Protective Action Zone is the range instantly neighboring and downwind from the underlying seclusion zone; this zone is in inevitable risk of being defiled via airborne vapors inside 30 minutes of material discharge. Physically securing and keeping up the crisis scene by building up borders and defensive activity zones and denying section to unapproved people.

Why are intermolecular forces generally much weaker than bonding forces?.
swat32

Explanation:

<em><u>Intermolecular forces:</u></em> These are the attractive or repulsive forces acting between two molecule in interaction.

The attractive forces between molecules are of several types based on the interaction between molecules also known as Vander wall forces.

<em><u>Bonding forces:</u></em> They are also attractive forces acting between two constituents (atom, ion, radicals etc) and stabilizes the constituent particles by loss of energy. The bond between any two species are formed by the overlapping of corresponding orbitals.

Whenever positive overlapping occurs between species, the formation of Bonding molecular orbital (BMO) takes place. and when electron enters into BMO it loses energy. Alternative form of explaining the concept is <em>Individual electron possess more energy than the electrons that paired or Bonded.</em>

Now coming to your question,

All the intermolecular forces are formed by weak attractive forces (vanderwall forces) which includes Ion-dipole forces, Ion-induced-dipole forces, Dipole-dipole forces, Dipole-induced-dipole forces, Hydrogen bonds & London forces.

All these forces are temporary and weak, and formed by the poles generated on molecule due to shift of electron, for e.g. Any molecule having more electron at one pole and less electron at another pole then that molecule start acting as charged body when that charged body comes in contact with opposite pole of another charged body the interaction takes place, since the electrons are dynamic and unsteady it's not possible that the pole will keep acting same as before. hence the intermolecular forces are generally weaker.

On the other side the Bonding electrons, are formed by the various strong overlapping such as between Head to Head overlapping leads to formation of Sigma bond which is the strongest bond takes alot of Energy to break & Lateral overlapping lead to formation of pi bond which is also stronger bond than that of Hydrogen bond.

How many atoms are in 2.5 moles of beryllium atoms?
Irina-Kira [14]
As we know that there are avogadro no. of atoms in 9 g of beryllium.
1 mole of beryllium = 6.02 * 10^23 atoms
so 2.5 mole= 6.02*10^23*2.5 i.e = <span>15.055 × 10^23 atoms </span>

In a can of soda (335 grams of soda ) there are 33g of sugar. What is the mass percent of sugar in soda?
Contact [7]

Answer:

9.85% is the mass percent

Explanation:

Mass percent can be determined as mass of solute in 100 g of solution

The solution is soda

Sugar is the solute

(mass of solute / total mass of solution) . 100 =

(33 g / 335g) . 100 = 9.85%

Consider this reaction: 2Al(s) + 3 CuCl2(aq) → 2AlCl3(aq) + 3 Cu(s) If the concentration of CuCl2 drops from 1.000 M to 0.655 M
Yuliya22 [10]

Answer:

r=-0.0115M/s

Explanation:

Hello,

In this case, the rate is computed as:

r=\frac{C_F-C_0}{T_F-T_0}

As the reaction is analyzed during the first 30 seconds, the average rate will be:

r=\frac{0.655M-1.000M}{30s-0s}=-0.0115M/s

Which negative since the cupric chloride is a reagent.

Best regards.
