Answer:

Oceanic crust, the outermost layer of Earth’s lithosphere that is found under the oceans. Oceanic crust is constantly formed at mid-ocean ridges, where tectonic plates are tearing apart from each other.

Answer:

oceanic crust is the relatively thin part of the earth's crust which underlies the ocean basins. It is geologically young compared with the continental crust and consists of basaltic rock overlain by sediments

the energy that is present in the gasoline in your automobile's fuel tank is a. potential energy b. nuclear energy c. kinetic en

Softa [21]

A. potential energy.
It can't be any of the above questions. When the automobile burns gas it converts the potential energy into chemical energy which intern gets converted into mechanical energy and then into kinetic energy.

I would have thought it would be Chemical potential energy, which is referring to the energy between the bonds in the molecule.
Hoped this helped.

A compound that is composed of only carbon and hydrogen contains 80.0% c and 20.0% h by mass. What is the empirical formula of t

gladu [14]

Solution : Emperical Formula = $CH_{3}$

Emperical Formula - A formula that gives the simplest whole number ratio of atom in a compound.

In the question percentages are given then assume that the total mass is 100grams so that the mass of each element is equal to the percentage given.

Given : 80.0g Carbon

20.0g Hydrogen

First convert the given masses into moles.

$80.0g\text{ C} \times \frac{1 g/mole \text{ C}}{12.0 g/mole \text{ C}}= 6.66\text{mole of C}$

$20.0g\text{ H} \times \frac{1 g/mole \text{ H}}{1 g/mole \text{ H}}= 20.0\text{mole of H}$

Value of each mole divided by the smallest number of moles and then round off.

Moles ratio of the element are

$\frac{6.66}{6.66}\text{mole of C}= 1$

$\frac{20.0}{6.66}\text{mole of C}= 3$

This is the mole ratio of the elements and is repersented by the subscript in the emperical formula.

Emperical Formula = $CH_{3}$

The polar isopropanol molecules are attracted to

Sergio [31]

When water (H2O) is added to liquid isopropanol to form a solution, then polar isopropanol molecules are attracted to polar water molecules at the surface of the water. It forms a solution of rubbing alcohol.

<h3>Isopropanol and water in the solution</h3>

Isopropyl alcohol is water-soluble and forms hydrogen bonds with molecules of water (H2O).

When H2O is added to liquid isopropanol to form a solution, H2O spread in a uniform way in the solution.

These isopropanol molecules can surround H2O molecules, which are carried into the solution.

Please fill out completely for my understanding. Thank-You!

Archy [21]

The atomic number,atomic mass,valence electrons and the formula for calculating the number of neutrons is also given.The following table has been completed below in the attachment.

Explanation:

Atomic Number:the number of protons /electrons present in the nucleus of an atom is called the atomic number.

Mass Number/Atomic Mass:the number of protons and neutrons present in a nucleus

Example: $C_{6} ^{12}$ ;here;6 implies the atomic number and 12 implies the mass number/atomic mass

No.of neutrons=Mass number-Number of protons

Valence electrons:the number of electrons present in the outer most shell of an atom are called valence electrons

Example:If we consider a carbon atom;as its electronic configuration is2,4 and it belongs to 4th group.Therefore the number of valency electrons in carbon is 4.
