Answer: FeCl_3

Explanation:

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.

FeCl_3 is a compound formed by the combination of iron and chlorine where one atom of iron combines with 3 atoms of chlorine.

This is an ionic compound formed by the combination of Fe^{3+} and Cl^- ions. The neutral ionic compound formed is FeCl_3.

3 molecules of ferric chloride are represented by 3FeCl_3.

The compound FeCl3  is made  of  one atom  and three  atoms  of chlorine


    <u><em>explanation</em></u>

  • FeCl3  is made up of two elements.
  • that is iron  with   Fe chemical symbol  and chlorine with Cl  chemical symbol.
  • There are 3  atoms of chlorine  in FeCl3   because the subscript in front of Cl in FeCl3  is 3.

Arrange the following in order of increasing bond strength of the carbon oxygen bond:
Brilliant_brown [7]

Answer:

The correct option is: Carbonate ion < Carbon dioxide < Carbon monoxide

Explanation:

Bond energy is defined as the average energy needed to break a chemical covalent bond and signifies the strength of chemical covalent bond.

The bond strength of a covalent bond depends upon the <u>bond length and the bond order.</u>

Carbon monoxide molecule (CO) has two covalent bond and one dative bond. Bond order 2.6

Carbon dioxide (CO₂) has two carbon-oxygen (C-O) double bonds of equal length. Bond order 2.0

Carbonate ion (CO₃²⁻) has three C-O partial double bonds. Bond order 1.5

Also, the bond length is <u>inversely proportional to the bond order and bond strength.</u>

Therefore, <u>order of C-O bond length:</u> Carbon monoxide<Carbon dioxide<Carbonate ion

<u>Order of C-O bond order</u>: Carbonate ion<Carbon dioxide<Carbon monoxide

<u>Order of C-O bond strength or energy</u><u>: Carbonate ion<Carbon dioxide<Carbon monoxide</u>

Calculate the energy required to heat 406.0mg of cyclohexane from 33.5°C to 38.9°C . Assume the specific heat capacity of cycloh
N76 [4]

Answer:

Q = 4.056 J

Explanation:

  • Q = m<em>C</em>ΔT

∴ m = 406.0 mg = 0.406 g

∴ <em>C </em>= 1.85 J/g.K

∴ T1 = 33.5°C ≅ 306.5 K

∴ T2 = 38.9°C = 311.9 K

⇒ ΔT = 311.9 - 306.5 = 5.4 K

⇒ Q = (0.406 g)(1.85 J/gK)(5.4 K)

⇒ Q = 4.056 J

75As3- what is it’s protons, neutrons, and electrons?
Aneli [31]

Answer:

Atomic Particles

Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).

How is an elements outer electron configuration related to its position in the periodic table?
Umnica [9.8K]
Well, if you look at group 1 of the periodic table, you will notice a thrend. All elements in group 1 have 1 valence / outer electron. Then you look at period 2, 3, 4 and so on, you will see that the group number corresponds the number of valence/ outershell electrons. Hence, the group determines the electron(s) on the outershell.
