The particle that is labeled with a question mark (?) in the diagram is Quarks
Quarks are elementary particles and fundamental constituents of matter. They are considered the smallest known particles that make up protons and neutrons, which are the building blocks of atomic nuclei. Quarks are classified as fermions, which means they follow the rules of quantum mechanics and obey the Pauli exclusion principle.
There are six known types, or flavors, of quarks: up (u), down (d), charm (c), strange (s), top (t), and bottom (b). Each quark flavor has a unique set of properties, including mass, electric charge, and the way they interact with other particles through the strong nuclear force. The up and down quarks are the lightest and most common, while the top quark is the heaviest.
One notable property of quarks is that they possess a fractional electric charge. The up quark has a charge of +2/3 (e/3), while the down quark has a charge of -1/3 (-e/3), where "e" represents the elementary charge carried by an electron. Quarks are never found in isolation due to the confinement principle, which means they are always bound together in composite particles called hadrons.
Quarks interact through the strong nuclear force, which is mediated by particles called gluons. This force binds quarks together to form protons and neutrons, and also governs the interactions within atomic nuclei.

Alveolar air (a mixture of nitrogen, oxygen, and carbon dioxide) has a total pressure of 0.998 atm. If the partial pressure of oxygen gas is 0.198 atm and the partial pressure of nitrogen gas is 0.770 atm, what is the partial pressure of carbon dioxide in millimeters of mercury?
Answers
Answer:
22.8 mmHg
Explanation:
According to Dalton's law of partial pressures, the total pressure of a mixture of gases is obtained as the sum of the partial pressures if all the individual gases present in the mixture.
Since the total pressure of gases in the mixture is 0.998 atm, the partial pressure of carbon dioxide is;
PCO2 = [Ptotal - (PO2+ PN2)]
Hence;
PCO2 = [0.998 - (0.198 + 0.770)]
PCO2 = 0.03
Since
1 atm = 760 mmHg
0.03 atm = 0.03 × 760 /1
=22.8 mmHg

O c. It must have an electron that has jumped to a higher energy

O d. It must have different numbers of protons and electrons
Answers
Answer:
I think it’s D.
Explanation:
An atom does not have a different amount of protons and electrons if there is no change... During ionisation you either lose or gain electrons, so when that happens (a change) it will have a different number.

Assume that an object has been placed in the pan of a triple beam balance. The
scales of the balance are shown below. What is the mass of the object?
Answers
Answer:
190.4 g
Explanation:
To obtain the mass of the object, we must be able to obtain the reading of the triple beam balance.
Thus, the reading of the balance can be obtained by simply adding the various values as indicated by the pointer in each scale.
This can be obtained as follow:
Scale 1 = 90 g
Scale 2 = 100 g
Scale 3 = 0.4 g
Reading of the balance = Scale 1 + Scale 2 + Scale 3
Reading of the balance = 90 + 100 + 0.4
Reading of the balance = 190.4 g
Thus, the mass of the object as indicated by the triple beam balance is 190.4 g.

23. A 54-gram sample of an unknown material has a volume equal to 20 cm'. Based on its density,
could the sample be aluminum? Explain.
Answers
Answer:
The given sample is aluminum.
Explanation:
Given data:
Mass of unknown sample = 54 g
Volume of given sample = 20cm³
Is sample is Al = ?
Solution:
In order to solve this problem we must know the density of Al from literature.
density of Al = 2.7 g/cm³
Now we will calculate the density of given unknown sample.
d = m/v
d = 54 g/ 20cm³
d = 2.7 g/cm³
Thus given sample is aluminum.

Ammonium nitrate (NH4NO3) is a common component of fertilizer because it is a great source of two nitrogen-containing ions that easily dissolve into water. A large batch of this liquid fertilizer is made by adding 2.13 pounds of ammonium nitrate to 26.00 gallons of water. What is the molarity of this solution? (Hint: 1 lb. = 454 g and 1 gal. = 3.79 L.)
Answers
Answer:
0.123 M
Explanation:
Molarity, which is molar concentration can be calculated by using the formula;
Molarity = number of moles (n) / Volume (V)
Number of moles of NH4NO3 can be calculated by using;
Mole = mass (M) / Molar mass (MM)
Since atomic mass of N= 14, H=1, O=16
Molar mass of NH4NO3 = 14 + 1(4) + 14 + 16(3)
= 14 + 4 + 14 + 48
= 80g/mol
1 pounds = 454g
2.13 pounds= 2.13 × 454 g
= 967.02g
Hence; mole of NH4NO3 = 967.02/80
= 12.09moles
Molarity of NH4NO3 in water (solution) = number of moles of NH4NO3 ÷ volume of water
1 gallon = 3.79Litres
26gallons = 26 × 3.79 litres
= 98.54 Litres
Therefore, Molarity = 12.09/98.54
Molarity of NH4NO3 solution = 0.1226
= 0.123M or mol/L

What is an element?An element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.
