Write the chemical formula for each compound described. calcium chloride (1 Ca ion, 2 Cl ions): sodium sulfide (2 Na io...
Study Exercise 1 Name Write the formula for each ion on the line below en compound formed by the combination of the ions. ion on the line below each name, then fill in the blanks with the correct formula and name of the Chloride Hydroxide Nitrate Sulfide Sulfate Phosphate Sodium Copper (I) Ammonium Calcium Ferrous [Iron (II)] Ferric (Iron (III)] Aluminum
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...
Convert each compound name into its chemical formula, then balance the equation. sodium sulfide + copper (II) chloride à copper (II) sulfide + sodium chloride
Arrange the following ions in order of increasing ionic radius: chloride ion, potassium ion, sulfide ion, calcium ion Enter the FORMULA for each ion in the boxes below.
Write the formula for an ionic compound formed from 02- with each of the ions. magnesium ion: sodium ion: aluminum ion:
Sodium (Na) atoms are larger than chlorine (Cl) atoms, but in NaCl sodium ions (Na+) are much smaller than chloride (Cl-) ions. Discuss why there is a change in size of each element (i.e., why is Na --> Na+ a decrease in size and Cl --> Cl- is an increase in size).
When sodium chloride dissolves in water, the ions dissociate: NaCl (s) à Na+ (aq) + Cl- (aq) Write ionic equations, similar to the one above, that describe how NaNO3 and NaCH3COO each dissociate as they dissolve in water. Include heat as a reactant or product in each equation
When sodium chloride dissolves in water, the ions dissociate: NaCl (s) Na+ (aq) + Cl- (aq) What is the sign of the change in Gibbs free energy (DG) for each process in the forward direction?
Q 6: Four ions (Na+Na+, Cl−Cl−, Na+Na+, and Cl−Cl−) in a row are each separated from their nearest neighbor by 4.5×10−10 mm . The charge of a sodium ion is +e+e and that of a chlorine ion is −e−e. Determine the electric force exerted on the chlorine ion at the right end of the row due to the other three ions. (+x+x to the right) Express your answer with the appropriate units.
