Answer:
The Buddha (also known as Siddhartha Gotama or Siddhārtha Gautama[note 3] or Buddha Shakyamuni) was a philosopher, mendicant, meditator, spiritual teacher, and religious leader who lived in Ancient India (c. 5th to 4th century BCE).[5][6][7][note 4] He is revered as the founder of the world religion of Buddhism, and worshipped by most Buddhist schools as the Enlightened One who has transcended Karma and escaped the cycle of birth and rebirth.[8][9][10] He taught for around 45 years and built a large following, both monastic and lay.[11] His teaching is based on his insight into duḥkha (typically translated as "suffering") and the end of dukkha – the state called Nibbāna or Nirvana.
The Buddha was born into an aristocratic family in the Shakya clan but eventually renounced lay life. According to Buddhist tradition, after several years of mendicancy, meditation, and asceticism, he awakened to understand the mechanism which keeps people trapped in the cycle of rebirth. The Buddha then traveled throughout the Ganges plain teaching and building a religious community. The Buddha taught a middle way between sensual indulgence and the severe asceticism found in the Indian śramaṇa movement.[12] He taught a spiritual path that included ethical training and meditative practices such as jhana and mindfulness. The Buddha also critiqued the practices of Brahmin priests, such as animal sacrifice.
A couple of centuries after his death he came to be known by the title Buddha, which means "Awakened One" or "Enlightened One".[13] Gautama's teachings were compiled by the Buddhist community in the Suttas, which contain his discourses, and the Vinaya, his codes for monastic practice. These were passed down in Middle-Indo Aryan dialects through an oral tradition.[14][15] Later generations composed additional texts, such as systematic treatises known as Abhidharma, biographies of the Buddha, collections of stories about the Buddha's past lives known as Jataka tales, and additional discourses, i.e, the Mahayana sutras.

If I start with 0.0350 L of a 12.0 M hydrochloric acid solution, and dilute it with water to a new volume of 1.20 L, what is the new concentration?
Answer:
0.35 M
Explanation:
Using the formula; C1V1 = C2V2
Where;
C1 = concentration of initial solution
C2 = concentration of final solution
V1 = volume of initial solution
V2 = volume of final solution
Based on this question, I start with 0.0350 L of a 12.0 M hydrochloric acid solution, and dilute it with water to a new volume of 1.20 L. This means that:
C1 = 12.0 M, V1 = 0.0350 L, V2 = 1.20 L, C2 = ?
Hence, C1V1 = C2V2
12 × 0.0350 = C2 × 1.20
0.42 = 1.2C2
C2 = 0.42/1.2
C2 = 0.35 M

Draw the Lewis structure with the lowest formal charges for ClF2+ . Include nonzero formal charges and lone pair electrons in the structure.
Answer:
See explanation
Explanation:
The formal charge is obtained from;
Formal Charge = Valence electrons on atom - [number of bonds - lone pair electrons]
The correct structure of ClF2+ is the structure attached to this answer (image obtained from quora) in which the formal charge on fluorine is zero and the formal charge on chlorine is + 1. This is the correct structure because the chlorine is more electronegative than fluorine as expected.
The Lewis structure is a representation that shows electrons' distribution around each of the atoms composing a molecule. In the attached files you will find the Lewis structure for ClF2+.
----------------------
The Lewis structure is a representation that shows electron pairs in bonds between the atoms that compose the molecule. It also shows the solitary electron pairs that remain for each atom.
Structure
There is always a central atom and terminal atoms.
The central atom is surrounded by the terminal ones.
The central atom forms many bonds with terminal atoms.
When the molecule is composed of many atoms of the same element and a single atom of a different element, this last one is the central atom, and the others are terminal ones.
Usually, hydrogen and oxygen atoms are terminal, and carbon atoms are central.
Usually, the electropositive atoms are central, while the electronegative atoms are terminal.
Bonds
Bonds between atoms might be represented either as points or using a line. Two points equal a single line.
A pair of electrons represent one single bond.
Electrons pairs that are not involved in the bond are placed around the belonging atom.
Electrons
When adding the valence electrons of each atom we get the total number of electrons in the molecule.
The valence value is the number of electrons placed in the last energetic level of the atom.
When drawing the Lewis structure of an ion, the entire structure is between square brackets, and the charge is written as an exponent in the upper right corner, outside the brackets.
So let us analyze the exposed example, ClF2+
1) Cl and F have 6 electron pairs and a single one. 7 electrons in total each.
2) Since there are two F and one Cl, then Cl is the central atom and F are the terminal ones.
3) Valence electrons: 7e⁻ F + 7e⁻ F + 7e⁻ Cl = 21 electrons
Since the ion has a possitive charge, there are 20 electrons.
4) Electron pairs:
Each F needs to form bonds with Cl. Each bond requires two electrons.
Since there are two bonds, four electrons are required.
The 16 remaining electrons must be placed as 8 solitary pairs. Each atom needs a maximum of 8 electrons.
Each F will get 3 pairs maximum to get the 8 e⁻.Cl will get 2 pairs to get the 8 e⁻.
5) The ion is between brackets, and the charge is written as an exponent in the upper right corner.
You will find the image in the attached files.

At what point on the rollercoaster is
the kinetic energy the highest?
A. point A
B. point B
C. point C
D. cannot be determined
with the information provided.
Answer:
Point C
Explanation:
Remember that kinetic energy is energy a object has when it's in motion so the higher the speed, the higher the kinetic energy is. In this case we have a roller coaster, as the roller coaster goes up the tracks it's kinetic energy is low because it slows down as it climbs to the top of the hill. Then as it sits on top of the hill it's kinetic energy is little to none before it goes down the hill because the roller coaster isn't in motion. As when the roller coaster goes down the hill it's speed increases meaning the kinetic energy increases which means option C or "point C" is your answer.

Based on the data given, the work function of sodium metal is equal to [tex]7.91 \times 10^{-19}\;Joules[/tex].
Given the following data:
Mass of an electron = [tex]9.11\times10^{-31}\;kg[/tex].Photo electric work function = 476 kJ/mol.Velocity of electrons = [tex]9.57\times10^{5}\;m/s[/tex]Avogadro constant = [tex]6.02 \times 10^{23}[/tex]

If 19.2 grams of O2 reacts with iron to form iron oxide how much iron was used in the reaction? use the equation 4Fe + 3O2 — 2Fe2O3 to help
Answer:
44.8g
Explanation:
The reaction equation is given as:
4Fe + 3O₂ → 2Fe₂O₃
Given:
Mass of O₂ = 19.2g
Unknown:
Amount of iron used =?
Solution:
To solve this problem, we adopt the mole concept.
Since we know the mass of O₂;
Number of moles = [tex]\frac{mass}{molar mass}[/tex]
Molar mass of O₂ = 2(16) = 32g/mol
Number of moles = [tex]\frac{19.2}{32}[/tex] = 0.6moles
From the balanced reaction equation;
4 moles of Fe will react with 3 moles of O₂
0.6moles of O₂ will react with [tex]\frac{0.6 x 4}{3}[/tex] = 0.8mole of Fe
Mass of Fe = number of moles x molar mass
= 0.8 x 56
= 44.8g

An object with the mass of 2300 g has a force of 6.2 Newton's applied to it. What is the resulting acceleration of the object?
Answer:
[tex]\boxed {\boxed {\sf a\approx 2.7 \ m/s^2}}[/tex]
Explanation:
Force is equal to mass times acceleration.
[tex]F=m*a[/tex]
By dividing both sides by m, we rearrange the formula for a (acceleration).
[tex]\frac{F}{m} =a[/tex]
The force is 6.2 Newtons, but we can convert the units to make the problem easier later on.
A Newton is equal to 1 kg*m/s², so 6.2 N is equal to 6.2 kg*m/s².The mass is 2300 grams, but we need to convert it to kilograms.
To convert grams to kilograms, divide by 1,0002300 g/1000= 2.3 kg[tex]F= 6.2 \ kg*m/s^2\\m=2.3 \ kg[/tex]
Substitute the values into the formula.
[tex]a=\frac{6.2 \ kg*m/s^2}{2.3 \ kg}[/tex]
Divide. Note that the kilograms or "kg" will cancel each other out (this is why we converted the units).
[tex]a=\frac{6.2 \ m/s^2}{2.3 \ }[/tex]
[tex]a=2.69565217 \ m/s^2[/tex]
Round to the nearest tenth. The 9 in the hundredth place tells us to round up to 2.7
[tex]a\approx 2.7 \ m/s^2[/tex]
The acceleration is about 2.7 meters per second squared.
