Because the total energy of the enzyme has been used up and actions already complete

Explanation:

Catalyst are substance known to speed up rate of chemical reaction just like taking a short pathway. When velocity of catalyzed reaction reach maximum, at that moment reaction has reach it full potential (there is an equilibrium in reaction). there won't be any changes on further addition, and mostly indicate that Reaction is Complete

Electronegativity is the atom's tendency to attract electrons in a chemical bond

There are two trends to electronegativity:

Looking at a period table, Sb, Sn, Te, and I are all in the same period, so we'll need to decide which element has the highest electronegativity based on the group.

As I belongs to group 7A, the group that is the farthest right based off of the options given, I has the highest electronegativity

A) The magnitude of the charges on CI and O atoms are : +0.16e and -0.16e  respectively

B)  Atom O will have a partial negative charge on the CIO molecule

C) Attached below

D) The formal charge on Cl is +3

A) Determine magnitude of charges on CI and O

Magnitude of charge = dipole moment / bond length --- ( 1 )

where : dipole moment = 1.24 D * [tex](\frac{3.34*10^{-30} C m}{1 D} )[/tex]

             Bond length = 1.60 A° * [tex]( \frac{10^{-10} m}{A^{0} } )[/tex]  

∴  Magnitude of charge = 2.56 * 10⁻²⁰ C

Note : Charge of an electron = 1.602 * 10⁻¹⁹ C

Therefore the magnitude of charges on CI and O atoms is

2.56 * 10⁻²⁰ C * [tex]\frac{1e}{1.602*10^{-19} }[/tex]  = 0.16 e

Therefore

charge on CI = +0.16e

charge on O = -0.16e

Hence we can conclude that A) The magnitude of the charges on CI and O atoms are : +0.16e and -0.16e  respectively and Atom O will have a partial negative charge on the CIO molecule also The formal charge on Cl is +3

K(s) + 2HCl(aq) ----> 2KCl (aq) +H2(g) is an example of single replacement reactions.

A single-displacement reaction, also known as single replacement reaction or exchange reaction, is a chemical reaction in which one element is replaced by another in a compound.

Single-replacement reactions always involve two pure elements and one aqueous compound/solution. In the above reaction, the A and C would be pure elements.

A single replacement reaction, sometimes called a single displacement reaction, is a reaction in which one element is substituted for another element in a compound.

Answer: a) sp and sp hybrid orbitals:

180 degrees

(b) sp and sp hybrid orbitals:

es

120 degrees

(c) sp and sp2 hybrid orbitals:

109.5 degrees

Explanation:

The angle between the following two hybrid orbitals on the same atom is sp and sp hybrid orbitals: 180°, sp and sp hybrid orbitals: 120° and sp and sp2 hybrid orbitals: 109.5°

Hybrid orbitals are defined as the outcome of a model that generates a new set of orbitals by combining atomic orbitals on a single atom.

It can also be defined as a form of atomic orbital that emerges when two or more atomic orbitals of an isolated atom mix.

It can be defined as the forming new atomic orbitals by combining two or more common atomic orbitals.

The process which forms hybrid orbitals are known as hybridization.

There are mainly five types of hybridization.

Thus, the angle between the following two hybrid orbitals on the same atom is sp and sp hybrid orbitals: 180°, sp and sp hybrid orbitals: 120° and sp and sp2 hybrid orbitals: 109.5°

Explanation:

Answer:

3 atoms

Explanation:

Answer:

Every element in a given group has the same number of valence electrons. For elements in the main groups (1-2, and 13-18), the number of valence electrons increases when moving from left to right along any period (row). The noble gases contain a full valence electron shell, which consists of eight electrons.

Explanation:

Hope this helps.

Answer:

Valence Electrons

Explanation:

Say you are looking at a neutrally charged carbon atom, it has 6 electrons. The first electron shell can hold 2 electrons. The next can hold 8, the next can hold 8 and the next can hold ten and so on... Well in the Carbon atom case, it has 6 electrons, 6-2 is 4, so the carbon atom at 4 valence electrons, which actually helps it in making organic molecules, which in turn also helps make something you might have heard of before, organisms, the best example being, humans
