What is the Independent and Dependent Variables for this experiment?
"How does the amount of salt in water affect how an egg floats?"
please help!!
Answer:
The egg is the dependent variable and the salt is the independent variable.
Explanation:
The dependent variable is something that stays the same throughout the experiment. The independent variable is something that might not stay the same throughout the experiment. The egg does not change because we're using an egg and not an egg and then a tomato or a potato, but the salt does change because we're changing the amount of salt in the bowl/plate or anything else that we are using to perform this.
This is kinda long but it explains mostly everything. DM me for more dependent and independent variable help.

You have an empty milk container, and you close the cap on the container. Do the particles of air that you trapped inside the container have mass? Explain how you know.
Answer:
Yes the air particles have mass
Explanation:
Air is mater: it has weight and occupies space. For it to have weight, it has to have a mass. The mass would however be determined by how much volume of air is trapped in the container, but nevertheless, the mass of the air can be obtained.
We also notice that if the container is "popped", the mass of air escapes through one way by the weight exerted on it.
I hope this was helpful.
Answer:
Yes the air particles have mass
Explanation:
You can tell that if the container is pooped open the mass of air escapes
Why do most metals exist in nature as minerals rather than as pure metallic elements?
What is the conversion factor used when converting mass to moles?
In such a conversion, we use the molar mass of a substance as a factor to convert that to mole units into mass units (or, conversely, mass units into mole units).
Then We also established that 1 mol of Al incorporates a mass of 26.98 g (Example). Stated mathematically that is, 1 mol Al = 26.98 g Al
Molar massNow, This relation provides a factor to travel from grams to moles.
which is help to Using the factor 98.08 g / 1 mol: grams H 2 SO 4 = 3.60 Then mol x 98.08 g / 1 mol = 353 g H 2 SO 4

Explanation:
A student combines two clear liquid chemicals together in a beaker. When the two chemicals are combined, bubbles are formed, the solution turns blue, and you can see flakes of something forming on the bottom of the beaker. Is this a physical or chemical change? Why?
Answer:
chemical change
Explanation:
A physical change is one that makes changes to the physical properties of matter. In many cases, the difference is usually reversible. Examples include boiling, melting, freezing, the magnetization of metals, etc.
A chemical change is one in which a new kind of matter is formed. It is usually accompanied by energy changes, i.e., the evolution or absorption of energy in the form of heat or light. This process is not easily reversible. Examples include; combustion, rusting of iron, precipitation, the souring of milk, etc.
From the question given, the combination of two clear liquid in a beaker which results to formation of bubbles and changes in coloration of the solution is a chemical change.

Why does an ion have a charge
Help please:)
Answer:
An ion is charged because the number of electrons does not equal the amount of particles.
Explanation:
Can be positive (meaning more protons than electrons) and it can be negatively charged (meaning there are more electrons than protons).
Hope this helps!
Answer:
An ion has a charge because the number of electrons dont equal the amount of protons in the molecule or atom.
Explanation:
The negative or positive charge depend on wether the atom or molecule has more electrons(-) or protons(+).
How are electrically neutral atoms different than they form
An atom is said to be electrically neutral if it has an equal amount of protons and electrons. On the other hand, an atom is electrically charged if its protons and electrons are not distributed evenly.
What are neutral atoms?Neutral atoms are defined as when an atom has an equal amount of protons and electrons, it also has an equal number of electric charges, both positive and negative. As a result, every element in the periodic table has a neutral atomic structure.
Normal atoms have an equal amount of positive and negative particles and a neutral charge. Accordingly, an atom with a neutral charge is one in which the atomic number is matched by the number of electrons.
Thus, an atom is said to be electrically neutral if it has an equal amount of protons and electrons. On the other hand, an atom is electrically charged if its protons and electrons are not distributed evenly.

What purpose do neutrons serve in the nucleus ? What happens if there are too many or too few neutrons?
Answer:
These nuclei with different numbers of neurons are called isotopes
Answer:
neutrons' main function is to attract each other and keep the nucleus of an atom intact. a nucleus will become unstable if there are too many or too few neutrons in it.
Explanation:
too many= it will undergo beta decay (the neutrons will changes into proton)
too few= there will be an imbalance between forces which leads to nuclear imbalance

Read this passage from "The Secret Life of Walter Mitty."
"Puppy biscuit," said Walter Mitty. He stopped walking and the buildings of Waterbury rose up out of the misty courtroom and surrounded him again.
A woman who was passing laughed. "He said ‘Puppy biscuit,’" she said to her companion. "That man said ‘Puppy biscuit’ to himself."
What does the dialogue in the excerpt show about Mitty?
He is awkward and absentminded.
He is responsible and conscientious.
He is funny and entertaining.
He is sour and nasty.
Answer:
He is awkward and absentminded.
Explanation:
"The Secret Life of Walter Mitty" by James Thurber presets the story of Walter with a dream. The beginning of the story reflects on the idea that the story is more inclined towards the dreams and fantasy-full world rater than reality. Walter's dreams are a mixture of reality and his imagination. He spoke certain words those do not have meaning in reality. He calls himself 'Puppy Biscuit" to which the women reacted with a laugh. This represented his absent-minded character and his appeal towards is dreams.
explain the relationships that are present between the frequency, wavelength, and amplitude of a wave in 3 to 5 sentences.
Answer:
Wavelength refers to the length of a wave from one peak to the next. The amplitude or height of a wave is measured from the peak to the trough. The wavelength is measured from peak to peak. Wavelength is directly related to the frequency of a given wave form.
