Answer:

<h2>The answer is option e</h2>

Explanation:

To find the number of moles we must first find the molar mass of LiCL

From the question

mass = 0.550g

M(Li) = 6 Cl = 35.5

Molar mass of LiCL = 6 + 35.5 = 41.5 g/mol

Then we use the formula

n =  \frac{m}{M}

where

n is the number of miles

m is the mass

M is the molar mass

So we have

n =  \frac{0.550}{41.5}

We have the final answer as

<h3>0.0130 mol</h3>

Chlorine and bromine are elements in Group VII.
Goryan [66]

Explanation:

Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour. Its properties are intermediate between those of chlorine and iodine. Isolated independently by two chemists, Carl Jacob Löwig (in 1825) and Antoine Jérôme Balard (in 1826), its name was derived from the Ancient Greek βρῶμος ("stench"), referring to its sharp and disagreeable smell.

I THINK that that is true. It's just weathering the rock down not change composition. Lemme know if you get it right please! (:

What decides if an atom will be a cation or an anion?
JulijaS [17]

The loss or gain of electrons

Explanation:

The loss or gain of electrons determines if an atom will become a cation or anion.

A cation is a positively charge ion

An anion is a negatively charged ion.

In an atom, we have sub-atomic particles:

 Protons are the positively charged particles

 Electrons are negatively charged

  Neutrons carry no charges

Only electrons can be lost or gained in chemical processes that forms cations and anions.

When a neutral atom gains electron, it has more electrons than protons. This makes it negatively charged and we call it an anion.

When a neutral atom loses an electron, the number of protons is more. We call it a cation.
