Answer:

An atom has a nucleus, made up protons and neutrons, which is surrounded by a cloud of electrons.

Explanation:

An atom is the smallest indivisible part of any element that takes place in a chemical reactions.

These are the fundamental building blocks of every element and even compounds.

  • There are three known subatomic particles found within an atom.
  • Electrons are the negatively charged particles in an atom
  • Protons are the positively charged particles of an atom
  • Neutrons do not carry any charges.

Both protons and neutrons are located within the tiny space called nucleus at the center of an atom.

Electrons moves round in orbitals at the spaces outside of the nucleus.

dinitrogen pentoxide decomposes to form nitrogen dioxide oxygen, following the equation 2N2O5 -> 4NO2. at a certain time poin
Temka [501]

Rate of production of NO₂ = 0.2 M/s

Rate of production of O₂ = 0.05 M/s

<h3>Further explanation</h3>

Given

The rate of N₂O₅ : 0.1 M/s

Reaction

2N₂O₅⇒4NO₂+O₂

Required

The rate of production of NO₂ and O₂ at the same time point

Solution

Rate of disappearance of N₂O₅ = reaction rate x coefficient of N₂O₅

0.1 M/s=reaction rate x 2

<em>reaction rate = 0.05 M/s</em>

The rate of production of NO₂=

Rate of production of NO₂ = reaction rate x coefficient of NO₂

Rate of production of NO₂ = 0.05 M/s x 4

Rate of production of NO₂ = 0.2 M/s

The rate of production of O₂=

Rate of production of O₂ = reaction rate x coefficient of O₂

Rate of production of O₂ = 0.05 M/s x 1

Rate of production of O₂ = 0.05 M/s
