Answer:
Yes
Explanation:
By definition, the equilibrium constanct, Kc, for the reaction A ⇒ 2B is
= [A]^1 / [B]^2
Substitute [A] = 4 and [B] = 2 in the equation,
[A]^1 / [B]^2
= 4^1 / 2^2
= 1
= Kc
So yes the reaction is at equilibrium.
Answer:
The mass of
4.6

24
atoms of silver is approximately 820 g.
Explanation:
In order to determine the mass of a given number of atoms of an element, identify the equalities between moles of the element and atoms of the element, and between moles of the element and its molar mass.

Molar mass of Ag =#"107.87 g/mol"#
Multiply the given atoms of silver by

Enrichment of uranium-235 is done. Hence, option A is correct.
<h3>What is the meaning of containment?</h3>
The act, process, or means of keeping something within limits the containment of health costs.
Enrichment is a process of increasing the proportion of fissile isotope found in uranium ore (represented by the symbol 'U') to make it usable as nuclear fuel or the compressed, explosive core of nuclear weapons.
Hence, option A is correct.

Atoms
Explanation:
Chemical bonds results from the rearrangement of atoms in a chemical species.
It deals with the various attractive forces joining chemical species togethe.
- When atoms are re-arranged, they form chemical bonds that leads to production of new compounds.
- This is made possible by the exchange or sharing of electrons.
- The driving force for most interatomic bonding is the tendency to have completely filled outer energy levels like the noble gases.
- When atoms are re-arranged in compounds they lead to the production of chemical bonds.
