Tectonic plates are pieces of Earth’s crust, and mantle referred to as the lithosphere. They mainly consist of two types of material: oceanic and continental crust. Some of the most famous theories of the movement of tectonic plates involved gods of Greek mythology. For instance, many people believed the popular Greek king of the ocean, Poseidon, was responsible for Tsunamis, vicious waves, and even the expansion of the ocean. He was responsible for the movements of the ocean at the time. But nowadays, we notice, based on scientific and environmental facts, that the tectonic plates might have been shifting due to the intense heat in the Earth’s core, causing the mantle’s lithosphere to move.

A book with a weight of 12 N rests on its back cover. If the back cover measures 0.21 m by 0.28 m, how much pressure does the bo
erik [133]

Answer:

option D = 204 Pa

Explanation:

Given data:

Weight of book = 12 N

Area of book =  0.21 m × 0.28 m = 0.0058 m²

Pressure of book = ?

Solution:

formula

pressure = force / area

P = f/ A

now we will put the values in formula,

P = 12 N/ 0.0058  m²

P= 204 Nm⁻²      ( Nm⁻²= Pa)

P = 204 Pa

Dmitriy789 [7]

Answer:

For the most part, non-metals (excluding Nobel gases) are the most likely to form covalent bonds. Pure covalent bonds are formed between atoms with the same electronegativity, ie. they are trying to hold on to the electrons in the bond with the same strength.

What’s the PH and OH- of 6.0 x 10^-10?
Zarrin [17]

Answer:

The answer to your question is pH = 9.2;  [OH] = 1.58 x 10⁻⁵

Explanation:

Data

[H⁺] = 6.0 x 10⁻¹⁰ M

pH = ?

pH definition. pH measures the hydrogen concentration. pH measures the acidity and the alkalinity of a solution. A solution is acid if the pH goes from 0 to 6.9, a neutral solution has a pH of 7 and an alkali solution has a pH from 7.1 to 14.

pOH measures the [OH⁻] concentration

Formula

             pH = -log[H⁺]

             pH + pOH = 14

-Substitution

            pH = -log[6 x 10⁻¹⁰]

-Simplification

            pH = - (-9.2)

            pH = 9.2

-Calculate pOH

            pOH = 14 - pH

            pOH = 14 - 9.2

            pOH = 4.8      

-Calculate the concentration of OH⁻

           pOH = -log[OH⁻]

           [OH⁻] = -antilog4.8

           [OH] = 1.58 x 10⁻⁵
