CaS
The ionic bond formula between calcium and sulfur is CaS, where calcium loses 2 electrons to form Ca2+ cation and sulfur gains 2 electrons to form S2- anion. This results in the formation of an ionic compound called calcium sulfide.
The ionic formula for Al3+ is Al^3+ and for S2- is S^2-. When these two ions combine, they form the ionic compound Al2S3.
The correct ionic formula for Ca2+ and P3- is Ca3P2. The charges on each ion must balance to create a neutral compound, so two Ca2+ ions (2x2 charges) are needed to balance out the three P3- ions (3x(-3) charges).
Ferrous is the traditional name of the iron (II) ion. (Fe 2+) The formula for ferrous sulfide is FeS since sulfur has a charge of -2.
The balanced molecular equation is CaCl2 + Na2S -> CaS + 2NaCl. To write the ionic equation, we need to break down the reactants and products into their respective ions. This results in the ionic equation: Ca2+ + 2Cl- + 2Na+ + S2- -> CaS + 2Na+ + 2Cl-. Cross out spectator ions that appear on both sides of the equation to obtain the net ionic equation: Ca2+ + S2- -> CaS.
The ionic bond formula between calcium and sulfur is CaS, where calcium loses 2 electrons to form Ca2+ cation and sulfur gains 2 electrons to form S2- anion. This results in the formation of an ionic compound called calcium sulfide.
Calcium sulfide has the chemical formula CaS.
Ca2+(aq)
The ionic formula for Al3+ is Al^3+ and for S2- is S^2-. When these two ions combine, they form the ionic compound Al2S3.
The correct ionic formula for Ca2+ and P3- is Ca3P2. The charges on each ion must balance to create a neutral compound, so two Ca2+ ions (2x2 charges) are needed to balance out the three P3- ions (3x(-3) charges).
The formula for calcium sulfide is CaS. It consists of one calcium ion (Ca2+) and one sulfide ion (S2-).
The ionic compound formed between calcium and sulfur is calcium sulfide, with the chemical formula CaS. In this compound, calcium has a 2+ charge and sulfur has a 2- charge, resulting in a neutral combination.
Ca2+ + 2 I- --> CaI2
Ferrous is the traditional name of the iron (II) ion. (Fe 2+) The formula for ferrous sulfide is FeS since sulfur has a charge of -2.
The balanced molecular equation is CaCl2 + Na2S -> CaS + 2NaCl. To write the ionic equation, we need to break down the reactants and products into their respective ions. This results in the ionic equation: Ca2+ + 2Cl- + 2Na+ + S2- -> CaS + 2Na+ + 2Cl-. Cross out spectator ions that appear on both sides of the equation to obtain the net ionic equation: Ca2+ + S2- -> CaS.
The formula for the ionic compound formed by calcium (Ca2+) and bromine (Br-) would be CaBr2. The calcium ion has a charge of 2+ while the bromine ion has a charge of 1-, so two bromine ions are needed to balance the charge of one calcium ion.
The ionic compound formed by Ca2+ and F- ions is calcium fluoride.
