In an electron dot diagram, two pairs of shared electrons represents a?

For the reaction A+B↽−−⇀C+D, assume that the standard change in free energy has a positive value. Changing the conditions of the

77julia77 [94]

Explanation:

a. Adding a catalyst

no effect .( Catalyst can only change the activation energy but not the free energy).

b. increasing [C] and [D]

Increase the free energy .

c. Coupling with ATP hydrolysis

decrease the free energy value .

d.Increasing [A] and [B]

decrease the free energy.

Eduardwww [97]

Answer:

E) 4,6,7,1,2,3,5

Explanation:

The correct sequence of events is as follows.
A grated depolarization brings an area of excitable membrane to a threshold.
Sodium channels are activated and open, allowing positively-charged sodium ions to pass through.
The sodium ions then enter the cell, and depolarization of the negatively-charged cell membrane is initiated.
Sodium channels are first inactivated.
The voltage-gated potassium channels then open, allowing for potassium ions to move out of the cell, initiating repolarization.
Sodium channels then regain their normal properties allowing the sodium ions to pass through and making the cell membrane repolarized again.
The cell membrane will reach its resting membrane potential again.
Afterward, a temporary hyperpolarization occurs.

In a molecule of calcium sulfide, calcium has two valence electron bonds, and a sulfur atom has six valence electrons. How many

mote1985 [20]

There are none

<h3>Further explanation</h3>

Given

a molecule of calcium sulfide

two valence electron of Calcium(Ca)

six valence electrons of Sulfur(S)

Required

number of lone pairs of electrons

Solution

Lewis structure shows the form of bonds that occur in the valence electrons of an element or compound

Valence electrons are electrons used in a chemical bond

To achieve stability, the element S needs 2 more electrons which are obtained from 2 electrons from the Ca element,

A lone pair electron means refers to an unshared pair of electrons(not bonding to the other atoms)

This condition usually occurs in covalent bonds

As we know, the bond between Ca, which is a group 2 (metal) with Sulfur in group 16, is an ionic bond because it occurs between metal and non-metal ions, so there is no sharing of electrons, but there is a release of electrons from Ca ions to S ions to form an octet. , so all the valence electrons in S are paired
