Describe the theory of plate tectonics

Chemistry
1 answer:
miskamm [114]3 years ago

Answer:

The theory of plate tectonics states that the Earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet.

The number of atoms in 2 moles of aluminium is if the 1mole is 6.022*10 the power of 23 or 10^23
patriot [66]

Answer:

1.204 × 10²⁴ atoms

Explanation:

According to this question, one mole of aluminum (Al) atom contains 6.02 × 10²³ atoms.

If two moles of aluminum are given, this means that there will be 2 × 6.02 × 10²³ atoms of aluminum

2 × 6.02 × 10²3

= 12.04 × 10²³

= 1.204 × 10²⁴ atoms.

I was wondering what the answer for this question would be ?
mixer [17]

Answer:

C. H2O is the base and H3O+ is the conjugate acid

Explanation:

According to Bronsted-Lowry acid-base theory, an acid is a substance that loses an hydrogen ion or proton (H+) while a base is a substance that gains an hydrogen ion (H+) or proton. Furthermore, this theory states that, the molecule formed when an acid donates its proton is called the CONJUGATE BASE, while the molecule formed when the base accepts proton is called CONJUGATE ACID.

In this question, the following equation is given:

NH4+(aq) + H2O(aq) ⇌NH3(aq) + H3O+ (aq)

Water (H2O) is the base in this equation because according to Bronsted-Lowry acid-base theory, it accepts an hydrogen ion (H+) while hydroxonium ion (H3O+) is the conjugate acid.
