What type of bond is expected in the compound K20?
A compound with the formula K2O is potassium oxide. The bond expected in potassium oxide is ionic, as potassium (K) is a metal and oxygen (O) is a nonmetal. In an ionic bond, the metal atom (potassium) donates an electron to the nonmetal atom (oxygen) to form a positively charged cation (K+) and a negatively charged anion (O2-).
Why ionic bond is expected between magnesium and sulphur?
Ionic bond is expected between magnesium and sulfur because magnesium tends to lose two electrons to achieve a stable octet configuration, while sulfur tends to gain two electrons to complete its valence shell. This transfer of electrons from magnesium to sulfur results in the formation of an ionic bond between them.
What is the chemical equation when one mixes Ferric Chloride FeCl3 and Iron Fe?
When ferric chloride (FeCl3) is mixed with iron (Fe), the iron displaces the chloride ion to form ferrous chloride (FeCl2) and iron chloride (FeCl3). The chemical equation is: FeCl3 + Fe -> FeCl2 + FeCl3.
Is KBr expected to be ionic or molecular?
KBr (Potassium Bromide) is a ionic compound because a metal (potassium) is bonded to a nonmetal (bromine)
Which simple ion would chlorine be expected to form?
Chlorine is expected to form a chloride ion with a charge of -1 by gaining one electron to achieve a full valence shell and attain a stable electronic configuration.
How would you predict that chlorocyclopropane will behave in each of the test?
In a combustion test, chlorocyclopropane is expected to burn to produce carbon dioxide, water, and hydrogen chloride gas. In a test with alcoholic silver nitrate, a white precipitate of silver chloride is likely to form. With aqueous sodium hydroxide, a white precipitate of silver oxide will likely form, and in a reaction with magnesium metal, hydrogen gas will be evolved with the formation of a white precipitate of magnesium chloride.
What are the properties expected of the chloride of magnesium?
It is an ionic and water soluble salt.
How would the results turn out if a student forgot to read the label on the jar carefully and put potassium chloride in the crucible instead of potassium chlorate?
If a student accidentally put potassium chloride instead of potassium chlorate in the crucible during a lab experiment, the results would likely not match the expected outcome. Potassium chloride does not release oxygen when heated like potassium chlorate does, so there would be no oxygen to react with the magnesium present in the crucible. This would impact the ability to achieve the desired chemical reaction and may lead to incorrect data or observations.
In states would potassium chloride (KCl) be expected to have the lowest entropy?
solid crystal
What may be expected to happen if it is cooled down sugar may a precipitate out gas bubbles may form and produce foam water may evaporate rapidly?
a precipitate will form
What is the formula of the ionic compound expected to form between the elements K and S?

Which ionic compound would be expected to have the highest lattice energy?
Lattice energy is influenced by the charges of the ions and the distance between them. Among ionic compounds, those with higher charges and smaller ionic radii typically exhibit higher lattice energies. For example, magnesium oxide (MgO) has a higher lattice energy than sodium chloride (NaCl) due to the +2 charge of magnesium compared to the +1 charge of sodium, as well as the smaller size of the Mg²⁺ ion compared to Na⁺. Thus, MgO would be expected to have the highest lattice energy among common ionic compounds.
