A sample of nitrogen (N2) gas in a 10.0L container has a

Chemistry
1 answer:
attashe74 [19]3 years ago
8 0

Answer: The pressure of nitrogen will be 2.0 atm

Explanation:

According to ideal gas equation:

PV=nRT

P = pressure of gas = 1.0 atm

V = Volume of gas = 10.0 L

n = number of moles = ?

R = gas constant =0.0821Latm/Kmol

T =temperature =297K

n=\frac{PV}{RT}

n=\frac{1.0atm\times 10.0L}{0.0820 L atm/K mol\times 297K}=0.41moles

Now again using ideal gas equation :

P=\frac{nRT}{V}=\frac{0.41mol\times 0.0821Latm/Kmol\times 297K}{5.0L}=2.0atm

Thus pressure of nitrogen will be 2.0 atm

What atomic or hybrid orbitals make up the sigma bond between Cl and F in chlorine trifluoride, ClF3
Umnica [9.8K]

Answer:

sp³d¹ hybridization

Explanation:

Given Cl as central element with three F substrates ...

The VSEPR structure indicates 5 hybrid orbitals that contain 2 diamagnetic orbitals (non-bonded e⁻-pairs) and 3 paramagnetic orbitals (single, non-paired electron for covalent bonding with fluorine) giving a trigonal bypyrimidal parent with a T-shaped geometry.

Valence bond theory predicts the following during bonding:

Cl:[Ne]3s²3p²p²p¹3d⁰

=> [Ne]3s²p²p¹p¹d¹

=> [Ne]3(sp³d)²(sp³d)²(sp³d)¹(sp³d)¹(sp³d)¹

giving 3 ( [Cl](sp³d) - [F]2p¹ ) sigma bonds and 2 non-bonded pairs on Cl.

Note the following images:

Non-bonded electron pairs are in plane of parent geometry and Fluorides covalently bonded to central element Chloride forming the T-shaped geometry.

Sr            ⇒ Y         +   e

38                  39             -1

<h3>What is Beta emission?</h3>

This is also known as beta decay in which a beta ray is emitted from an atomic nucleus.

The element formed during the beta emission of strontium is referred to as Yttrium.

For the reaction between solid tetraphosphorus trisulfide and oxygen gas to form solid tetraphosphorus decoxide and sulfur dioxi

<h3>What is a tetraphosphorus decoxide?</h3>

Tetraphosphorus decoxide, () is a non-metal oxide that gives acidic property when dissolved in water.

The name phosphorus decoxide can be interpreted as 4 phosphorus (P) atoms (‘Tetra’), bonds with 10 oxygen (O) atoms (‘Dec’) in a molecule. besides that, it is also known as phosphorus pentoxide.

It can be prepared by heating pure phosphorus with oxygen in blast furnace.

+  →

It is used as a dehydrating agent due to its week van der Waals dispersion forces. Thus, owing to give exothermic reaction when dissolved in watermore precisely, it is a white crystalline anhydrous (without water molecule) solid.

In granular form it can be also used as desiccant as well.

What are two properties of most nonmetals?(1) high ionization energy and poor electrical conductivity(2) high ionization energy
elixir [45]
The two properties of most non metals are high ionization energy and poor electrical conductivity. The correct option among all the options that are given in the question is option "1". In general it is known that nonmetals are very poor conductors of heat and electricity. The nonmetals that are solid are normally very brittle and has very little or no metallic luster at all. Nonmetals are highly reactive and show variety of chemical properties. It can also be pointed out that the nonmetals gain electrons very easily.

What is the chemical formula of the salt produced by the neutralization of potassium hydroxide with sulfuric acid?KSO3KSO4K(SO4)
kakasveta [241]

Answer: The salt produced will be K_{2}SO_{4}

Explanation:

During a neutralization reaction, an acid reacts with a base for producing the correspondent salt, and water.

The strong acids release all the protons avalaible when are dissolved, such as sulfuric acid. As you can see, sulfuric acid have 2 protons ready for being released (H_{2}SO_{4}); and those places have to be occcupied for other ions equivalents to the H+: K+ from KOH in this case.

Therefore the answer will be K_{2}SO_{4}.
