the formula of the compound that is formed between chlorine and calcium is CaCl2

explanation

chlorine (non metal) react with Calcium ( a metal) to form an ionic compound CaCl2

Ionic compound is formed when metal loses electrons to form cation ( a positively charged ion) while non metal gains electrons to form anion ( a negatively charged ion)

An ionic compound is formed when calcium metal(Ca) loses two electron to form Ca2+ cation , while 2 chlorine atom gain one electron each to form cl- anions.

when writing down the formula of ionic compound cation symbol is written first followed by anion symbol.

Therefore the formula of ionic compound formed between chlorine and calcium is CaCl2

Answer:

The answer to your question is Element

Explanation:

Element is a substance whose atoms are all the same because of all the atoms

have the same number of protons, neutrons and, electrons.

Compound is a substance formed when 2 or more atoms combined.

Mixture is a substance formed by 2 or more different kinds of atoms or

compounds.

Phase is a state of matter like solid, liquid or gas.

According to the definitions, we conclude that the figure is an Element.

Calculate the molarity when 135 g of KCl is dissolved to make a 2.50 L solution. Round to two significant digits.

inysia [295]

Explanation:

$\textrm{Molarity of a solution}=\frac{\textrm{Number of moles of solvent}}{\textrm{Volume of solution in Liters}}$

We are given a $2.50L$ solution which contains $135g$ of $KCl$ .

To calculate number of moles of $KCl$ present, we need to find it's molar mass from charts. Molar Mass of $KCl$ is known to be $74.55\frac{g}{Mol}$ .

Number of moles of $KCl$ present = $\frac{\textrm{Given weight}}{\textrm{Molar Mass}}\textrm{ = }\frac{135g}{74.55\frac{g}{Mol}}\textrm{ = }1.81087mol$
