Teniendo en cuenta las definición de evaporación, la respuesta correcta es la primer opción: para separar la sal, Jorge debe usar la Evaporación, porque con este método se evapora el agua y queda únicamente la sal.
El método de separación utilizado para el agua y la sal es: la evaporación.
La evaporación consiste en pasar el soluto disuelto en un liquido a estado gaseoso y ocurre al aumentar su temperatura de forma natural o artificial,. Dependiendo de que se desea evaporar se utiliza el material correspondiente. La técnica mas común es por contacto y puede acelerarse si utilizamos un material conductor dentro del liquido.
En otras palabras, se conoce que la evaporación es el proceso por el cual las distintas moléculas en estado líquido, como lo es en agua, pasan a un estado gaseoso de manera espontánea, siendo este el principal efecto de la evaporación.
Como se mencionó el método de separación utilizado para el agua y la sal es la evaporación. Durante este proceso, al aplicar calor, el agua se convierte en vapor y se libera al aire. La sal, como tiene otro punto de ebullición, no se evapora.
Entonces, la respuesta correcta es la primer opción: para separar la sal, Jorge debe usar la Evaporación, porque con este método se evapora el agua y queda únicamente la sal.

PLEASE HELP ME IF YOU DONE THIS BEFORE Part 1: Introduction
Title
Title your lab report with a few words that
summarize the lab investigation
Purpose
The lab report should begin with one or two
sentences that state the purpose of the
investigation what you want to see, practice, loam
about, or test. The purpose statement answers the
question "What am I trying to find out by doing this
experiment?"
The three most common types of labs are:
inquiry labs, in which you measure how
changing one variable affects another variable
discovery labs, in which you observe a scientific
phenomenon, perhaps for the first time.
forensic labs, in which you gather and analyze
data as evidence to build an argument in
response to a question, as in a court case,
All three types of labs give you an opportunity to
learn important scientific skills and concepts.
Question
At its core, science is about inquiry, or the act of
asking questions and seeking answers. Most labs
begin as the result of a question, which is why the
introduction of your lab report should include a
question. For example, suppose you notice that you
seem to play basketball better at the court in one
park than in another. After conducting research, you
realize that one of the surfaces of the court at the
park is different from that of your driveway. As a
result, you might formulate the scientific question
"What effect does the court surface have on the
height that the basketball bounces?" To answer this
question scientifically, you could perform several
experiments and gather data,
Hypothesis (or Prediction)
A hypothesis is an initial answer to a question, a
possible explanation or expectation based on prior
knowledge or research. Before starting most lábs,
you will formulate a hypothesis. It should be listed in
the introduction of your tab report
A good scientific hypothesis states conditions,
expected results, and possible reasons for those
results, For example, you could respond to the
basketball question with a hypothesis like "If the
court surface is smooth concreto, as the park's
court is, then the basketball will bounce higher,
because smooth surfaces have better contact with
the ball." Like this hypothesis, hypotheses are often
structured using the format "il then, because
which is described below.
The "it' portion of the hypothesis describes
something that you will change in the experiment
• The "then" portion of the hypothesis describes
what you think will happen as a result of that
change
• The "because" portion of the hypothesis
describes the ason why you think that change
will occur
In other laboratory activities you will be asked to
make a prediction. You will conduct background
research, then predict the outcome of a known
scientific process
Special Note about inquiry Labs
For inquiry labs, questions are generally
written in the form of "What is the effect of X on
Y?" Hypotheses will generally be in the form of
X [describe how you will change X during the
experiment), then Y will predict how y will
change in response), because give your
reason." In many inquiry labs the variables
lend themselves to a scatterplot (X-Y plot)
For anyone else who needs help just write an essay on what ionic bonds are. Then write what covalent bonds are. Then write the difference between them. It’s better than getting in trouble for using someone else’s work.
The student guide made it very confusing as if you were doing a project but it’s not, it’s just an essay.
Answer:
Was gonna use some links but {insert anger} brainly doesn't allow it.
Explanation:
There are primarily two forms of bonding that an atom can participate in: Covalent and Ionic. Covalent bonding involves the sharing of electrons between two or more atoms. Ionic bonds form when two or more ions come together and are held together by charge differences.
Search up: "Ionic bonds vs Covalent bonds" if you need more to write about
Iwo atoms that are isotopes of one another must have the same number of what! protons O neutrons electrons all particles
Answer:

What does the term temperature control refer to
Answer:
the term temperature control refers to Thermostats .....
A device called a temperature controller is used to maintain a target temperature at a given level. The typical thermostat seen in homes is the most basic type of temperature controller.
What are the biological temperature control factors?
The hypothalamus, a region of the brain, controls our body's core temperature. The hypothalamus measures our body's temperature and compares it to the average temperature, which is around 37 degrees Celsius.
The hypothalamus ensures that the body produces and maintains heat if our body temperature falls too low.
Progesterone tends to encourage heat conservation and higher body temperatures, whereas estradiol tends to increase heat dissipation.
Therefore, a thermostat seen in homes is the most basic type of temperature controller.

which of these is an effect of an algal bloom
Answer:
An increase growth in microorganisms results in oxygen depletion
Explanation:
The growth of algal bloom is caused due to excessive runoff rich in the nutrients like nitrogen and phosphorous. This run off comes from the agricultural field.
These nutrients aids in the growth of the algae(microorganisms) in large number. This growth forms a layer on the water body and use the oxygen present in the water and makes the water oxygen deficient.
