What is the chemical formula of calcium chloride? - Socratic
2014年10月27日 · The balanced equation for the reaction between calcium and chlorine is: "Ca(s)" + "Cl"_2"(g)" rarr "CaCl"_2. During this reaction, the calcium atom gives its two valence electrons to two chlorine atoms. Each chlorine atom initially has seven valence electrons.This causes the calcium atom to become a cation with a 2+ charge, and each chlorine atom to …
What is the formula of calcium chloride? - Socratic
2018年2月13日 · Calcium chloride is an ionic compound. #therefore# it is made of ions. As we know, ions can i have #+# or #-# charge but the key idea is that the overall charge of an ionic compound has to balance out to be neutral. Calcium is in group 2 #therefore# it has a 2+ charge. Chlorine is in group 7 #therefore# it has a -1 charge.
What is the ionic formula for calcium chloride? - Socratic
2014年2月2日 · The ionic formula for Calcium Chloride is CaCl_2 Calcium is an Alkaline Earth Metal in the second column of the periodic table. This means that calcium has 2 valence electrons it readily gives away in order to seek the stability of the octet. This makes calcium a Ca^(+2) cation. Chlorine is a Halogen in the 17th column or p^5 group. Chlorine has 7 valence …

Lets take the ionic formula for Calcium Chloride is #CaCl_2# Calcium is an Alkaline Earth Metal in the second column of the periodic table. This means that calcium has 2 valence electrons it readily gives away in order to seek the stability of the octet. This makes calcium a #Ca^(+2)# cation. Chlorine is a Halogen in the 17th column or p5 group.
What is the atomic mass of calcium chloride? - Socratic
2016年6月30日 · 110.98g/(mol) Let's start with the chemical formula of calcium chloride: CaCl_2 To find the molar mass of a compound you would use the periodic table to find the molar mass of each element separately. In our case, our two elements are calcium and chlorine. Next, you have to find the molar mass of Ca (40.08 g/mol) and Cl (35.45 g/mol). From the chemical formula …
What is the mass of 1.2*10^18 formula units of calcium chloride ...
2018年3月20日 · 2.2 * 10^(-4) "g" The thing to keep in mind about formula units is that you need 6.022 * 10^(23) of them to have exactly 1 mole of an ionic compound -> think Avogadro's constant here. In this case, you know that 6.022 * 10^(23) formula units of calcium chloride are needed in order to have exactly 1 mole of calcium chloride. Moreover, you know that calcium chloride …
