How many ions are there in one mole of NaC1?
108
What happen to reaction if one mole hydrogen ions and one mole of hydroxide ions?
They will form one mole of water.
Will exactly one mole of calcium hydroxide neutralize exactly one mole of phosphoric acid?
No, because one mole of calcium hydroxide constitutes two equivalents of calcium hydroxide for neutralization, but one mole of phosphoric acid constitutes three equivalents of phosphoric acid for neutralization. Therefore, one mole of calcium hydroxide will neutralize only 2/3 of one mole of phosphoric acid.
How many ions in calciom iodide?
Calcium iodide is an ionic compound composed of one calcium ion (Ca2+) and two iodide ions (I-). Therefore, there are a total of 3 ions present in calcium iodide.
What is the number of calcium atoms in calcium chloride?
Calcium ions have a charge of +2 and chlorine ions have a charge of -1. Because a compound is neutral, you need two chlorine atoms per calcium atom, thus giving us the formula of CaCl2. This tells us that there is one calcium atom in the compound.
What one mole of calcium chloride CaCl contains what?
One mole of calcium chloride (CaCl2) contains one mole of calcium ions (Ca2+) and two moles of chloride ions (Cl-).
Why one mole of calcium chloride would be more effective than one mole of sodium chloride?
One mole of calcium chloride would be more effective than one mole of sodium chloride because calcium chloride provides twice as many ions per formula unit, resulting in a higher concentration of ions in solution. This makes calcium chloride more effective in applications that require dissociation into ions, such as lowering the freezing point of water or enhancing road de-icing.
How many chloride ions are in calcium chloride?
The formula unit for calcium chloride is CaCl2. There are two chloride ions in one formula unit of calcium chloride. We can also say that there are two moles chloride ions in one mole of CaCl2.
How many moles of Na plus ions are there in a moles of NaCl?
There is one mole of Na⁺ ions for every mole of NaCl. This is because each mole of NaCl dissociates into one mole of Na⁺ ions and one mole of Cl⁻ ions in solution.
How many moles of Ca2 ions are in 0.25 moles of calcium titanate?
In calcium titanate, the formula is typically CaTiO3. In one mole of CaTiO3, there is one mole of Ca2+ ions because the subscript in the formula indicates that there is one Ca2+ ion. Therefore, in 0.25 moles of CaTiO3, there are also 0.25 moles of Ca2+ ions.
How many ions of Na plus are released by 1 mole of NaOH?
One mole of NaOH will release one mole of Na+ ions when dissolved in water, as NaOH dissociates into Na+ and OH- ions in solution. Thus, 1 mole of NaOH will release 1 mole of Na+ ions.
How many ions are there in one mole of NaC1?
108
What happen to reaction if one mole hydrogen ions and one mole of hydroxide ions?
They will form one mole of water.
How many moles of oxygen are in one mole of calcium carbonate?
There are three moles of oxygen atoms in one mole of calcium carbonate (CaCO3). This is because there are three oxygen atoms in each molecule of calcium carbonate.
How many sodium ions are in a sample of salt that contains one mole of Na3PO3?
There are 3 moles of sodium ions in one mole of Na3PO3, because there are 3 sodium ions in one unit of Na3PO3. Therefore, there are 3 x 6.022 x 10^23 sodium ions in one mole of Na3PO3.
Will exactly one mole of calcium hydroxide neutralize exactly one mole of phosphoric acid?
No, because one mole of calcium hydroxide constitutes two equivalents of calcium hydroxide for neutralization, but one mole of phosphoric acid constitutes three equivalents of phosphoric acid for neutralization. Therefore, one mole of calcium hydroxide will neutralize only 2/3 of one mole of phosphoric acid.
