1. In the first image, you can see two cacti and a javelina in the background.

2. In picture one, neither of the plants are being disturbed. In picture two, however, the smaller plant is indeed being disturbed by the javelina.

3. The javelina is not eating the cactus on the right because it is stronger in color (?).

4. The cactus the javelina was eating has disappeared.

5. In picture 3, the idle cactus blossomed.

An experiment is performed using 7 liquids; Methanol, Ethanol, Propanol, Butanol, Water, Pentane and Acetone.
charle [14.2K]
A). The weaker the IMF the lower the evaporation rates of each liquid. So Pentane had the weakest IMF and Butanol has the strongest.

b).They all evaporate at different rates because of their differences in their bonds. Not all liquids are the same and they will all most likely evaporate at different times

What is the effect of a catalyst on a reaction? It increases the entropy. It decreases the entropy. It changes the equilibrium.
Leto [7]

Answer: It increases the entropy

Explanation:

Entropy is the measure of degree of randomness or disorder.

Activation energy is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.

A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more molecules can cross the energy barrier and more molecules convert to products. Thus leading to more randomness and more entropy.

Compare the properties of carboxylic acids with the properties of compounds with other functional groups brainly
AnnZ [28]
Carboxylic acids: considered as weak acids due to they ionize in solution to give -COO⁻ and H⁺, they are abundant in nature, they can form intermolecular hydrogen bonds so they exist as dimers (remember that alcohols also can form hydrogen bonds).
- Acids have higher boiling and melting points than corresponding molar mass compounds due to the formation of hydrogen bond
- Aromatic carboxylic acids are solids in nature at room temperature
