Answer:

1. Dipole-Dipole

2. Hydrogen bonding

3. London dispersion forces

Explanation:

- First, you need to be familiar with each of these terms.

- Secondly, you need to know how to calculate electron negetivity.

Once you know both of these things, all you do is match the defintions.

- Hope this helps! If you would like me to thoroughly explain this to you please let me know, as I would be glad to do it.

Indicate how you might prepare acetic acid from ethene

ruslelena [56]

Acetic acid can be prepared from ethane by oxidizing it. Acetic acid is generally a carboxylic acid. These acids can be made by the oxidation of alcohols using potassium dichromate(VI) solution with sulfuric acid. Ethane is made into acetic acid in two steps. First it is formed into an aldehyde and then to acetic acid.

How acidic buffer resist change in pH on addition of acid and base.

andrew-mc [135]

Answer:

Buffers are solutions that resist changes in pH, upon addition of small amounts of acid or base. The can do this because they contain an acidic component, HA, to neutralize OH- ions, and a basic component, A-, to neutralize H+ ions. Since Ka is a constant, the [H+] will depend directly on the ratio of [HA]/[A-].

Drag and drop the terms into the correct locations to describe how the relationship between photosynthetic organisms and animals

g100num [7]

Answer:

Photosynthetic bacteria must take in <u>Carbon Dioxide</u> to live, and they release <u>Oxygen </u> . Animals must take <u>Oxygen </u> to live, and they release <u>Carbon Dioxide.</u>

Explanation:

Photosynthesis:

It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.

Carbon dioxide + water + energy → glucose + oxygen

water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture by chloroplast.

Chemical equation:

6H₂O + 6CO₂ + energy → C₆H₁₂O₆ + 6O₂

Photosynthetic bacteria perform same function as plants. These bacteria contain light harvesting pigments absorb carbon dioxide and release oxygen.

While animals take oxygen and release carbon dioxide to live. This respiration process is opposite to the photosynthesis.

Glucose + oxygen → carbon dioxide + water + 38ATP
