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.
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 does a drawing of polarity water and the bond polarities make a major contribution to the overall molecular polarity look?
The polarity is a vector quantity. The resultant of the polarity of bonds determines the polarity of the molecule. In CO2 there is polarity between the two C-O but the polarity is equal and opposite in direction so CO2 doesn't have polarity. If the polarity of bonds is not cancelled then the polarity remains in the molecule.
What is the relationship between bond polarity and molecular polarity?
The relationship between bond polarity and molecular polarity is that the overall polarity of a molecule is determined by the polarity of its individual bonds. If a molecule has polar bonds that are not symmetrical, the molecule will be polar overall. If a molecule has nonpolar bonds or symmetrical polar bonds that cancel each other out, the molecule will be nonpolar overall.
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.
How many bonds can selenium have with hydrogen?
Hydrogen selenide (H2Se) has two bonds.
Is hydrogen selenide polar?
Hydrogen selenide is a polar compound.
Why is the boilig point of water is higher than that H2S AND H2SE?
hydrogen bonding
Intermolecular forces that must be overcome to convert H2Se to gas?
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 is the formula of selenate?
The chemical formula for selenate ion is SeO4^2-.
What are two examples of polarity?
-- negative polarity -- positive polarity
