How many molecules are there in 4dm³ of nitrogen gas​
daser333 [38]

There are 1.078 x 10²³ molecules

<h3>Further explanation</h3>

Given

4 dm³ = 4 L Nitrogen gas

Required

Number of molecules

Solution

Assumptions on STP (1 atm, 273 K), 1 mol gas = 22.4 L, so for 4 L :

mol = 4 : 22.4

mol = 0.179

1 mol = 6.02 x 10²³ particles(molecules, atoms)

For 0.179 :

= 0.179 x 6.02 x 10²³

= 1.078 x 10²³

Learning Objectives

Molecules must collide in order to react.

In order to effectively initiate a reaction, collisions must be sufficiently energetic (kinetic energy) to break chemical bonds; this energy is known as the activation energy.

As the temperature rises, molecules move faster and collide more vigorously, greatly increasing the likelihood of bond breakage upon collision.

Collision theory explains why different reactions occur at different rates, and suggests ways to change the rate of a reaction. Collision theory states that for a chemical reaction to occur, the reacting particles must collide with one another. The rate of the reaction depends on the frequency of collisions. The theory also tells us that reacting particles often collide without reacting. For collisions to be successful, reacting particles must (1) collide with (2) sufficient energy, and (3) with the proper orientation.

The isotopes of an element all have the same __(atomic, mass) __number, but they have different __(atomic,mass)__numbers.
Vlad1618 [11]
<h2>The isotopes of an element all have the same __(atomic, mass) __number, but they have different __(atomic,mass)__numbers.</h2>

Explanation:

The isotopes of an element all have the same __atomic  number  __, but they have different __mass __numbers.

The isotopes have same atomic number that is :

  • Same number of electrons
  • Same number of protons
  • same electronic configuration
  • same valence electrons
  • same valency
  • same symbol

The isotopes have different mass number that is :

They differ in number of neutrons .

For example : Isotopes of hydrogen are : H₁¹ , H₁² , H₁³

                       isotopes of Oxygen is : O¹⁶ , O¹⁷, O¹⁸
