Is CaCl2 formed by a covalent bond?
NO!!! It is TWO(2) ionic bonds. CaCl2 = Ca^(2+) + Cl^(-) + Cl^(-)
Balanced Chemical reaction of HCl on Ca?
The chemical reactin is:Ca + HCl = CaCl2 + H2
What is the molecular formula for calcium chloride?
These are the ions and their charges: Ca+2 Cl-1The charges have to add up to zero, so one +2 calcium ion cancels out two -1 chlorine ions: Ca+2 Cl-1 Cl-1Simplify: CaCl2
What are the elements in CaCl2?
Calcium and chlorineI think you mean CaCl2 (calcium chloride) and if so the elements are calcium and chlorine.
Calcium Chloride Trihydrate formula?
The formula for calcium chloride is CaCl2.2H2O.
What does the 2 mean in CaCl2(aq)?
The 2 in CaCl2 means that there are two Cl (Chlorine) atoms in each formula unit.
Is CaCl2 formed by a covalent bond?
NO!!! It is TWO(2) ionic bonds. CaCl2 = Ca^(2+) + Cl^(-) + Cl^(-)
Balanced Chemical reaction of HCl on Ca?
The chemical reactin is:Ca + HCl = CaCl2 + H2
What does CaCl2 H2O become into?
CaCl2 + 2H2O --> Ca(OH)2 + 2HCl

Calcium Chloride Trihydrate formula?
The formula for calcium chloride is CaCl2.2H2O.
Which number belongs in the blank in order for this to be a balanced equation Na2CO3 plus CaCl2 NaCl plus CaCO3?
The answer is TWO (2)Na2CO3 + CaCl2 --> 2 NaCl + CaCO3
What salt is formed when a solution of calcium hydroxide is neutralized by hydrochloric acid?
CaCl2: Ca(OH)2 + HCl -------> CaCl2 + H2O
What is the balanced equation for hydrochloric acid and calcium hydroxide?
G
How many moles of CaCl2 contain 1.26x1024 formula units of CaCl2?
1 mole CaCl2 = 6.022 x 1023 formula units CaCl2 1.26 x 1024 formula units CaCl2 x 1mol CaCl2/6.022 x 1023 formula units CaCl2 = 2.09 moles CaCl2
Determine the number of moles of Cl in 1.9 mol CaCl2?
Ca-1(40.08)g=40.8g/mol of Ca Cl-2(35.45)g=70.9g/mol of Cl2 40.08g+70.9g=110.98g/mol CaCl2 110.98g CaCl2/1mol * 1.9mol =210.86 g of CaCl2
