FeCl3 + NaOH → Fe(OH)3 + NaCl​
Sunny_sXe [5.5K]

Answer:

FeCl₃  +  <u>3</u>NaOH  →  Fe(OH)₃  +  <u>3</u>NaCl​

Explanation:

You are given a skeleton equation, or unbalanced equation.

FeCl₃  +  NaOH  →  Fe(OH)₃  +  NaCl​

<u>Count the number of atoms on each side</u>. If there is 1 atom, the subscript is not written. If the subscript to the right of a bracket, it belongs to each element in the bracket.

Reactants     →       Products

Fe  1                        Fe  1

Cl   3                       Cl   1         Not balanced

Na  1                        Na  1

O   1                         O   3        Not balanced

H   1                         H   3        Not balanced

<u>The number of each element must be the same in the reactants and products.</u> We can see that Cl (chlorine), O (oxygen) and H (hydrogen) have different numbers.

<u>Write in coefficients in front of formulas</u> (separated by + sign). Coefficients multiply each subscript (or "1" if not written) in the formula. <u>Recount the atoms until you have equal reactant and product atom numbers.</u>

I see that I need more chlorine in my products. Multiply the formula that has "Cl" by 3.

FeCl₃  +  NaOH  →  Fe(OH)₃  +  3NaCl​

Reactants     →       Products

Fe  1                        Fe  1

Cl   3                       Cl   3          Cl is balanced now.

Na  1                        Na  3         Not balanced

O   1                         O   3         Not balanced

H   1                         H   3         Not balanced

Fix the "Na" now. Multiply the formula with "Na" on the left by 3.

FeCl₃  +  3NaOH  →  Fe(OH)₃  +  3NaCl​

Reactants     →       Products

Fe  1                        Fe  1

Cl   3                       Cl   3

Na  3                       Na  3

O   3                        O   3

H   3                        H   3

Each side has the same number of each element. Therefore, this is balanced now.

Balanced formula:

FeCl₃  +  <u>3</u>NaOH  →  Fe(OH)₃  +  <u>3</u>NaCl​

Describe what subatomic particle is involved in light emission.
KiRa [710]

Answer:

Option C= light is emitted as electron falls from the excited state to the ground state releasing a photon.

Explanation:

Electrons are responsible for the production of colored light.

Electron:

The electron is subatomic particle that revolve around outside the nucleus and has negligible mass. It has a negative charge.

Symbol= e-

Mass= 9.10938356×10⁻³¹ Kg

It was discovered by j. j. Thomson in 1897 during the study of cathode ray properties.

How electrons produce the colored light:

Excitation:

When the energy is provided to the atom the electrons by absorbing the energy jump to the higher energy levels. This process is called excitation. The amount of energy absorbed by the electron is exactly equal to the energy difference of orbits.

De-excitation:

When the excited electron fall back to the lower energy levels the energy is released in the form of radiations. this energy is exactly equal to the energy difference between the orbits. The characteristics bright colors are due to the these emitted radiations. These emitted radiations can be seen if they are fall in the visible region of spectrum.
