Oxygen gas expands in a container and when pressure is applied it liquifies and occupies a smaller volume
hope that helps <span />
Answer:
Therefore F ∠ 2.5N
Explanation:
Definition of Work:
It is the amount of energy transferred.
Mathematical expression:
W = F × d
By taking the friction into count it will define as:
Input work = work against friction × output work
No we will put the values:
25 J = w + 10 m
j = kg m²/s²
25 kg m²/s² = w + 10 m
when friction is exist then w > 0
25 kg m²/s² - 10 m > 0
15 N > 0
Therefore F ∠ 2.5N
Answer:
The enthalphy change of the given reaction is -280 KJ.
Explanation:
X 2 + 3 Y 2 ⟶ 2 XY 3 Δ H 1 = − 380 kJ ....Eq-1
X 2 + 2 Z 2 ⟶ 2 XZ 2 Δ H 2 = − 130 kJ ....Eq-2
2 Y 2 + Z 2 ⟶ 2 Y 2 Z Δ H 3 = − 260 kJ ....Eq-3
4 XY 3 + 7 Z 2 ⟶ 6 Y 2 Z + 4 XZ 2 ΔH ....Eq-4
<em>By Hess law,</em>
<em> The heat of any reaction ΔH for a specific reaction is equal to the sum of the heats of reaction for any set of reactions which in sum are equivalent to the overall reaction:</em>
Eq-4 can be manipulated as,
Eq-4 = -2(Eq-1) +2(Eq-2) +3(Eq-3)
By Hess law, same happen with their enthalphy
Therefore,
ΔH = -2(ΔH1) + 2(ΔH2) + 3(ΔH3)
= -2 × -380 + 2 × -130 + 3 × -260
= -280 KJ
Organic molecules can be defined as carbon-containing molecules found in living things.
<h3>What are organic molecules?</h3>
They are chemical compounds that are mainly made up of carbon atoms.
<h3>Characteristics of organic molecules</h3>
- They derive their three-dimensional configurations primarily from their carbon skeletons.
- A major function of these molecules in living systems is to form the structural components of cells and tissues.
Therefore, we can conclude that the organic molecules are those that come from living beings, that is, they are compounds of biological origin, which contain carbon.
