Answer:
The pH of a solution is simply a measure of the concentration of hydrogen ions,
H
+
, which you'll often see referred to as hydronium cations,
H
3
O
+
.
More specifically, the pH of the solution is calculated using the negative log base
10
of the concentration of the hydronium cations.

Now, we use the negative log base
10
because the concentration of hydronium cations is usually significantly smaller than
1
.
As you know, every increase in the value of a log function corresponds to one order of magnitude.

How many moles would there be in 1.5x10^24 molecules of water?
Answer:
5.85 moles
Explanation:
Moles in (3.52 X 10^24) molecules of water. 3.52 x 10^24 molecules x `1mol/6.02 x 10^23 molecules = 5.85 moles of H2O.
The number of protons in one atom of an element determines the atom’s?
The number of protons in one atom of an element determines the atom's identity, and the number of electrons determines its electrical charge. The atomic number tells you the number of protons in one atom of an element. It also tells you the number of electrons in a neutral atom of that element.
The number of protons in one atom of an element determines the atom’s atomic number.
What is atomic number?The atomic number is the number of protons present basically in an atom's nucleus. The number of protons characterize the individuality of an element i.e., an element with 6 protons is a carbon atom, no matter however many neutrons may be prevalent.
The mass number of an element is determined by the number of protons and neutrons combined: mass number = protons + neutrons.
To determine the number of neutrons in an atom, subtract the number of protons, or atomic number, from the mass number.
The atomic number is the number of protons in a nucleus that always equals the number of electrons in orbit around that nucleus (in a nonionized atom).
Thus, it can be concluded that the atomic number is determined by the number of protons in atom.

PLEASE HELP ME . what is frequency of a photon with an energy of 5.75 x 10^-19
Answer:
So:
Explanation:
We have the formula E = hf where R is the energy, h is planck's constant, and f is the frequency. (Planck's constant is about 6.62607004 × 10-34 m2 kg / s). We can put this into the formula to get the frequency equal to about 8.678 x 10^14

A chemical change happens when one chemical substance is transformed into one or more different substances, such as when iron becomes rust. Chemical changes occur through the process of chemical reactions, and the resulting substances have different properties because their atoms and molecules are arranged differently.

How many electrons will a neon (Ne) atom have when it has no charge?
Answer:
hope it helps you
Explanation:
Once one shell is full, the next electron that is added has to move to the next shell. So... for the element of NEON, you already know that the atomic number tells you the number of electrons. That means there are 10 electrons in a neon atom.

What if you broke off a piece of cement (or bread) so that it was only half the volume of the original piece? What would happen to
the mass?
Answer:
The mass is also half of the mass of the original piece
Explanation:
Recall that the volume of a substance is defined as mass/volume. The density of substances is a constant. Hence, if a break off a piece of cement or bread such that what remains is only half the volume of the original piece, the mass of the new piece must also reduce to half of the mass of the original piece so that the volume of the material will remain constant.
Hence the answer above.
What words come to mind when you hear the word Philosophy?
Answer:
The words I think of when I hear philosophies are knowledge and reasoning.
Explanation:
So, if you have seen other responses, you would see "love of wisdom." But, there is more to it. When someone says the philosophy usually, someone would think of knowledge or reasoning. When you reason, you reflect, learn, and form opinions using methods of philosophy. So when doing this, you can reason with someone. You could also have "reasoning" with an object or when having a conversation.
You can have an emphasis and an impact when knowing, supported with reasoning. Even though the definition of wisdom, the quality of having expertise, "knowledge" and good judgment; the quality of being wise, wisdom arises from wise-dom, and which is a synonym to philosophy. When your wise and have "knowledge" you, "know something."
When you think of philosophy, the study of the intellectual foundation of a department of knowledge or expertise, you assume that it's wise, or wise-dom, but no. Love of wisdom originates from, "The feeling of love in being wise." As a result, you could tell that philosophy is the love of being wise. Being wise has a reasoning behind it. There is a reason to be wise. People want to be smart and be intelligent for a reason. You want to be a unique person and want to have a justification in a section of experience.
When thinking of it, it's like you are studying knowledge. You are not practicing wisdom. You can't practice being a wise person. It comes with being a Christian or being in that culture, or whatsoever. But you can study knowledge. Each mindset comes with being or "knowing" something. When thinking about each decision, you have to have reasoning behind it.
So, when you consider philosophy, think of "the" philosophy, the roots of it. You have to have a reason to back it up, with reasoning and details. You become a person who displays knowledge. You do not show wisdom through a philosophy. With being wise, you only know certain things. With the information, you know it all. With reasons you don't just have back up you have everything.
When a police officer is trying to decide if a driver is speeding, what is his point of reference?a. The ground b. His car c. The speed limit d. All of the above
Answer:
C. The speed limit.
Explanation:
If the car was the point of reference then he would be looking at his car not the speed the car is going. If the ground was the reference then he would be looking at the ground and not how fast the car is going. So that means that the officer is determining how fast the car is going compared to the speed limit.

Suppose Highlinium-308 can also undergo positron emission
to produce the new element Burienium. What is Burienium's atomic number?
Answer:
The atomic number of burienium will be 307.
Explanation:
During positron emission proton is converted into the neutron and one electron neutrino with positron is released. It means the atomic number will be reduce by one and atomic mass remain same.
For example:
²³Mg₁₂ → ₁₁Na²³+ e⁺+ Ve
Similarly, when highlinium-308 undergoes positron emission the new element burienium is produced and the atomic number will be 307 while atomic mass remain same.
Properties of beta radiations:
Beta radiations are result from the beta decay in which electron is ejected. The neutron inside of the nucleus converted into the proton an thus emit the electron which is called β particle.
The mass of beta particle is smaller than the alpha particles.
They can travel in air in few meter distance.
These radiations can penetrate into the human skin.
The sheet of aluminium is used to block the beta radiation
What units do scientists use to measure temperature and time?
Answer:
Scientists commonly use two equivalent units of temperature, the degree Celsius and the kelvin.
Explanation:
1. Why is it important to take the temperature of the closed system(the box) and the ice water
before we start the demonstration?
It is important to take the temperature of your materials before you begin a demonstration so you can see the change in particle movement as you do the demonstration or after you finish.
