Write the symbols, with charges, for ions formed by calcium, magnesium, strontium, potassium, and sodium, as well as the ions chloride and nitride. Write formulas and names for the compounds you can make by pairing each of the cations with each of the anions. I will show you what I have so far. I just didn't know how to do cations and anions. I tried anions but don't know if they are right and maybe it needs to be a...

Calcium Fluoride Determine the number of calcium ions per unit cell. Determine the number of fluoride ions per unit cell. What is the empirical formula of calcium fluoride based on the relative number of each ion in the unit cells? Is the empirical formula determined from the lattice structure in agreement with the one predicted by the typical ion charges? Are the anions or cations arranged in one of the basic cubic unit cells (simple, body-centered, face-centered)?

1. The propellent used to help launch the space shuttle in the solid-fuel boosters attached to the vehicle is 1.1 million pounds of ammonium perchlorate and powdered aluminum. The reaction generating the energy to blast the orbitor into space is: 3 NH4ClO4(s) + 3 Al(s) ---> Al2O3(s) + AlCl3(s) + 3 NO(g) + 6 H2O(g) The energy generated results from oxidation-reduction chemistry. Write the symbol for the metallic element that is oxidized in the reaction. Write the symbol for the...

Aluminum ion in solution reacts with water to form aqueous hexaaguaaluminum ()ion. Write this reaction below, remember phases. Aluminum is more likely to form a hydrated complex than the other four ions remaining in solution, because of its relatively small size and high charge To separate the Group B2 ion, the solution first is made basic by adding ammonia. In the presence of this weak base the pH is adjusted to 9-10 and the group B ions form insoluble hydroxides....
