help me please!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The reactants in this reaction are sodium and chlorine. Sodium is a soft, silvery-white metal that is highly reactive. Chlorine is a poisonous greenish-yellow gas that has an odor and combines readily with other elements.

This might be the exact question so you might wanna rephrase it but good luck! :)))

A reactant is a substance that undergoes change during a chemical reaction.

A reaction in a chemical experiment is which takes place when there are mixtures between two or more reactants.

There are about four types of reactions which are:

The two, eight, and eighteen electrons can be filled in the first, second, and third energy levels respectively.

The electrons revolve in different orbits are known as energy levels or stationary states. These energy levels are numbered as n = 1, 2, 3…… These values are also known as the principal quantum numbers.

The first energy level is also known as 'K' shell or level. The second energy level is called 'L' shell, the third energy level is 'M' shell, and so on.

The electrons present in the K shell contain the least energy whereas the levels contain more energy that is far from the nucleus.

The first energy level (n = 1) can have maximum two electrons in it. The second energy level ( n= 2) can have maximum eight electrons and the third energy level can fill maximum eighteen electrons in it.

To ensure that everyone enjoys using your pool, it is important to keep the swimming pool pH levels in balance at all times. If the pH is too high, it could cause skin irritation and corrode metal parts on the pool. If the pH is too low, it could create a situation where the chlorine in the pool isn't as effective.

Explanation:

Answer:

Theoretically not directly describing, .Atoms vs Ions an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion. When an ion is formed, the number of protons does not change.

Neutral atoms can be turned into positively charged ions by removing one or more electrons. A neutral sodium atom, for example, contains 11 protons and 11 electrons. By removing an electron from this atom we get a positively charged Na+ ion that has a net charge of +1.

Atoms that gain extra electrons become negatively charged. A neutral chlorine atom, for example, contains 17 protons and 17 electrons. By adding one more electron we get a negatively charged Cl- ion with a net charge of -1.

The gain or loss of electrons by an atom to form negative or positive ions has an enormous impact on the chemical and physical properties of the atom. Sodium metal, for example, which consists of neutral sodium atoms, bursts into flame when it comes in contact with water. Neutral chlorine atoms instantly combine to form Cl2 molecules, which are so reactive that entire communities are evacuated when trains carrying chlorine gas derail. Positively charged Na+ and negatively charged Cl- ions are so unreactive that we can safely take them into our bodies whenever we salt our food.

I have made it in above figure hope it helps

Answer:

2.No. because in an open system, gas will blow up & so, if it's measured, it won't have the equal amount of the reactant. But, if you arrange this reaction in a closed system, then it will be the same.

Answer:

λ  =  1.5 m

Explanation:

Given data:

Speed of wave = 1500 m/s

Frequency of sound = 1000 Hz

Wavelength of sound = ?

Solution:

Speed of wave = frequency × wavelength

by putting values,

1500 m/s  = 1000 Hz ×  λ

λ  =  1500 m/s  / 1000 s⁻¹     (Hz =  s⁻¹ )

λ  =  1.5 m

Answer: 1.5

Explanation:

Well first you do

1500/ 1000= 1.5 which mean

The wavelength is 1.5

Answer:

1280L

Explanation:

Given parameters:

Initial pressure  = 0.727atm

Temperature  = 26.9°C

Initial volume  = 726mL  = 0.726L

New pressure  = 0.412atm

Unknown:

New volume of the gas sample  = ?

Solution:

To solve this problem, we apply boyles law;

            P1V1  = P2V2

P and V are pressure and temperature

1 and 2 are initial and new state

             0.727 x 0.726  = 0.412 x V2

                   V2  = 1.28mL  = 1280L

2NaCl(l) => 2Na(s) + Cl₂(g)

Explanation:

Electrolysis of melt NaCl to form sodium (Na) metal and chlorine (Cl₂) gas.

This is a class of reaction called 'Decomposition Rxns'. For what it's worth, there are 6 distinct compound types that undergo breakdown by decomposition. The acronym C O A C H E can help remember them.

C - Carbonates => CaCO₃(s) => CaO + CO₂

O - Oxides of Metals => 2Fe₂O₃(s) => 4Fe°(s) + 3O₂(g)

A - Acids (Oxoacids) => H₂CO₃(aq) => CO₂(g) + H₂O(l)

C - Chlorates, Bromates & Iodates => 2KClO₃(s) => 2KCl(s) + 3O₂(g)

H - Hydroxides => Ca(OH)₂(s) => CaO(s) + H₂O(l)

E - Electrolysis => see above electrolysis of NaCl(l)

Answer:

2NaCl(l) => 2Na(s) + Cl₂(g)

Explanation:

Isotope given:

                      ¹⁴₆C

In specie written as this;  

  Superscript  = Mass number

  Subscript  = Atomic number

To find the protons, it is the same as the atomic number;

               Protons  = Atomic number  = 6

Neutrons have no charges;

Neutrons  = Mass number - Atomic number  =

 Neutrons  = 14 - 6  = 8

The number of electrons is the same as the atomic number = 6
