Answer:
[Y₂] = 31.25M
Explanation:
Based on the chemical reaction:
2X(g) + Y2(g) ⇌ 2XY(s)
We must define the equilibrium constant, K as:
K = 20 = 1 / [X]²[Y₂]
<em>Where</em> [X] and [Y₂]<em> are the equilibrium concentrations of each gas.</em>
<em />
If [X] = 4.0x10⁻²M:
20 = 1 / [4.0x10⁻²M]²[Y₂]
0.032 = 1 / [Y₂]
<h3>[Y₂] = 31.25M</h3>

Answer:
2–Ethyl–3–methlypentanal.
Explanation:
To name the compound given in the question above, we must observe the following:
1. The functional group of the compound is Alkanal i.e Aldehyde,
—CHO and it is located at carbon 1.
Note: the aldehyde functional group is always at carbon 1 and there will be no need to state it's position in the compound.
2. The longest continuous carbon chain is 5 i.e pentane. But the presence of the functional group will replace the –e at the end of pentane with –al, making the name to the pentanal.
3. The substituents attached are:
a. Ethyl, CH2CH3 at carbon 2.
b. Methyl, CH3 at carbon 3.
4. Combine the above to get the name of the compound.
Therefore, the name of the compound is:
2–Ethyl–3–methlypentanal.

Given
5.6 mg of a micro computer
Required
The amount of chip
Solution
A mole is a number of particles(atoms, molecules, ions) in a substance
1 mole = 6.02.10²³ particles
Can be formulated :
N = n x No
N = number of particles
n = mol
No = 6.02.10²³ = Avogadro's number
mass = 5.68 mg = 5.68 x 10⁻³ g
mol :
= mass : MW
= 5.68 x 10⁻³ g : 28 g/mol
= 2.03 x 10⁻⁴
The number of atoms :
= 2.03 x 10⁻⁴ x 6.02.10²³
= 1.22 x 10²⁰
