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 atoms of calcium are present in 60.8 g of calcium?
First you need to find how many moles of calcium that is. Since 1 mole of calcium is 40.078g you need to divide 60.8g by how much is one mole (60.8 / 40.078 = 1.517 moles). Once you know how many moles you have (1.517) you can find how many particles there are. There are 6.02 *10^23 atoms in one mole (Avagadro's number), so your final answer will be, 6.02*10^23 x 1.517 = 9.132 * 10^23
Can a polyatomic ion form chemical bonds.?
A polyatomic ion can form an ionic bond with another ion, and an ionic bond is a type of chemical bond. Some examples: One mole of ammonium ions plus one mole of chloride ions produces one mole of ammonium chloride. NH4+ + Cl- ---> NH4Cl One mole of magnesium ions plus two moles of nitrate ions produces one mole of magnesium nitrate. Mg2+ + 2NO3- ---> Mg(NO3)2
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 calcium ions are present in 166.5grams of calcium chloride?
The chemical formula for calcium chloride is CaCl2, and its formula weight is 110.99. The formula shows that each formula weight of calcium chloride contains one mole of calcium ions. In 166.5 grams, there are 166.5/110.99 or 1.500 formula weights of calcium chloride and the same number of moles of calcium ions.
How many ions are there in one mole of NaCl?
Answer: 12,044 282 58.1023 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 ions does MgBr2 have?
One formula unit of MgBr2 has three ions; one Mg2+ ion and two Br- ions. One mole of MgBr2 formula units has one mole of Mg2+ ions and two moles of Br- ions, for a total of three moles of ions.
Why one mole of calcium chloride would be more effective than one mole of sodium chloride?
Effective as coolant in ice: because there are 3 ions in solution (in stead of 2 for NaCl)
How many ions of Na plus are released by 1 mole of NaOH?
Since NaOH is a strong base, one mole (6.022x1023) of Na+ ions are formed when one mole of NaOH dissolves in 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 chloride ions are in a sample of salt that contains one mole of CaCl2?
1.2044 x 1024 chloride ions
How many sodium ions are in a sample of salt that contains one mole of Na3PO3?
1.8066 x 1024 sodium ions
How many moles of oxygen are in one mole of calcium carbonate?
1 mole CaCO3 (3 mole O/1 mole CaCO3) = 3 moles oxygen
