Ions formed from Na plus and Cl- are?
Na+ + Cl- --> NaCl NaCl = salt.
How many mol of Ca2 plus ions are in 2.8 mol of Ca3N2?
2.8 moles Ca3N2 (3 mole Ca 2+/1 mole Ca3N2) = 8.4 moles Ca 2+ =============
What ionizes in water to release ions other than H plus and OH?
Common soluble salt (like NaCl) dissociates into ions (Na+ and Cl-) when it is dissolved in water.Ionize in water to release ions other than H plus and OH minus is salts. Acids is ionized in water to release hydrogen ions and a negative ion other than hydroxide.
What kind of solution is sugar water hypotonic or hypertonic?
Hypertonic for human blood fluid means that more than 0.9% NaCl is present (as only solute).This is 9 grams per liter divided by 58.5 grams per mole NaCl or 0.154 moles Na+ AND 0.154 moles Cl- per liter = total of 0.308 moles dissolved particles as hypertonicity.The same hypertonicity is reached with 0.308 / 3 = 0.103 moles CaCl2 per liter (3 particle ions per molecule)
2A3 plus 3B2 6AB If 10 moles of A3 are reacted with excess B2 how many moles of AB will be produced?
The answer is 30 moles.
How many moles of Cl- ions are needed to completely combine with 0.25 moles of Mg plus 2ions?
0,5 moles Cl-
Ions formed from Na plus and Cl- are?
Na+ + Cl- --> NaCl NaCl = salt.
When the solid acid dissolves to form ions how many moles of H plus ions are produced for every mole of acid used?
10000
Does sodium ions plus chloride ions equal sodium chloride?
Yes, sodium chloride is NaCl.
How many oppositely charged ions are clustered around each Na plus and Cl- ion in a NaCl crystal?
6
How many mol of Ca2 plus ions are in 2.8 mol of Ca3N2?
2.8 moles Ca3N2 (3 mole Ca 2+/1 mole Ca3N2) = 8.4 moles Ca 2+ =============
How much NaCl precipitate would be produced if 2 molarity HCl and 1 molarity sodium carbonate react in the reaction Na2CO3 plus 2HCL yields 2NaCl plus H2O plus CO2?
2 moles or 117 gram of NaCl is precepitated
MgO has the same crystal structure as NaCl face-centered cubic How many oxide ions surround each Mg2 plus ion as nearest neighbors?
6

Common soluble salt (like NaCl) dissociates into ions (Na+ and Cl-) when it is dissolved in water.Ionize in water to release ions other than H plus and OH minus is salts. Acids is ionized in water to release hydrogen ions and a negative ion other than hydroxide.
What does copper II chloride plus sodium phosphate yield?
3CuCl2 (aq)+ 2Na3PO4 (aq)> 6Na+ (aq)+ 6Cl- (aq)+ Cu3(PO4)2 (s) Or, 3 moles of copper (II) chloride and 2 moles of sodium phosphate form 6 moles of sodium ions, 6 moles of chloride ions, and a mole of copper (II) phosphate, which is insoluble, and precipitates out of the solution.

30 moles
