Ionic compounds are soluble. The more ionic, the more soluble, since the interaction between ions and solvent (usually water) is strong enough to break up the lattice. On the contrary, the less ionic, the lattice is harder to break since the solute-solvent interaction is not strong enough. ...
What is the phosphorus compound used in 'strike anywhere' matches. What is the chemical equation for the burning of this compound in air? Explain how to write an ionic formula when given an anion and a cation. Write formulas of following compounds: a. Phosphorus trihydride b. Barium brom...
The number of ions in a compound depends on the structure of the compound and the oxidation states of the elements within the compound. An element's oxidation state is the number of electrons that an atom possesses or lacks relative to the number of protons in its nucleus. This determines t...
Born -Haber cycle is used to examine reaction energies when a metal and a halogen combine to form an ionic compound. It can be used to calculate lattice enthalpy. It is known that the formation of an ionic bond depends on lattice enthalpy. ...
Is NCl3 an ionic compound? It is a chemical compound that contains nitrogen and three chloride atoms. Since the elements forming the compound, nitrogen and chlorine, are both non-metals, the compound is molecular. Thecompound is not ionicbecause ionic compounds are formed by the bonding between...
Qn 1.2. this is chemical change because atoms of an element have been broken down and used to join up the other compound. Breaking down of atoms and the joining with other atoms involve the consumption of energy and change in chemical state which is ... ...
Step 1: Write the symbol and charge: Al3+and O2-. Step 2: Use crisscross method: Al2O3. Step 3: Reduce to lowest ratio and leave out subscripts of 1: Al2O3. Formula of a Compound: Empirical Formula Example An empirical formula will give the simplest whole-number ratio of atoms in...
Write the electron configuration for a fluoride ion. How many unpaired electrons are in the fluorine atom? What ion is fluorine most likely to form? Is it a cation or an anion? How many valence electrons are in the outer shell of a Fluorine atom? How many electrons are in arsenic? A)...
What are the characteristics of an ionic bond? How to identify an ionic bond? What is a non-covalent interaction and how does it differ from a covalent interaction? Write the difference between ionic and covalent bonds. Describe ionic bonds ...
Why do hydrogen ions have to bond with hydroxide ions? Can't they bond with something else with the same valence electron need? If a proton and electron are removed, can the element itself change? How do you write a compound which contains calcium (Ca) ...
