Answer:
If the temperature is increased, the average speed and kinetic energy of the gas molecules increase.
Explanation:
Answer:
0.1 moles of magnesium
Explanation:
Mg(s) + 2CH3COOH(aq) -------> Mg(CH3COO)2(aq) + H2(g)
Since the reaction is 1:2 in mole ratio,
1 mole of magnesium reacts with 2 moles of ethanoic acid
x moles of magnesium will react with 0.2 moles of ethanoic acid
2x = 0.2
x = 0.2/2 = 0.1 moles of magnesium used
N-Octanol and water are chosen because the connection between a substance's hydrophilicity and lipophilicity is measured by 
(n-Octanol/Water partition coefficient). When a chemical is more dissolves in fat-like solvents like n-octanol, the value is more significant than one, when it's more dissolved in water, the value is lower.
What is the partition coefficient?
- The partition coefficient for the two-phase network comprising n-octanol and water is known as the value. N-Octanol-Water Partition Ratio is another name for it.
- The connection between a substance's hydrophilicity (its ability to dissolve in water) and lipophilicity (its ability to dissolve in fat) is measured by . The value is bigger if a drug is more accessible in fat-like liquids like n-octanol and less if a compound seems more water-soluble.
- Owing to linkage or fragmentation, substances that are involved in the octanol-water combination as multiple synthetic entities are each given a unique ratio.
So, N-Octanol is chosen because it has a carbon/oxygen ratio that is comparable to that of lipids and because it shows both hydrophobic and hydrophilic properties. N-octanol, therefore, resembles the makeup and characteristics of cells and other living things.
