1.The two green substances are not same thing because some of their properties are different and some of them are the same. If they were the same substance, all of their properties would have to be the same.
How could the explanation be improved?
Answer:
Even though the two substances possess many similarities, they have some unique properties. In turn, since they have the same properties, if they were the same substance, it would make matters worse, if the same chemical was in two different places, there would not be a difference between them since they are the same, just as it is with are two different chemicals would have differing properties since they are two properties would vary from one another since they are 2 totally different things!

Here the nuclear decay of phosphorous to give S-32 is an example of beta-decay. Hence, the emitted particle is an electron. Thus, option b is correct.
What is beta decay ?The heavy unstable radioactive isotopes undergo nuclear decay by the emission of alpha or beta particle. Thus, there are mostly two types of decays, alpha decay and beta decay.
In alpha decay, the isotope emits a helium nuclei. Hence, mass number decreases by 4 units and atomic number decreases by 2 units. In beta decay, mass number does not change but atomic number increases by 1.
Here, P-32 undergo beta -decay by emitting an electron to form S -32. Hence, atomic number is increased by one. Therefore, the mission product is an electron option b.

Answer: It is conserved.
Explanation: When the box is pushed across the floor, then floor and box becomes warm which resembles the condition of conservation of energy.
The given problem can be resolved by the concept of energy conservation. The statement of energy conservation says that, "Energy is neither be created nor be destroyed, but it is converted from one form to another.
In the given problem, the person pushes the box across the floor, such that the mechanical energy from the moving arms of person is transferred to the box, and the box and floor becomes warm.
During this process, the energy from the person moving arm is transferred to the box in the form of kinetic energy. And thus kinetic energy is then being transferred to thermal energy or heat energy, due to which the box and floor becomes warm.
Thus, we can conclude that the given case reflects the process of transformation of energy from one state to another, which highlights that during the process, energy is conserved.

Note the mass of copper(1) oxide formula unit 143.091 what is the mass of 8.250 moles of Cu2O
Answer:
The mass of 8.250 moles of Cu2O is 1180.5g
Explanation:
HOW TO CALCULATE MASS OF A SUBSTANCE:
The mass of a substance can be calculated by multiplying the number of moles in the substance by its molar mass as follows:Mass (g) = no. of moles (mol) × molar mass (g/mol)
Molar mass of copper (I) oxide (Cu2O) = 63.5(2) + 16 = 143.09 g/molMass of Cu2O = 8.250 mol × 143.09 g/mol
Mass of Cu2O = 1180.5 g
Therefore, the mass of 8.250 moles of Cu2O is 1180.5 g.

Explanation:
A sugar crystal contains approximately 1.4×1017 sucrose (C12H22O11) molecules. What is its mass in milligrams? Express using 2 sig figs
Answer:
Our process would be just turning the molecules of sucrose to the moles by dividing using Avogadro's number (6.02 x 10^23), which will give us the moles we need. In order to find the mass of the sucrose, you have to multiply the moles by the molar mass of sucrose in order to find the mass, and then multiply by it 1000 to change it to mg.
Here are the formulas:
Number of moles = Number of molecules / Avogadro's number
Mass = Moles x Molar mass
Number of moles = (1.4 x 10^17) / (6.02 x 10^23) = 2.3255814 x 10^-7 moles
Now that we have the moles, we can multiply them by Sucrose's molar mass, which can be calculated by using the masses listed in the periodic table.
Carbon's Molar Mass = 12g/mol (There are 12 atoms of Carbon in sucrose)
Hydrogen's Molar mass = 1.01g/mol (22 atoms of Hydrogen in sucrose)
Oxygen's Molar mass = 16g/mol (11 atoms of oxygen in sucrose)
Now we just add them together:
((12)x(12)) + ((1.01)x(22)) + ((16)x(11)) = 342.22g/mol is the molar mass of Sucrose
Now back to the question, you multiply the moles of sucrose by its molar mass to get the mass in grams
(2.3255814 x 10^-7) x (342.22) = 0.0000796 grams
Now to get it in milligrams, you multiply the answer above by 1000
0.0000796 x 1000 = 0.079 mg (already in 2 sig figs)
Therefore there are 0.079 milligrams of sucrose in the sugar crystal.
The mass of sucrose molecules is 0.079 milligrams .
How is mass calculated from number of molecules?To calculate mass of a substance wherein number of molecules is given, initially number of moles is obtained.
number of moles= number of molecules/Avogadro's number
=1.4×10¹⁷/6.022×10²³
=2.234×10[tex]^-7[/tex]
Now the mass is calculated by multiplying number of moles into molar mass of sucrose
=2.234×10[tex]^-7[/tex]×342.22
=795.31 ×10[tex]^-7[/tex] g
=0.079 mg.
The mole concept is a convenient method for expression of amount of substance in chemical applications.It is mainly focused on the quantity of mole which is a count of large number of particles.One mole of any substance is equal to the Avogadro's number .
It is useful for measuring products of chemical reaction. It is the basis of stoichiometry and expresses amount of reactants and products which are formed and consumed during the course of chemical reaction.

1. You learned that waves in the ocean, sound waves, and light waves all have certain things in common. They all carry energy. The velocity, frequency, and wavelength of each is connected by the same equation. Which type of wave would you most want to learn more about? Why does it interest you? What would you want to find out about it? Write your answers in 2-3 paragraphs. (10 points) Would you like to know more about how waves in the ocean move, how sound travels, or how light works?
2. If you could somehow travel inside an atom and look around, what part of the atom would you want to look at? Why? What would you want to understand better as a result of your "travels"? Write your answers in 2-3 paragraphs. (10 points) Do electrons or the nucleus interest you more? What questions do you still have about how an atom works?
Answer:
Explanation:
1) I personally would want to learn more about how the waves in the ocean move. About what causes high tide. What causes low tide. Why some waves are big and some small.
I know it has something to do with the gravitational pull of the moon. But that is as far as my knowledge extends on the subject. I have always been fascinated with the secrets of the ocean and the secrets of space. To me learning, this is a little of both.
2) The nature of the interaction between neutrons and protons in the atomic nucleus, which binds the nucleons together, is the biggest wonder in the inside of the atom that I would like to really know. Protons have a positive charge, but neutrons do not. What form of interaction between a charged particle and an uncharged particle is possible? That is what I expect to learn more about as a result of my explorations into the inner workings of the atom.
The inside of the atom is made up of the nucleus and electrons that travel about in orbits. The nucleus is made up of protons and neutrons. Electrons have a negative charge, protons have a positive charge, and neutrons have none. The nucleus is held together by electrostatic interaction between electrons and protons. The majority of the mass of an atom is made up of protons and neutrons.
I'm interested in finding out more about ocean waves travel. regarding the reason for high tide. what brings on a low tide. Although some waves become also large while others are smaller.
What are ocean waves?Ocean waves seem to be alterations to the ocean's surface. They could be produced by water being moved by the wind, gravity, as well as other forces.
What are waves?A disturbance that moves from one place to another across a medium has been referred to as a wave. As an illustration of a wave, think of a sinuous wave.
Personally, I'm interested in finding out more about ocean waves travel. regarding the reason for high tide. what brings on a low tide. Although some waves become also large while others are smaller I'm certain that the moon's gravitational force is somehow implicated. Because that is basically the extent of my expertise on the matter. The mysteries of the water and the mysteries of space have always interested me. I'm still learning, so this combines a bit of both.The largest enigma in the interior of the atom something I would really like to understand is the nature of the connection involving neutrons as well as protons in the nucleus of an atom, which holds the nucleons together. Neutrons just don't have a positive electrical charge, whereas protons do. What kind of interactions is conceivable between charged as well as uncharged particles. Through my investigations into the internal workings of the atom, I hope to understand more about it.
