this can be trick balancing equations but this one is easy. the correct equation is CaCO3--> CaO+CO2. CaO plus CO2 does equal CaCO3 because you are adding the single Oxogen atom in CaO to the double Oxygen atom in CO2. basic maths makes it 1+2=3. Easy!!
ca+ci2 caci2
yes
yes
The reaction is:Ag+ + Cl- = AgCl(s)Silver chloride is an insoluble, white, photosensitive precipitate.
Fe and Cl are chemical elements situated in the periodic table.FeCl2 is a chemical compound.
No, just one covalent (single) bond: Cl-Cl
The number of molecules in 1 mole is avogadros number, 6.022 X 1023. So in o.5 mole ter would be 3.011 X 1023 For H2 N2 O2 CI2 F2 I2 We find in the nature as diatomic-molecular form. So we need to multiply by two their molar mass. 1 mol of hydrogen is 1x2= 2 gram; 0.5 mol of H2 is 1 gram.
CI2+KI=2KCI+I2
2Na+ Cl2 ---> 2 NaCl

no.
Cholride? Chlorine
Ionic
its not two it has to be 3,6 or 1
For 2HCl(g) ==> H2(g) + Cl2(g) the Keq = [H2][Cl2]/[HCl]^2
Fluorine is the more reactive.
For the reaction 2HCl(g) ==> H2(g) + Cl2(g), the Keq = [H2(g)][Cl2(g)]/[HCl(g)]^2
An ionic bond.
