Totally three atoms
One barium and two chlorine atoms
There are 2 atoms of chlorine and 1 atom of barium in each molecule of barium chloride (BaCl2). Therefore, in 0.550 mol of BaCl2, there are 0.550 mol x (1 Ba + 2 Cl) = 0.550 x 3 = 1.65 mol total atoms.
When BaCl2 reacts with HCl, a double displacement reaction occurs where the Ba2+ and Cl- ions from BaCl2 switch places with the H+ and Cl- ions from HCl, forming BaCl2 and HCl. The resulting products are BaCl2 and HCl.
BaCl2+K2CrO4--------->BaCrO4+2KCl BaCrO4 is a yellow precipitate.
The symbol for Barium chloride is BaCl2.
Barium chloride is the binary compound name for BaCl2.
There are 2 atoms of chlorine and 1 atom of barium in each molecule of barium chloride (BaCl2). Therefore, in 0.550 mol of BaCl2, there are 0.550 mol x (1 Ba + 2 Cl) = 0.550 x 3 = 1.65 mol total atoms.
The compound formed between barium and chlorine would be barium chloride (BaCl2). In this compound, barium has a +2 charge and chlorine has a -1 charge, so two chlorine atoms are needed to balance the charge of one barium atom.

When BaCl2 reacts with HCl, a double displacement reaction occurs where the Ba2+ and Cl- ions from BaCl2 switch places with the H+ and Cl- ions from HCl, forming BaCl2 and HCl. The resulting products are BaCl2 and HCl.
The balanced equation for BaCl2 + K2SO4 -> BaSO4 + 2KCl is: BaCl2 + K2SO4 -> BaSO4 + 2KCl
BaCl2+K2CrO4--------->BaCrO4+2KCl BaCrO4 is a yellow precipitate.
A mole of barium chloride, BaCl2, contains 6.022 x 10^23 formula units, and each formula unit contains 1 barium atom (Ba) and 2 chloride atoms (Cl). So, there are 6.022 x 10^23 barium atoms and 2 x 6.022 x 10^23 chloride atoms in a mole of barium chloride.
The symbol for Barium chloride is BaCl2.
Barium chloride is the binary compound name for BaCl2.
The balanced equation for BaCl2 + K2SO4 -> BaSO4 + 2KCl is BaCl2 + K2SO4 -> BaSO4 + 2KCl.
Two atoms of chlorine are needed, one to accept each of the barium electrons in an ionic compound, barium chloride (BaCl2).
BaCl2 forms an ionic bond. In this bond, the barium atom, which is a metal, donates electrons to the chlorine atoms, which are nonmetals, resulting in the formation of positively charged barium ions and negatively charged chloride ions that are held together by electrostatic interactions.
