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 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.
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-).
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 chemical formula for calcium phosphide is Ca3P2
