Boiling water does not separate hydrogen from oxygen; it merely converts water (H₂O) from liquid to gas through the process of vaporization. The bubbles you see in boiling water are primarily water vapor, which is water in its gaseous form. These bubbles form when water reaches its boiling point, causing it to turn into steam. The molecular structure of water remains intact during boiling.
What else can I help you with?
When electrodes are immersed in water and electricity is passed then the bubbles formed on the negative terminal is?
When electrodes are immersed in water and electricity is passed, the bubbles formed on the negative terminal are primarily hydrogen gas. This occurs due to the process of electrolysis, where water (H₂O) is split into hydrogen ions (H⁺) and hydroxide ions (OH⁻). At the cathode (negative terminal), hydrogen ions gain electrons and are reduced to form hydrogen gas, which appears as bubbles. Conversely, oxygen gas is produced at the positive terminal.
Does water or potassium sulfide have the higher boiling point?
Potassium sulfide (K₂S) has a higher boiling point than water (H₂O). While water has strong hydrogen bonding that contributes to its boiling point of 100°C, potassium sulfide is an ionic compound with strong electrostatic forces between its ions, resulting in a much higher boiling point around 840°C. Thus, the ionic nature of potassium sulfide leads to a significantly higher boiling point compared to water.
Why does water have a significantly higher boiling point and than methane?
Water has stronger hydrogen bonds than Methane. More energy is required to break them, hence the difference in boiling point
Why are bubbles produced in a positive catalase test?
Bubbles are produced in a positive catalase test due to the breakdown of hydrogen peroxide (H₂O₂) into water (H₂O) and oxygen gas (O₂) by the enzyme catalase. When a catalase-positive organism is exposed to hydrogen peroxide, the catalase enzyme catalyzes this reaction rapidly, resulting in the release of oxygen gas, which forms visible bubbles. This reaction indicates the presence of catalase in the organism being tested.
Why boiling point of Chlorine is lower than boiling point of water?
The boiling point of chlorine is lower than that of water primarily due to the differences in molecular structure and intermolecular forces. Chlorine (Cl₂) is a diatomic molecule held together by relatively weak van der Waals (dispersion) forces, while water (H₂O) has strong hydrogen bonding between its molecules. These stronger hydrogen bonds in water require more energy to break, resulting in a higher boiling point. Thus, chlorine boils at a lower temperature compared to water.
What does the dissociation of water do?
You will find that it will separate into two ions:hydrogen (H+) and hydroxyl (OH-).
Rose blew h bubbles in two hours Which algebraic expression shows how many bubbles she blew in one minute?
h/120
How could you separate a mixture of H₂O and benzene?
One way to separate a mixture of water and benzene is through a process called distillation. Since benzene has a lower boiling point than water, the mixture can be heated to a temperature at which benzene evaporates but water remains a liquid. The vaporized benzene can then be collected and condensed back into a liquid form, effectively separating the two components.
What do acids in water separates into?
Strong acids: if its a strong acid, it will separate completely in water, meaning that the H+ ion concentration in the water will increase, which in turn causes the pH to decrease example: HCl -> H+ + Cl- Weak acids: weak acids don't separate completely in water, but because they are acids, they still separate. You can figure out how much of the acid has broken up by using a rice table and looking up the Ka. example: HCN <--> H+ + CN-
What do acids and water separate into?
Acids in water will (partially)split into ions: protons (H+) and anions (conjugate base ions.
What are the properties of water are due to what bonds?
Water's boiling point is very high for its size because of extensive network of H bonds.Freezing point is higher than expected because liquid water has only 15% more H-bonds than ice, making it easy to go from liquid to solid.Water has a high specific heat or heat capacity.Hydrogen bonds separate molecules as ice, making ice less dense than water, which means it floats

Why is there a difference in boiling points between h2o and h2s?
The difference in boiling points between water (H2O) and hydrogen sulfide (H2S) is primarily due to differences in molecular structure and intermolecular interactions. Water molecules form stronger hydrogen bonds compared to hydrogen sulfide molecules, leading to a higher boiling point for water. Additionally, water molecules are more polar compared to hydrogen sulfide molecules, which also contributes to the difference in boiling points.
Does salt affect the temperature of boiling water?
No, adding salt to water does not affect the temperature at which water boils. However, it does increase the boiling point slightly, so the water will need to be heated to a slightly higher temperature before it reaches its boiling point.

Why boiling point of H2O is higher then HF?
Both H2O and HF possess H bonds as their intermolecular force but H bonds of HF are stronger than that of H2o. therefore boiling point of than that of H2O. But experimental boiling point is high in H2O than that of Hf
