Why's the boiling point of hydrogen sulfide slightly higher than hydrogen selenide?
Sulfur is not nearly as electronegative as oxygen so that hydrogen sulfide is not nearly as polar as water. Because of this, comparatively weak intermolecular forces exist for H2S and the melting and boiling points are much lower than they are in water.
What elements make up water vapor?
Water vapor is composed of water molecules in a gaseous state, with each molecule consisting of two hydrogen atoms and one oxygen atom (H2O). When liquid water evaporates or solid ice sublimates, it forms water vapor.
What are elements in acetone?
Carbon, hydrogen, and oxygen
Compare the densities of hydrogen oxygen and water?
Water is a compound and Hydrogen and Oxygen are elements. Elements are substances whose atoms all contain exactly the same number of protons. Water has a melting point over a hundred degrees above the boiling point of either Hydrogen or Oxygen. This is why water is mostly in its liquid form on earth's surface and Hydrogen and Oxygen are always found as gasses. Water is also one of the very few substances whose solid is less dense than its liquid. This is why ice floats.
How many hydrogen bonds does Oxygen have?
Oxygen doesn't have any hydrogen bonds. A hydrogen bond is when a hydrogen atom is bonded with an electronegative atom, such as oxygen. Oxygen all by itself does not have hydrogen bonded to it. It is simply written as 02.
Is the boiling point hydrogen or oxygen colder?
It is simply the water that freexes. Water is not simply a mixture if hydrogen and oxygen. The two elements are bound together to form water molecules. So it must be treated as its own substance. The behavior of water cannot be explained using the behavior of elemental hydrogen or oxygen. Its properties are different from its constituent elements.
Why is the boiling point of H2O higher than boiling point of H2S?
Because of hydrogen bonding. Oxygen, nitrogen, and fluorine have a high boiling point.
How is particular gas an element?
Examples are: oxygen, hydrogen, nitrogen, etc.
What property of water is the same after it evaporates?
The chemical structure of the molecules. 2 Hydrogen connected by one Oxygen
Does boiling decompose water?
No. Boiling water just changes the state of matter. From a liquid to a gas. still 2 hydrogen and still 1 oxygen
Why is the boiling point of water greater than hydrogen sulfide?
The boiling point of a substance is determined by the strength of the intermolecular forces between its molecules. Water molecules form stronger hydrogen bonds compared to hydrogen sulfide molecules, leading to a higher boiling point in water.
What is the difference between boiling water and decomposing water?
Boiling water is the process in which water reaches its boiling point and turns into vapor, while decomposing water involves breaking down water molecules (H2O) into its constituent elements, hydrogen and oxygen. Boiling water is a physical change, while decomposing water is a chemical change. Boiling water is reversible, while decomposing water is typically irreversible.
Why water different from its components?
Water is different from its components, hydrogen and oxygen, because they have different properties. Water has unique physical and chemical properties due to its molecular structure, which differs from that of hydrogen and oxygen molecules. The combination of hydrogen and oxygen atoms in water leads to the formation of hydrogen bonds, which gives water its high surface tension, boiling point, and specific heat capacity, among other characteristics.
Does water have a higher than expected boiling point because of hydrogen and oxygen forming a single covalent bond?
Water has a higher boiling point than would be expected for a covalent compound of that molecular weight, because the water molecule is highly polar, and forms what are known as coordinate covalent bonds between water molecules. The polarity of the water molecule is the result of its shape, not the result of the single covalent bond that exists between the oxygen atom and each of the two hydrogen atoms.
Can water be separated into hydrogen and oxygen by boil physical change or chemical change?
Water can be separated into hydrogen and oxygen through a chemical change called electrolysis, which uses an electric current to break apart the water molecules. Boiling water is a physical change that only changes the state of the water from liquid to gas, but it does not separate the water into its component elements.
Why is water formed when you mix hydrogen and oxygen gases?
Water is H2O. 2 hydrogen atoms and 1 oxygen atom. Water is not formed when you mix hydrogen and oxygen. An explosive mixture of hydrogen and oxygen is formed. When you burn hydrogen in oxygen, the resulting compound is water. When you boil water the result is steam, or water vapor. Boiling does NOT separate the hydrogen and oxygen. An electrical current is needed to separate the hydrogen and oxygen. CAUTION: Do NOT put salt in the water to speed up the electrolysis of water. It changes the products. instead of hydrogen and oxygen, you get hydrogen, chlorine (gas), and sodium hydroxide. The last two are very poisonous.
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.
