Answer: D. hops

A beer is a beverage which consists of  90% water, barley, hops and yeast. Yeast is a type of fungus that is used to conduct natural fermentation of maltose sugar in the barley grain. Hops is the ingredient which is used to enhance the quality and flavor to the beer drink. It is added to balance the extreme sweetness of the maltose sugars in the beer drink and provides it a bitter taste.

lana [24]

Answer:

heat and pressure

Explanation:

A metamorphic rock is a changed rock. It is formed a result of mineral changes in a pre-existing rock in the presence of temperature and pressure conditions.

Metamorphic transformation in rocks begins to occur when minerals starts to change from their original and usual form. Most metamorphic rocks are formed as a result of burial into deep seated environment or when subjected to conditions that can elevate the temperature and pressure in a rock.

Answer:

NaCl and water: Ion - Dipolo forces

NaCl and Hexane: Ion-ion force between Na+ and Cl− ions and London dispersion force between two hexane molecules

Explanation:

<u><em>NaCl and water:</em></u>

The <em>ion-dipole force</em> is established between an ion and a polar molecule.  Polar molecules are dipoles, they have a positive end and a negative end.

H2O has an important charge separation in its atoms (the H has a positive partial charge and the O has a negative partial charge) and this causes permanent electrical dipoles in the water molecules.

Sodium chloride is an ionic compound formed of positive and negative charge ions, Na + and Cl-. Depending on their charge, these ions will be attracted to opposite charges in the water molecules (H attracts chloride ions and O attracts sodium ions), causing the salt to dissolve in water.

<u><em> NaCl and Hexane:</em></u>

The dispersion forces of London occur between apolar molecules, and they occur because when two molecules approach a distortion of the electronic clouds of both originates, generating in them, transient induced dipoles, due to the movement of the electrons, so it allows interact with each other.

Hexane is a non-polar molecule, which are those that have no charge separation within the molecules. Then there is <em>London dispersion force between two hexane molecules. </em>

On the other hand, the <em>ion-ion force</em> is produced between ions of the same or different charge, where ions with charges of opposite sign attract each other and ions with charges of the same sign repel each other. This is the force that occurs <em>between the NaCl ion</em>s.

Please help me, Thank you!
Phantasy [73]

Answer:

2

Explanation:

The atom shown in the image has 2 core electrons.

Electrons are the negatively charged particles within an atom. Therefore the total number of electrons surrounding the nucleus in the given specie is 7.

 So;

   We have 2 core electrons

   And 5 valence electrons

The core electrons are the inner orbital electrons.

The valence electrons are the outermost electrons.
