Kilograms are the largest unit among the options listed.
The metric system is a decimal-based system of measurement widely used around the world. It provides a standardized and convenient way to express measurements by utilizing prefixes that represent powers of 10.
In the metric system, the base unit for measuring mass is the gram (g). The gram is a relatively small unit, and to express larger or smaller masses, prefixes are added to the base unit. Here are some commonly used metric prefixes for mass.
The largest measurement among the options provided is kilograms (kg). Kilograms are larger units of measurement compared to grams (g), milligrams (mg), and centigrams (cg). The metric system follows a decimal-based system, where each unit is 10 times larger or smaller than the adjacent unit.
1 kilogram (kg) is equal to 1,000 grams (g), 1,000,000 milligrams (mg), and 10,000 centigrams (cg). Therefore, kilograms are the largest unit among the options listed.

what does an atomic emission spectrum look like if the electrons energy levels in an atom were not quantizied
a. lines would be shifted into the ultraviole region
b. there would be fewer lines
c. there will be more lines
d. the spectrum would be constnuous
Answer: The spectrum would be continuous
Explanation:
Atomic transitions allow us to find that the correct answer to what would happen if there was no quantization is:
d. the spectrum would be continous
In the models of atoms the correct explanation for the energy was given by Planck, by establishing that the energy of an electron is:
E = h ν
Where E is the energy, h the Planck constant and ν the frequency.
Therefore a transition occurs as the jump of an electron from one level to another
ΔE = E₂ - E₁
In all atomic models the levels are discrete, so the jumps are also discrete.
If the levels were continuous, the energy difference between the lines disappears and we have a continuous emission spectrum.
Let's review the different answers:
a. False. The lines disappear
b. False. This for if the separation between levels increases, which is the opposite process to the one analyzed.
c. False. The lines disappear
d) True. The spectrum is a continuum without any separation.
In conclusion, using the atomic transitions we find that the correct answer for what would happen if there was no quantization is:
d. the spectrum would be constnuous

Answer:
PET works by using a scanning device (a machine with a large hole at its center) to detect photons (subatomic particles) emitted by a radionuclide in the organ or tissue being examined.
Newer technology combines PET and CT into one scanner, known as PET/CT. PET/CT shows particular promise in the diagnosis and treatment of lung cancer, evaluating epilepsy, Alzheimer's disease and coronary artery disease.

What is the percent of Li in
Li3N?
(Li = 6.94 amu, N = 14.01 amu)
Answer:
The percentage by mass of lithium in one mole of Li₃N is approximately 59.78%
Explanation:
The given compound is Li₃N
The atomic mass of lithium, Li = 6.94 amu
The atomic mass of nitrogen, N = 14.01 amu
Therefore by definition, we have;
The mass of one mole of lithium, Li = 6.94 g
The mass of one mole of nitrogen, N = 14.01 g
One molecule of Li₃N contains 3 atoms of lithium, Li and 1 atom of nitrogen, N
The mass of one mole of Li₃N = The molar mass of Li₃N = 3 × The mass of one mole of lithium + The mass of one mole of nitrogen
∴ The mass of one mole of Li₃N = 3 × 6.94 g + 14.01 g = 34.83 g
The percentage by mass of lithium, Li, in one mole of Li₃N = 3×6.94/(34.83) × 100 ≈ 59.78%
The percentage by mass of lithium in one mole of Li₃N ≈ 59.78%.

Develop a relationship (in the form of a single sentence or equation) that can predict the charge based on the number and types of particle.
Answer:
The charge of an atom is determined by the ratio of protons to electrons
Explanation:
I hope this helps!!
A relationship showing the charge on an atom can be expressed as ;
Types of particle are protons and electrons Charge on atom = ( Number of protons - Number of electrons )The charge an atom posses depends on the particles/components of the atom which are protons and electrons. The protons are positively charged ions that are present in the nucleus of an atom while electrons are negatively charge ions present in the outer shell of an atom.
To predict the charge on an atom we will determine the difference between the number of protons and the number of electrons present in an atom.
Hence we can conclude that the relationship can be expressed as Types of particle are protons and electrons , Charge on atom = ( Number of protons - Number of electrons )

Rate of consumption of N₂ = - 1.25 x 10⁻⁴
Further explanationThe reaction rate (v) shows the change in the concentration per unit time.
[tex]\tt rate=\dfrac{concentration(M)}{time(s)}[/tex]
The rate reaction for Haber Bosch :
N₂(g)+3H₂(g)⇒2NH₃(g)
From equation, mol ratio N₂ : NH₃ = 1 : 2, so
the rate of formation of ammonia = 2 x the rate of consumption of nitrogen.
Given
the rate of formation of ammonia gas : 2.5x10⁻⁴ M/s
the rate of consumption of nitrogen :
[tex]\tt \dfrac{2.5\times 10^{-4}}{2}=1.25\times 10^{-4}[/tex]
The sign negative for consumption : -1.25 x 10⁻⁴ M/s
or we can use another way:
Rate of formation of NH₃ = reaction rate x coefficient of NH₃
2.5 x 10⁻⁴ = reaction rate x 2
reaction rate = 1.25 x 10⁻⁴
Rate of consumption of N₂ = reaction rate x coefficient of N₂
Rate of consumption of N₂ = 1.25 x 10⁻⁴ x 1
Rate of consumption of N₂ = 1.25 x 10⁻⁴

Explanation:
The reaction expression is given as:
2H₂O → 2H₂ + O₂
Given;
Number of moles of H₂O = 2.54moles
Unknown:
Number of moles of H₂ produced = ?
Solution:
To solve this problem, we use the concept of mole comparison. Now from the reaction expression, we know that;
2 mole of H₂O will produce 2 mole of H₂
2.54 mole of H₂O will then produce 2.54mole of H₂
A boy swings a rubber ball attached to a string over his head in a horizontal, circular path. The piece of string is 1.15 m long and the ball makes 137 complete turns each minute. What is the tangential velocity of the ball
Answer:
v = 16.49 m/s
Explanation:
Given that,
Length of the string, l = 1.15 m
The ball makes 137 complete turns each minute.
We know that, 1 turn = 6.28 rad
137 turns = 860.79 rad
1 min = 60 s
[tex]\omega=\dfrac{860.79\ rad}{60\ s}\\\\=14.34\ rad/s[/tex]
We need to find the tangential velocity of the ball. It can be given by
[tex]v=r\omega\\\\=1.15\times 14.34\\\\v=16.49\ m/s[/tex]
So, the tangential velocity of the ball is 16.49 m/s.

What type of ion would radium (88Ra) become when forming an ionic compound, and what would the oxidation number be?
A) a cation with a +2 charge
B) a cation with a -2 charge
C) an anion with a +1 charge
D) an anion with a -1 charge
Answer:
The correct option is A
Explanation:
Radium is an atom with the atomic number of 88. It is a metal found in group 2 of the periodic table; meaning that it has two valence electrons in it's outermost shell. As a metal that wants to form an ionic compound, radium would have to lose these two valence electrons to become a divalent positively charged cation (Ra²⁺). Thus, the correct option is A

Answer:
When sleeping the energy exhibited is Potential energy. When I wake up and I’m preparing for the day I use kinetic energy which is the energy exhibited during motion.
Eating before leaving the house means I used chemical energy for replenishment of nutrients to aid the performance of more activities for the day. The food eaten and the physical activities also give rise to thermal energy which is why we sweat.
