If an atom has the same equal amount of electron and proton is it charged or uncharged ​
Doss [256]

Answer:

Neutral or uncharged

Explanation:

The positive charge on a proton is equal in magnitude to the negative charge on an electron. As a result, a neutral atom must have an equal number of protons and electrons.

What is the Chemical Formula and Net Ionic Equations for all three solutions.
AlladinOne [14]

Answer:

See answer below

Explanation:

As you are asking for chemical formula and ionic equation, then, I will assume that after the station #3 below, are the solutions you are requiring.

You are also not specifing if you want for example, result of solution 1 + solution 3. If you need that, please post that on another question.

Now for the chemical formula, you need to identify the elements in all 3 solutions, and also the type of compound.

<u>1. Solution 2 Potassium Iodide: </u>

In this case we have Potassium on one side, and Iodine on the other side, the symbol for those are K and l. As Potassium have the +1 oxidation state, cause is the only one that it can have, when it's next to an halide like chlorine or bromine, it will form a binary salt. The halides, usually work with the lowest oxydation state. In the case of Iodide it will be -1, so, the formula will be:

KI

And the net ionic equation will be the chemical equation that shows how the charges and atoms are balanced. In this case it would be:  

K⁺ + I⁻ ------> KI

<u>2. Solution 1 and 3, Lead (II) nitrate and Sodium carbonate: </u>

In this case I will work with both, because both of the solution are tertiary compounds. In this cases, we have two tertiary salt, The Sodium symbol is Na, and is working with it oxydation state +1. Carbonate is an anion and have the formula CO₃ working with the oxydation state -2. Lead can work with oxidation state +2 and +4. It's symbol is Pb. Nitrate is NO₃ and works with oxydation state -1 instead.

The chemical formula and ionic equation for both will be:

Lead(II) nitrate: Pb(NO₃)₂

Sodium Carbonate: Na₂CO₃

And the net equations:

Lead nitrate: Pb²⁺ + 2NO₃⁻ ------> Pb(NO₃)₂

Copper sulfate: 2Na⁺ + CO₃²⁻ -------> Na₂CO₃

Hope this helps

silicon, tin, and lead are all in the same group. the density of tin is about 7.28 g/cm3 and the density of lead is about 11.34
Sophie [7]

The atom's radius and mass increase from top to bottom. The density of elements from top to bottom also increases in a periodic table.

Density of Sn= Mass of Sn/Volume of Sn

                     =24.3968/7.28

                     =3.49 g/ml*ml/cm³

                     =3.49 g/cm³

It is accurate to assume that the density of Sn will fall between that of Si and lead .  the mass number and radius of the atoms increase from group to group as we move from top to bottom in a periodic table.. The density rises because the increase in mass number is greater than the increase in radius. Simply multiplying by the molar mass of the gas  allows one to derive the formula for mass density from the formula for number density. Do not forget that the mass is equal to the moles (n) times the molar mass (M).  Smaller masses can be measured in grams instead of kilograms (kg), which is the standard SI unit for mass.

HOW DO THE STATES OF MATTER FIT INTO THE K-M THEORY? PLS NO LINKS
saw5 [17]

Answer:Matter can exist in one of three main states: solid, liquid, or gas. Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around.
