This term describes atoms of the same element with the same number of protons but different numbers of neutrons.
What are isotopes?
This trend decreases across a period but increases down a group in the Periodic Table.
What is atomic radius?
This law states that the total enthalpy change for a reaction is independent of the route taken.
What is Hess’s Law?
These are the two products of a complete combustion reaction of any hydrocarbon.
What are carbon dioxide ($CO_2$) and water ($H_2O$)?
This type of error affects the precision of results and can be reduced by repeating experiments.
What is random error?
According to VSEPR theory, this is the electron domain geometry and the specific molecular geometry of $SF_6$.
What is octahedral?
This is the equation representing the first ionization energy of Magnesium.
What is... (correct equation)?
In an exothermic reaction, this is the sign of delta H and the relative stability of the products compared to the reactants.
What is negative Delta H < 0 and products are more stable?
This is the name of the functional group found in CH3COCH3 (propanone).
What is a carbonyl group (or ketone)?
This is the number of absolute uncertainty of a balance that can record the measurement 0.0505.
What is +/- 0.0001g?
This specific type of bond forms when both electrons in the shared pair originate from the same atom, often seen in the ammonium ion ($NH_4^+$).
What is a coordinate covalent bond (or dative bond)?
These transition metal complexes are colored because of the splitting of this specific subshell when ligands approach the central metal ion.
What is the d-subshell (or d-orbitals)?
This is the unit for the rate constant k in a second-order reaction.
What is dm^3 mol^-1 s^-1?
This type of reaction mechanism occurs when 2-chloro-2-methylpropane reacts with warm dilute NaOH, involving a carbocation intermediate.
What is SN1(Nucleophilic Substitution Unimolecular)?
This analytical technique uses electromagnetic radiation to cause transitions between nuclear spin states, helping determine the structure of organic molecules.
What is HNMR spectroscopy?
