<h2>The answer is option b "free energy is zero"</h2>
Explanation
- The reaction that has negative free energy are called exergonic reactions that means the reactants have more free energy than the product formed.
- The reaction that has positive free energy are called endergonic reactions that means the final state or the products formed have more free energy than the initial state or the reactants.
- The reaction that has zero free energy occurs when the free energy of both reactants and the products are same hence the rate of formation of products and reactants are equal.
- Therefore, when reactants and products are being formed at an equal rate the free energy is zero.
Two [hydrogen] atoms and one [oxygen] atom
D ----> Evaporates
Volatile substances evoporates easily :)
Generally speaking, organic molecules tend to dissolve in solvents that have similar physical properties. A good rule of thumb is that "like dissolves like". Meaning, polar compounds can dissolve polar compounds and nonpolar compounds can dissolve nonpolar compounds.
To apply this to the current problem, we are told that the brushes are being cleaned with vegetable oil or mineral oil. In this case, the oils are used as solvents. In order for these solvents to be effective, the compounds they are trying to dissolve must be similar in structure and properties to other oils. Therefore, vegetable oil or mineral oil will be most effective in removing oil-based paints, as these will have the similar properties needed to dissolve in the oil solvents.
Answer:
2.33 mL
Explanation:
Given data
- Initial pressure (P₁): 1 atm (Standard pressure)
- Initial volume (V₁): 80.0 mL
- Initial temperature (T₁): 273.15 K (Standard temperature)
- Final pressure (P₂): 92.0 atm
- Final temperature (T₂): 460°C + 273.15 = 733 K
We can find the new volume using the combined gas law.
