Amanda [17]3 years ago
7 0

Answer:

The mixture has no fixed composition.

To form a mixture energy is neither produced nor evolved.

The mixture has no fixed melting points and boiling points.

the Mixture retains the properties of its components.

Components of mixtures can be separated by simple physical methods.

Which energy transformation is represented in the diagram?
Paha777 [63]

A nuclear to thermal and radiant

Explanation:

Nuclear fission is the disintegration of the force that holds the nucleus of the atom together, creating two different but lighter nuclei.

In nuclear fission, it seeks to break the force of attraction or nuclear force that joins the protons and neutrons that form the nucleus of an atom. Neutrons without electric charge are used against the nucleus of the atom to produce enough excitation energy to deform the nucleus into two halves.

Which actions would the nurse implement when a client develops an anaphylactic reaction? select all that apply. one, some, or al
spin [16.1K]

The nurse would want to call a rapid response, place the patient on oxygen, and prepare for the administration of Epinephrine. This drug is the first-line treatment for anaphylactic shock. It will increase blood pressure, decrease swelling, and dilate the airway.

“Nursing is not an easy job. It takes physical and mental stamina to survive a 14-hour shift.” If you believe, you may find yourself thriving. in the midst of activity.

There is much to learn. The exams are difficult, the schedules are complex, and the challenges pile up. All these factors can make life as a student difficult. Nursing is a highly competitive field from the moment you start the application process until you graduate.

When the element selenium (Se) ionizes to have a complete valence shell of electrons, the
Aliun [14]

Answer:

Positively Charged

Explanation:

The is a group XVI and period 4 element of the periodic table with similar physical and chemical to that of tellurium and sulfur. Selenium exist in different allotropic forms, which have different solubility including selenate, selenite and selenium in elemental form

The Se ion in selenate has a positive charge of +6, while the selenate ion has a charge of -2

The Se ion in selenite has a charge of +4, while the selenite ion has a negative charge of -2.

The charge of Se in elemental selenium is 0.

What type of bond is most likely to form between two nitrogen (N) atoms:
IRISSAK [1]

Answer:

B. Nonpolar covalent bond

Explanation:

Between two Nitrogen atoms, a non-polar covalent bond would be formed.

So, what is the nature of a covalent bond, and what makes a covalent bond non-polar?

A covalent bond is a type of bond that forms between two atoms that shares their valence electrons. The valence electrons are donated by the two atoms and they are shared in order to achieve an octet. This bond type is predominantly between atoms that have an electronegativity difference less than 0.5. Using the electronegativity values, we see that a difference of 0 would be obtained.

Due to equal affinities of the two atoms for the valence electrons, none of them will pull the electrons closer to themselves. There won't be any form of charge separation on the two atoms and a Nitrogen molecule will form. This makes the bond type a non-polar covalent type.
