What is the percent of the atoms in the universe are hydrogen?
Roughly 75% of the atoms in the universe are hydrogen.
What two elements comprise almost 100 percent of the matter in the universe?
Hydrogen and helium comprise almost 98% of the matter in the universe. They were created during the Big Bang and are the most abundant elements in the universe.
Why if sucrose is 51.5 percent oxygen by mass and only 6.4 percent hydrogen by mass is there twice as many hydrogen atoms than oxygen atoms?
The molecular formula of sucrose is C₁₂H₂₂O₁₁. From this formula, we can see that there are 12 hydrogen atoms and 11 oxygen atoms in sucrose. Despite oxygen accounting for 51.5% of the mass and hydrogen only 6.4%, the ratio of hydrogen atoms to oxygen atoms is determined by the molecular formula, not the mass percentages.
What is sulfur atoms and hydrogen atoms?
Sulfur atoms are chemical elements with an atomic number of 16. They are commonly found in compounds like hydrogen sulfide and sulfuric acid. Hydrogen atoms are the simplest and most abundant atoms in the universe, with an atomic number of 1. They are commonly found in compounds like water and hydrocarbons.
What is the percent composition of hydrogen in hydrogen peroxide?
The percent composition of hydrogen in hydrogen peroxide (H2O2) is 5.94%. This means that hydrogen makes up approximately 5.94% of the total mass of hydrogen peroxide.
What is the percent of the atoms in the universe are hydrogen?
Roughly 75% of the atoms in the universe are hydrogen.
Do hydrogen and helium make up about 50 percent of the atoms in outer space?
Yes, hydrogen and helium make up about 98% of the atoms in outer space. These two elements are the most abundant in the universe due to their prevalence since the Big Bang.
What gas is the universe most visible of?
The most abundant gas in the universe is hydrogen. Hydrogen atoms make up about 75% of the universe's elemental mass.
What two elements comprise almost 100 percent of the matter in the universe?
Hydrogen and helium comprise almost 98% of the matter in the universe. They were created during the Big Bang and are the most abundant elements in the universe.
How old are the Hydrogen atoms that make up 63 percent of your body mass?
They are about as old as the universe. In other word they are over 13 billion years old.
Do Hydrogen and helium atoms make up fifty percent of atoms in outer space?
Hydrogen and helium make about 98% of the atoms in the solar system !
Why if sucrose is 51.5 percent oxygen by mass and only 6.4 percent hydrogen by mass is there twice as many hydrogen atoms than oxygen atoms?
The molecular formula of sucrose is C₁₂H₂₂O₁₁. From this formula, we can see that there are 12 hydrogen atoms and 11 oxygen atoms in sucrose. Despite oxygen accounting for 51.5% of the mass and hydrogen only 6.4%, the ratio of hydrogen atoms to oxygen atoms is determined by the molecular formula, not the mass percentages.
Are hydrogen atoms properties different in different galaxies?
No, Elements are the same everywhere in the Universe.
What element has formed the largest numbers of atoms?
The most common element in the universe is hydrogen.
What temperature did the Universe have when hydrogen and helium formed?
When hydrogen and helium atoms first formed in the universe, the temperature ranged from about 3000 to 4000 Kelvin. This temperature allowed protons and electrons to combine to form neutral hydrogen atoms, a process known as recombination. Subsequently, the universe became transparent to radiation for the first time.
What percent of the sun is made of hydrogen?
Water has 66.7% hydrogen according to atoms and 11.1% hydrogen according to weight.
Does sugar have hydrogen?
Yes, sugar contains hydrogen atoms. Sugar molecules consist of carbon, hydrogen, and oxygen atoms bonded together.
