2023年11月1日 · Conversely, the other options, Ca2O, MgOH, and NaCl2, do not represent correct formula units for ionic compounds based on the principle of electrical neutrality of compounds. For instance, NaCl2 suggests there are two Chlorine ions (Cl-) …

2018年3月29日 · Calcium oxide, represented as C a O, is the result of the reaction between calcium and oxygen.To understand why it is not C a O 2 , we need to look at the properties of the elements involved.

2024年1月24日 · b. Ca2O - The charge on the oxygen ion is 2-, so we need two Ca²+ ions to balance the charge. The proper ionic formula is Cao. c. Ca (OH)₂ - This is not an ionic compound, but a formula for a covalent compound. Covalent compounds involve sharing of electrons, while ionic compounds involve the transfer of electrons between ions. d.

What is the formula unit for a compound made from Ca and O? A. CaO 2 because the total negative charge on O is two. B. Ca 2 O because the total negative charge on Ca is one. C. CaO because the total positive charge on O is one. D. CaO …

2023年10月9日 · Final answer: The formula unit for a **compound **made of Ca and O is CaO. This is because Calcium (Ca) has a +2 charge and Oxygen (O) has a -2 charge, and they combine in a 1:1 ratio to form a neutral ionic compound.

2023年8月19日 · The correct formula unit of an ionic compound from the provided options is D. NH₄Cl, which consists of the ammonium cation and the chloride anion that balance charges.
