Cell wall, central vacuole, and chloroplasts to name a few.
- Explanation is to study cell structure. It is simply a matter of becoming familiar with the organs in the various cells; that is where one starts in biology.
Answer:
a) ΔH°rxn = -9.2kJ/mol
b) ΔH°rxn = -9.2kJ/mol
Explanation:
Using Hess's law, you can find ΔH of a reaction from ΔH of formation of the substances involved in the reaction, thus:
ΔH°rxn = ∑(BE(reactants)) − ∑(BE(products))
Or:
ΔH°rxn = ∑(nΔH°f (products)) − ∑(mΔH°f (reactants))
For the reaction:
H₂(g) + I₂(g) → 2HI(g)
a) Using the first equation:
ΔH°rxn = ΔH (H-H) + ΔH (I-I) - 2ΔHBE (H-I)
ΔH°rxn = 436.4kJ + 151kJ - 2×298.3kJ
<em>ΔH°rxn = -9.2kJ/mol</em>
<em />
b) Using the second equation:
ΔH°rxn = 2Δ°f (HI) − ΔH°f (H₂) - ΔH°f (I₂)
ΔH°rxn = 2×25.9kJ - 0kJ - 61.0kJ
<em>ΔH°rxn = -9.2kJ/mol</em>

Answer:
hydrogen ion dissolve in water is acid and hydroxide ion dissolve in water is basi
the recation in which oxidation and reduction goes side by side is redox redaction
<u>3.04 </u> liters of propane(C₃H₈) are needed to react with 15.2 liters of oxygen to produce water and carbon dioxide
Explanation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
The mole ratio between the propane and oxygen in the equation is 1 : 5 as can be seen in the equation.
If the amount of O₂ reacting is 15.2 L then the amount of propane required is;
1 : 5
X : 15.2
We cross multiply the ration
5x = 15.2 * 1
X = 15.2/5
X = 3.04
= 3.04 L
