LaoBarium peroxide is commonly used to prepare hydrogen peroxide because it readily decomposes in the presence of water, releasing oxygen gas which then reacts with hydrogen to produce hydrogen peroxide. This method provides a simple and efficient way to produce hydrogen peroxide on a small scale.

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.
