Atomic Structure
What is the smallest element?
What is Helium?
The molecular geometry of carbon dioxide.
What is linear?
The strongest type of intermolecular force.
What is Hydrogen Bonding?
This concentration unit is defined as moles of solute per liter of solution.
What is molarity?
According to the Brønsted–Lowry definition, an acid is a proton ____.
What is a donor?
This periodic trend generally decreases as you move from left to right across a period, due to the increasing effective nuclear charge
What is atomic radius?
A molecule with 3 bonding domains and 1 lone pair on the central atom has this electron-domain geometry.
What is tetrahedral?
This type of intermolecular force is present between all molecules and atoms, arising from temporary dipoles.
What are London dispersion forces?
When Qsp is greater than Ksp, the solution is supersaturated, and this process occurs.
What is precipitation?
This is the pH of a neutral aqueous solution at 25 °C.
What is 7?
The element with the highest electronegativity.
What is Flourine?
A bond between atoms with identical electronegativities.
What is a nonpolar covalent bond?
In paper chromatography, a substance that travels farthest up the paper has this type of relative attraction for the mobile phase.
What is a greater attraction?
The presence of a common ion in the solution decreases the solubility of the salt.
What is the common ion effect?
The pH of a 0.010 M solution of a strong monoprotic acid is this value.
What is 2.00?
The two elements that are liquid at room temperature (25 °C).
What are Bromine and Mercury?
The carbonate ion (CO₃²⁻) has a bond order of this value for each C–O bond
What is 4/3 or 1.33?
This property of a liquid, allowing insects to walk on water, results from cohesive forces due to hydrogen bonding.
What is surface tension?
A student dilutes a stock solution by a factor of 10, then dilutes the resulting solution by a factor of 5. The overall dilution factor of the final solution relative to the stock is this.
What is 50?
A solution that resists changes in pH upon addition of small amounts of acid or base.
What is a buffer?
The instrument used to separate ions by mass to charge ratio
What is a mass spectrometer?
The hybridization of the central atom in SF₆.
What is sp³d²?
The boiling point of H₂Te is higher than that of H₂Se largely because this type of intermolecular force becomes more significant with increasing molar mass.
What are London dispersion forces?
When 25.0 mL of 6.0 M HCl is diluted to a final volume of 500.0 mL, the new molarity is this.
What is 0.30 M?
This equation, pH = pKₐ + log([A⁻]/[HA]), is used to calculate the pH of a buffer solution.
What is the Henderson–Hasselbalch equation?
