What type of reaction is FeS + 2 HCl > FeCl2 + H2S?

1 answer:

8 0

Double replacement means a reaction that includes two molecules that each have two different ions. After the reaction, the ions pairs have switched, which is what is shown in the above equation. A single replacement would be a very simple reactions such as: 2Fe(II)S + Ov2^2- -> 2Fe(II)O + 2S^2- A decomposition reaction would be shown as this: 2NaCl -(dissolve in water)> 2Na^+ + Clv2^- A synthesis reaction could be the exact opposite: 2Na^1+ + Clv2^1- -> 2NaCl

Of the bonds c-c, cc, and c≡c, the c-c bond is ___

Mkey [24]

The line in between indicates that there is a single bond connecting the two carbon atoms. Atoms can be bonded via single bond, double bond and a triple bond. Among the three, the single bond is the weakest, but it allows for more atoms to connect to it because it leaves 3 more pairs available for bonding.

So in summary, among all the bonds that was given, a c-c bond is the weakest and the longest.

What’s the answer to number 6 ty!!

cluponka [151]

Answer:

0.00032 M

Explanation:

From the question,

Applying the for pH

pH = -log[H⁺]............... Equation 1

Where H⁺ = Hydrogen ion concentration of Hydrochloric acid

Given: pH = 3.50

Substitute into equation 1 and solve for H⁺

3.50 = -log[H⁺]

Taking the log inverse of both side,

H⁺ = 10⁻⁽³⁵/¹⁰⁾

H⁺ = 0.00032 M

Hence the H⁺ of Hydrochloric acid is 0.00032 M

Atoms of different chemical elements can be differentiated based on the number of.

Alona [7]

The atoms of different chemical elements can be differentiated based on the number of protons.

Each chemical element is differentiated by his number of protons. This number of protons is also knowing as atomic number and it is represented by the letter (Z).

The atomic number represented the number of protons in the nucleus of an element. For example:

The element that has only 1 proton in his nucleus is Hydrogen atom.
The element that has 2 protons in his nucleus is Helium atom.

The atom is the smallest part of the composition of matter, it is indivisible and is composed of a nucleus that has protons and neutrons, and around the nucleus there are the electrons.
