What else can I help you with?
What would be the effect of collecting larger fraction when carrying out a column?
Their would be an increased possibility of getting multiple compounds rather than the one compound you are looking for. Possibly cis or trans differentiation. Using smaller fractions increases the possibility of getting just on, expected compound.

What is ionic compound expected to form between the elements sulfur and barium?
The ionic compound expected to form between sulfur (S) and barium (Ba) is barium sulfide (BaS). Barium has a +2 charge, while sulfur has a -2 charge when they combine, resulting in a neutral compound.
What is the formula of the ionic compound expected to form between the elements S and Ba?
What is the formula of the ionic compound expected to form between the elements Ca and I?
Ca2+ + 2 I- --> CaI2
How is the melting point of an impure compound expected to change with recrystallization?
The melting point of an impure compound is expected to decrease with recrystallization. This is because impurities disrupt the crystal lattice structure, causing a broader melting point range. Recrystallization removes impurities, resulting in a purer compound with a higher melting point.
What is the expected formula of a compound formed from the ions M plus 3 and X 1?
Most likely, MX3
What is the expected formula between calcium and oxygen?
The expected formula between calcium and oxygen is CaO, which is calcium oxide. This compound is formed by the combination of one calcium atom with one oxygen atom.
What is the formula of the ionic compound expected to form between the elements F and Ca?
The ionic compound expected to form between fluorine (F) and calcium (Ca) is calcium fluoride, with the chemical formula CaF2. In this compound, calcium donates two electrons to each fluorine atom, resulting in the formation of Ca2+ and F- ions that combine in a 1:2 ratio to achieve a neutral overall charge.
What is the formula of the ionic compound expected to form between the elements Cl and Ba?
The ionic compound formed between Cl and Ba is expected to have the formula BaCl2. This is because barium typically forms ions with a 2+ charge (Ba2+), while chlorine typically forms ions with a 1- charge (Cl-). To balance the charges and achieve neutrality in the compound, two chlorine ions are needed for every barium ion.
Which compound would be expected to show intense IR absorption at 3300 cm?
A compound containing a hydroxyl group (-OH) would be expected to show an intense IR absorption at 3300 cm-1 due to the stretching vibration of the O-H bond. Examples of compounds with a hydroxyl group include alcohols and carboxylic acids.
What is the formula of the ionic compound expected to form between the elements Al and F?
AlF3. Aluminum trifluoride.
What is the name for compound FrF2?
The compound FrF2 is named francium difluoride. It consists of one francium (Fr) atom and two fluorine (F) atoms. Francium is an alkali metal, and this compound is expected to exhibit properties similar to other alkali metal fluorides, although it is highly radioactive and rare.
How is the melting of an impure compound expected to change with recrystallization?
During recrystallization, impurities are removed as the compound is dissolved and then slowly cooled to allow for the formation of pure crystals. As a result, the melting point of the compound should increase after recrystallization because the presence of impurities lowers the melting point of the compound.
