Answer:
Gases can be compressed easily because there is a large amount of space between the individual molecules, which are very active and move around at high speed.
Explanation:
When gas is compressed, the particles are forced much closer together, allowing a huge amount of particles to fit in a small space.
Hello! The reactions are catalyzed, or sped up by enzymes. Enzymes have strict conditions they can work under, including a small range of temperature. Temperature increase slows the rate of reaction, and extreme temperature increase can denature, or destroy an enzyme. Hope this helps! :)

Ammonia, because it’s a polar molecule, will get attracted to the hydrophilic end while the vegetable oil (non-polar) will interact with the hydrophilic end. Both, therefore have the capacity to dissolve in soap due to the amphipathic properties of soap.
Explanation:
Soap can be categorized as having amphipathic properties. Soap can be composed of fatty-acid chains co-joined with sodium/potassium ions. The fatty acid chains act as hydrophobic ends while the fatty acid acts as the hydrophilic end. This is why soap is a good washing agent The hydrophilic end attached to the ‘dirt’ that needs to be washed away, while the hydrophilic end interacts with the water molecules. Rinsing then washes away the soap including the ‘dirt’.

Answer:
20.9%
Explanation:
- The percentage by mass of solution is given by dividing the mass of solute in grams by the mass of solution in grams then multiplying it by 100%.
% Mass of solution = mass of solute/mass of solution × 100%
= (27.0 g/ 129.0 g) × 100%
= 20.93%
= 20.9%
