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.

What is the molarity of a sodium chloride solution that has 2.0 mol of
sodium chloride dissolved in 0.25 L of water? Answer to two
significant figures.
Answer:
[tex]\boxed {\boxed {\sf 8.0 \ M \ NaCl}}[/tex]
Explanation:
Molarity is a measure of concentration in moles per liter, therefore the formula is:
[tex]molarity= \frac{moles \ of \ solute}{lites \ of \ solution}[/tex]
There are 2.0 moles of solute or sodium chloride dissolved in 0.25 liters of water or solution.
moles of solute = 2.0 mol NaCl liters of solution = 0.25 LSubstitute these values into the formula.
[tex]molarity= \frac{ 2.0 \ mol \ NaCl}{0.25 \ L}[/tex]
Divide.
[tex]molarity=8 \ mol \ NaCl / L[/tex]
Molarity is measured in molars or M. 1 molar is equal to 1 mole per liter, so our answer is equal to 8 molars.
[tex]molarity= 8 \ M \ NaCl[/tex]
The original measurements of moles and liters have 2 significant figures, so our answer must have the same. For the number we calculated, that is the tenths place. There are no numbers to round, so we add a 0 in the tenths place.
[tex]molarity= 8.0 \ M \ NaCl[/tex]
The molarity of the solution is 8.0 M NaCl.

What mass of helium gas (in g) occupies 15.3 L at STP?
Answer:
[tex]\boxed {\boxed {\sf 2.73 \ g \ He}}[/tex]
Explanation:
We are asked to find the mass of helium gas given a volume.
1. Convert Liters to Moles1 mole of any gas occupies a volume of 22.4 liters. So, 1 mole of helium gas contains 22.4 liters of helium. Create a ratio using this information.
[tex]\frac {1 \ mol \ He }{ 22.4 \ L \ He}[/tex]
We are converting 15.3 liters of gas to moles, so we multiply by that value.
[tex]15.3 \ L \ He *\frac {1 \ mol \ He }{ 22.4 \ L \ He}[/tex]
The units of liters of helium (L He) cancel.
[tex]15.3 *\frac {1 \ mol \ He }{ 22.4}[/tex]
[tex]\frac {15.3}{22.4} \ mol \ He[/tex]
[tex]0.6830357143 \ mol \ He[/tex]
2. Convert Moles to GramsThe molar mass is the mass of 1 mole of a substance. These values are found on the Periodic Table as atomic masses, but the units are grams per moles. Look up the molar mass of helium.
He: 4.0026 g/molCreate another ratio using the molar mass.
[tex]\frac {4.0026 \ g \ He}{1 \ mol \ He}[/tex]
Multiply by the number of moles we calculated.
[tex]0.6830357143 \ mol \ He *\frac {4.0026 \ g \ He}{1 \ mol \ He}[/tex]
The units of moles of helium (mol He) cancel.
[tex]0.6830357143*\frac {4.0026 \ g \ He}{1 }[/tex]
[tex]2.73391875 \ g \ He[/tex]
3. RoundThe original measurement of volume has 3 significant figures, so our answer must have the same.
For the number we calculated, that is the hundredths place.
The 3 in the thousandths place to the right (2.73391875) tells us to leave the 3 in the hundredths place (2.73391875).
[tex]2.73 \ g \ He[/tex]

Que. 1. Gallium has 2 naturally occuring Isotopes with mass numbers 69 & 71 respectively. What is the percentage abundance of both Isotopes if their relative atomic mass is equal to 70.59 Amu (Atomic mass Unit)
Isotopes are atoms of the same element that have different masses. The relative atomic mass (am) is a weighted average that takes into account the abundance of each isotope. We can calculate the relative atomic mass using the following expression.
[tex]am = \frac{\Sigma m_i \times ab_i}{100}[/tex]
where,
mi: mass of each isotopeabi: percent abundance of each isotopeFor Gallium,
[tex]70.59 amu = \frac{69 amu\ x + 71 amu\ y}{100}[/tex] [1]
where "x" and "y" are the unknown abundances.
We also know that the sum of both abundances must be 100%.
x + y = 100
y = 100 - x [2]
If we replace [2] in [1], we get
[tex]70.59 amu = \frac{69 amu\ x + 71 amu\ (100-x)}{100} \\7059 amu = -2 amu\ x + 7100amu \\x = 20.5[/tex]
Then, in [2]
y = 100 - x = 100 - 20.5 = 79.5
In conclusion, Ga-69 has an abundance of 20.5% and Ga-71 has an abundance of 79.5%.

My theoretical yield is 14 grams of water. I actually produced 6 grams of water. What is my percent yield?
Answer:
Pertaining to the interrogate, the answer to such is acknowledged and henceforth disseminated as 43.0%
Explanation:
To evaluate such, the following must be comprehended:
Percent Yield Calculator:
% Yield = (What You Actually Got / What You Should Theoretically Get) * 100
The following variables may be denoted, as stated within the interrogate:
Yielded/Produced: 6 grams.
Theoretical Yield: 14 grams.
(6 g/14 g) * 100 = 42.8571428571
*Grams measurement cancels*
42.8 ==> 43.0%
Thus, if rounded to the nearest tenth, the percent yield is equivalent to 43.0%.

If you start with 4.5 moles of aluminum and 6.5 moles of copper chloride to make aluminum chloride and copper, what is the limiting reagent?
2Al + 3CuCl -> 2AlCl3 + 3Cu
Answer:
The limiting reagent is CuCl
Explanation:
The initial number of moles of aluminum, Al = 4.5 moles
The number of moles of copper, Cu = 6.5 moles
The given chemical reaction is presented as follows;
2Al + 3CuCl → 2AlCl₃ + 3Cu
Therefore, we have, 2 moles of aluminum combine with 3 moles of CuCl produces 2 moles of AlCl₃ and 3 moles of Cu
1 mole of Al will combine with (3/2) moles of CuCl,
Therefore, 4.5 moles of Al will combine with (4.5 × (3/2) = 6.75) 6.75 moles of CuCl
Given that the number of moles of CuCl present is only 6.5 moles which is less than the 6.75 moles required to combine with the 4.5 moles, the 6.5 moles of CuCl limits the amount of AlCl₃ and Cu produced, and therefore the CuCl is the limiting reagent.
