Answer:
D) Dispersion; dispersion
Explanation:
Pentane or heptane are non-polar molecules so both of the , dispersion or london force exists as intermolecular force exists among molecules of pentane or heptane . So these bonds needs to be broken and dispersion interaction takes place between molecules of pentane and heptane. Dispersion interaction of AB type is stronger than AA or BB type.
<h2>
Answer:</h2>
CH4 + 2O2 → CO2 + 2H2O
<h2>
Explanation:</h2>
10 grams of methane reacts with 40g of oxygen in the air. This means that mass from the oxygen in the air is also present in the carbon dioxide, so the mass can appear to increase, whereas in reality it is the mass of the oxygen that has caused the increase.
This reaction obeys the law of conservation of mass. Even though it may to appear so until balanced, all reactions follow the law.
<h3>Further explanation</h3>
Given
Reaction
H₂ (g) + I₂ (g) → 2HI(g)
Required
The equilibrium constant
Solution
The equilibrium constant is the value of the product in the equilibrium state of the substance in the right (product) divided by the substance in the left (reactant) with the exponents of each reaction coefficient
The equilibrium constant for reaction
pA + qB ⇒ mC + nD
So for the above reaction :
