrease with temperature due to the dissolution process being endothermic.
Why water has a high boiling point compared with hydrogen sulfide a compound with a similar structure?
Water has a higher boiling point than hydrogen sulfide because water molecules are held together by stronger hydrogen bonds, compared to the weaker dispersion forces between hydrogen sulfide molecules. The presence of hydrogen bonding in water increases its intermolecular forces, requiring more energy input to break these bonds and raise the temperature to the boiling point.
What is the relationship between temp and solubility for kno3?
The solubility of KNO3 generally increases with temperature. As temperature increases, more kinetic energy is provided to the molecules, allowing them to break apart and dissolve more easily. This relationship is typical for many solid solutes in water.
