- The number of molecular orbitals formed is always equal to the number of atomic orbitals combine
- The more stable the bonding molecular orbital, the less stable the corresponding antibonding molecular orbital.
- In a stable molecule, the number of electrons in bonding molecular orbitals is always equal to that in antibonding molecular orbitals.
- Like an atomic orbital, each molecular orbital can accommodate up to two electrons with opposite spins in accordance with the Pauli exclusion principle.
- Cement containing no iron is white.
- Cement containing excess amount of lime cracks during setting.
- Setting of cement is an endothermic process.
- Setting of cement is an example of hydration.
- Molarity
- Temperature
- Density
- All are correct
- Quartz glass —>100% silica
- Pyrex glass—-> 60-80% silica, 10 to 25% B2O and Al2O3,
- Soda lime glass 80% silica, 20% CaO
- Soda lime glass—–> 75 silica, 15% Na2,O, 10% CaO
- The concept of hybridization is not applied to isolated atoms.
- Hybridization is the mixing of at least two non-equivalent atomic orbitals.
- The number of hybrid orbitals generated is more than the number of pure atomic orbitals that participate in the hybridization process.
- Hybridization requires an input of energy.
- density in kg m
- forge in Newtons
- pressure in pascals
- amount of the substance in mol L
- Reversible
- Increases with increase in temperature
- Low heat of adsorption
- Increases with increase in surface area
- On reaction with nitrous acid alkylamines produce alcohol
