Account for the differences in the physical and chemical properties of dinitrogen and white phosphorous based on their Lewis str
Nookie1986 [14]

Answer:

a-The dinitrogeno is a mononuclear diatomic formed by two nitrogen atoms united by a covalent union instead the white phosphorus is a common allotrope of the chemical element phosphorus, nowadays it exists as molecules integrated by four muscles in a tetrahedral structure

b-In addition to its offensive capabilities, white phosphorus is also a highly efficient smoke agent, capable of rapid burning and producing instant smoke screens. For this reason, white phosphorous ammunition is common in infantry smoke grenades and grenade launchers, as well as tank, armored vehicle, cannon, and mortar ammunition.

The incandescent particles of white phosphorus produced in the initial explosion can produce deep, extensive and painful second and third degree burns. Phosphorus burns carry a higher mortality than other types of burns due to the absorption of phosphorus in the body through the areas reached, damaging internal organs such as the heart, liver or kidney.

These weapons are particularly dangerous to personnel because white phosphorus burns unless it is deprived of oxygen or until it is completely consumed, in some cases reaching the burn to the bone. In other cases, burns may be limited to areas where the skin is exposed because phosphorous particles do not completely burn through clothing. According to GlobalSecurity.org, quoted by The Guardian, "White phosphorus causes painful chemical burn damage."

Explanation:

Each chemical component presents different presentations in their orbits, and different amounts of electrons, this makes them act in different ways, some when reacting can be lethal and others not, on the other hand it is important to consider the simplicity of these molecules and the consequences they generate , and this only happens by the forces of their unions.

Why reaction between phosphorus and oxygen produces four atoms of phosphorus and five atoms of oxygen
andreev551 [17]

Answer:

Reaction between an oxygen and  a phosphorus will produce oxides of phosphorus.

Explanation:

Reaction between oxygen and phosphorus produces four atoms of phosphorus with five atoms of oxygen. Sometimes it produces two atoms of phosphorus and five atoms of oxygen and sometimes four atoms of phosphorus and six atoms of oxygen. It does so depending upon the availability of oxygen. The size of phosphorus atom  interferes with the ability to form a double bonds to the other elements, such as nitrogen, oxygen, etc.

2Al + 6HCl --> 2AlCl3 + 3H2 Aluminium reacts with hydrochloric acid. How many grams of aluminum are necessary to produce 11 L
dem82 [27]

Answer:

8.8g of Al are necessaries

Explanation:

Based on the reaction, 2 moles of Al are required to produce 3 moles of hydrogen gas.

To solve this question we must find the moles of H2 in 11L at STP using PV = nRT. With these moles we can find the moles of Al required and its mass as follows:

<em>Moles H2:</em>

PV = nRT; PV/RT = n

<em>Where P is pressure = 1atm at STP; V is volume = 11L; R is gas constant = 0.082atmL/molK and T is absolute temperature = 273.15K at STP</em>

Replacing:

1atm*11L/0.082atmL/molK*273.15K = n

n = 0.491 moles of H2 must be produced

<em />

<em>Moles Al:</em>

0.491 moles of H2 * (2mol Al / 3mol H2) = 0.327moles of Al are required

<em />

<em>Mass Al -Molar mass: 26.98g/mol-:</em>

0.327moles of Al * (26.98g / mol) = 8.8g of Al are necessaries
