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.
Answers
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

2. Ultraviolet radiation has a frequency of 6.8 x 10'5Hz. Calculate the energy, in
joules, of the photon.
Answers
Answer:
[tex]E=4.5\times 10^{-18}\ J[/tex]
Explanation:
It is given that, the frequency of Ultraviolet radiation is [tex]6.8\times 10^{15}\ Hz[/tex]
We need to find the energy of the photon. The formula for the energy of a photon is given by :
[tex]E=hf\\\\\text{Where h is Planck's constant}\\\\E=6.63\times 10^{-34}\times 6.8\times 10^{15}\\\\E=4.5\times 10^{-18}\ J[/tex]
So, the energy of the photon is [tex]4.5\times 10^{-18}\ J[/tex].

How are electrically neutral atoms different than they form
Answers
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.

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

Answers
The IUPAC name for NO is nitric oxide. The correct option is A.
What is IUPAC naming?The International Union of Pure and Applied Chemistry (IUPAC) is a global organization that represents chemistry as well as related sciences and technologies.
The chemical compound's identity is represented by its common and IUPAC names, which differ from one another. Every chemical compound has multiple names.
Complete the following step-by-step response: The IUPAC nomenclature is a standardized name given to organic compounds in accordance with official naming rules.
Nitric oxide, also known as NO, is a colorless gas. It is one of the most important nitrogen oxides.
Nitric oxide is a free radical, which means it has an unpaired electron, which is sometimes represented in its chemical formula by a dot.
Thus, the correct option is A.

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?
Answers
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.

What is the conversion factor used when converting mass to moles?
Answers
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
