1. During an oceanic plate convergence, the plate will sink
Lorico [155]

Answer:

1. denser

2. subduction

3. divergence

4. hot spots

5. earthquakes

6. An underwater hot-spot volcano occasionally erupts, and the lava solidifies into an island. However, the plate that lies above the hot spot continues to move due to slab pull and ridge push, so the stationary volcano will be in a different location when it erupts again. This forms a new island, and the process may continue.

Classify the following substances as a Bronsted-Lowry acid, Bronsted-Lowry base, Lewis acid, and/or Lewis base.
Margarita [4]

Answer :

HCl : Bronsted-Lowry acid

BF_3\text{ and }^{+}CCl_3 : Lewis-acid

^-H, CH_2O,^-OCH_3\text{ and }NH_3 : Bronsted-Lowry base

^-H, CH_2O,^-OCH_3,CH_3Cl\text{ and }NH_3 : Lewis-base

Explanation :

According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.

According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.

HCl :

It is a Bronsted-Lowry acid that donates protons.

BF_3\text{ and }^{+}CCl_3 :

It is a Lewis-acid that accepts electron pairs.

^-H, CH_2O,^-OCH_3\text{ and }NH_3 :

It is a Bronsted-Lowry base that accepts protons.

^-H, CH_2O,^-OCH_3,CH_3Cl\text{ and }NH_3 :

It is a Lewis-base that donates electron pairs.
