The intermolecular forces that must be overcome to convert H2Se (hydrogen selenide) to gas are London dispersion forces and dipole-dipole interactions. These forces hold the H2Se molecules together in the liquid state. As energy is added to the system, these intermolecular forces weaken, allowing the molecules to overcome the attractive forces and transition into the gaseous state.
What else can I help you with?
How many valence electrons does H2Se have?
H2Se has six valence electrons. Each hydrogen contributes one valence electron, and selenium contributes four.
How many dots in the Lewis Dot Structure of H2Se?
There are 16 dots in the Lewis Dot Structure of H2Se. Each hydrogen atom contributes 1 dot and selenium contributes 6 dots.
Is hydrogen selenide polar?
Hydrogen selenide is a polar compound.
What chemical do you get mixing hydrogen and selenium?
Hydrogen selenide, with formula H2Se, is formed from reacting hydrogen and selenium.
What is the observation when hydrogen selenide is passed into lead(II)nitrate?
When hydrogen selenide (H2Se) is passed into lead(II) nitrate (Pb(NO3)2), a yellow precipitate of lead(II) selenide (PbSe) is formed. This reaction occurs due to the low solubility of lead(II) selenide in water. The overall reaction can be represented as: Pb(NO3)2 + H2Se → PbSe (s) + 2 HNO3. The formation of the yellow precipitate indicates the successful reaction between the two compounds.
What are the intermolecular forces for H2Se?
The intermolecular forces for H2Se are London dispersion forces, dipole-dipole interactions, and hydrogen bonding. Hydrogen bonding is the strongest among these forces due to the presence of hydrogen attached to a highly electronegative atom, such as selenium.
Why is the boiling point of H2O much higher than h2se?
The boiling point of a substance is influenced by the strength of intermolecular forces between its molecules. In the case of H2O (water), it forms strong hydrogen bonds between molecules, resulting in a higher boiling point compared to H2Se (hydrogen selenide), which has weaker dispersion forces due to larger atomic size and lower electronegativity of selenium.
What is the acid name H2Se?
H2Se is a stronger acid than H2S. The bond energy of H2Se is less than H2S, making it easier for the hydrogen atom to leave the molecule. Therefore, H2Se is expected to be a stronger acid than H2S.
What is the formula of the compound dihyrdogen selenide?
The correct formula is H2Se. Because it is an acid, hydrogen needs to be at the beginning. Hydrogen has an ionization of +1 and selenium (from which you get selenic) has -2, so you'll need 2 atoms of hydrogen (H) to balance out 1 atom of selenium (Se). So you'll have H2Se.
How many valence electrons does H2Se have?
H2Se has six valence electrons. Each hydrogen contributes one valence electron, and selenium contributes four.
Is H2Se a acid?
Yes, hydrogen selenide (H2Se) is an acid. It is a weak acid that dissociates in water to give off hydrogen ions.
Is H2Se an ionic bond?
No, as hydrogen-and selenium are both nonmetals the bonds are covalent.
How many dots in the Lewis Dot Structure of H2Se?
There are 16 dots in the Lewis Dot Structure of H2Se. Each hydrogen atom contributes 1 dot and selenium contributes 6 dots.
Why is the boilig point of water is higher than that H2S AND H2SE?
hydrogen bonding
Is hydrogen selenide polar?
Hydrogen selenide is a polar compound.
How many bonds can selenium have with hydrogen?
Hydrogen selenide (H2Se) has two bonds.
What is the formula of selenate?
The chemical formula for selenate ion is SeO4^2-.
