What is the specific gravity of barium?
what is the specific gravity,luster,transparency,streak,cleavage,and fracture of barium?
What is average life of barium?
99.79% of Barium is stable. The radioactive isotopes, 130Ba and 132 Ba have half lives of over 1.3*10^21 years. That is approx 280 billion times the age of planet earth! In the circumstances, it would be safe to say that barium is a stable element.
Which was discovered first Magnesium or Barium?
No, Iron was known to man since ancient times... but magnesium was discovered in 1808 by Sir Humphrey Davy.
How many times larger in the number of hydrogen atoms than oxygen atoms in all carbohydrates?
2 times larger
An atom of helium has a mass about four times greater than that of an atom of hydrogen Which choice makes the correct comparison of the relative numbers of helium and hydrogen atoms in equal masses o?
An equal mass of helium would contain fewer atoms compared to hydrogen, as each helium atom is four times heavier than a hydrogen atom. This is because the atomic mass of a helium atom is roughly four times that of a hydrogen atom.
What does 20 volumes hydrogen peroxide mean?
This means that for every volume of hydrogen peroxide used, 20 volumes of oxygen will be produced. For example, if 1 ml of hydrogen peroxide is used/decomposes, 20 ml of oxygen will be formed.
How often can a catalase molecule be used to hydrolyze hydrogen peroxide?
A catalase molecule can be used multiple times to hydrolyze hydrogen peroxide. It speeds up the reaction without being consumed in the process, allowing it to catalyze the decomposition of many molecules of hydrogen peroxide before being reused.
If a bottle of hydrogen peroxide is labeled 10 volts what does this indicates?
Volume is the amount of oxygen that is contained in a given amount of peroxide. For example, 3% hydrogen peroxide is V10 or 10 volume, because it will release 10 times it's volume in oxygen. One pint of 3% hydrogen peroxide will release 10 pints of oxygen as it breaks down. Gee, now there is something to think about. Of course, V20 will release twice as much oxygen, 20 times its volume.
What do you mean by 100 volume of hydrogen peroxide?
It means that the concentration of the peroxide is such that for every 1mL of hydrogen peroxide solution, 100mL of oxygen will be produced if fully reduced, catalyzed, exposed to light, heated or decomposed in any manner to the fullest extent. The fullest extent means the end point where every molecule of hydrogen peroxide releases one oxygen atom, and is converted into water.
How do you clean a sunbeam water cooler?
To clean a water cooler dispenser, remove all filters and run 35% food grade hydrogen peroxide diluted with 11 times as much water through the dispenser. It is necessary to use food grade hydrogen peroxide as it does not contain the harmful stabilizers contained in regular 3% hydrogen peroxide. The dilution step is necessary because otherwise the peroxide will be too caustic.
What are the differences between hypochlorous acid and hydrogen peroxide in terms of their effectiveness as disinfectants?
Hypochlorous acid is more effective as a disinfectant compared to hydrogen peroxide. This is because hypochlorous acid has stronger antimicrobial properties and can kill a wider range of pathogens, including bacteria, viruses, and fungi. Hydrogen peroxide is less effective and may require longer contact times to achieve the same level of disinfection.
What percentage can you use to whiten your teeth by using hydrogen peroxide?
Do Not Try To Whiten Your Teeth With Peroxide it will burn your whole mouth. Update by someone else: I have used 3% diluted with water at a ration of 1 part water to 1 part hydrogen peroxide. Then swished it around my mouth for a few minutes and the spat out. This week I have done this 4 times without any burning sensation.
How does hydrogen peroxide react with copper?
When hydrogen peroxide reacts with copper, it oxidizes the copper metal, leading to the formation of copper oxide (CuO) and water (H2O). This reaction can cause a fizzing or bubbling as the oxygen from the peroxide reacts with the copper surface. Over time, the copper metal may appear dull or oxidized due to this reaction.
How hydrogen gas is using in the airjet jackets?
A hydrogen peroxide-powered motor is based on the decomposition reaction of hydrogen peroxide. Nearly pure (90% in the Bell Rocket Belt) hydrogen peroxide is used. Pure hydrogen peroxide is relatively stable, but in contact with the catalyst (for example, silver) it decomposes into a mixture of superheated steam and oxygen in less than 1/10 millisecond increasing in volume 5000 times: 2 H2O2 → 2 H2O + O2. The reaction is exothermic, i.e. with liberation of much heat (about 2500 kJ/kg), forming in this case a steam-gas mixture at 740 °C. This hot gas is used exclusively as the reaction mass and is directly led to one or more jet nozzles.
Does hydrogen peroxide cure STDs?
No, hydrogen peroxide is not an effective treatment for STDs. A prescription med is necessary--exact med depends on the type of STD. in olden times an arsenic preparation known as salvarsan was used now we use antibiotics which are safer for obvious reasons. It depends on what the patient responds to and what they are allergic to, that decides treatment
Does hydrogen peroxide remove bloodstains?
Yes. You just have to pour it on the stain and let it dry. If it doesn't come out the first time, repeat the process as many times as needed. Then wash it.
