What is the specific gravity of barium?
The specific gravity of barium is around 3.5. This means that barium is about 3.5 times denser than water.
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?
Magnesium was discovered first, in 1755 by Joseph Black. Barium was discovered later, in 1808 by Sir Humphry 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?
It means there is 20 times the normal concentration of hydrogen peroxide in the solution. For example, a 20-volume hydrogen peroxide solution contains 6% hydrogen peroxide, while a typical over-the-counter solution is around 3%. This higher concentration is typically used for industrial or specialized applications.
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?
The label should indicate the concentration of hydrogen peroxide, not volts. If it is labeled 10 volts, it is likely a labeling error as hydrogen peroxide concentrations are typically indicated as a percentage (e.g. 3% hydrogen peroxide).
What do you mean by 100 volume of hydrogen peroxide?
When referring to "100 volume" hydrogen peroxide, it means that the solution can release 100 times its volume in oxygen gas when it decomposes. This measurement is commonly used to indicate the strength or concentration of hydrogen peroxide solutions.
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?
It is generally recommended to use hydrogen peroxide at a concentration of 3% to 7% for teeth whitening. Higher concentrations can be damaging to the enamel and gums. Consult with a dentist before using hydrogen peroxide for teeth whitening to ensure it is safe and effective for your individual needs.
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 does not cure sexually transmitted diseases (STDs). STDs require medical diagnosis and treatment by a healthcare provider. It is important to seek medical advice for proper treatment of STDs.
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.
What is the specific gravity of barium?
The specific gravity of barium is around 3.5. This means that barium is about 3.5 times denser than water.
