Answer:
c
Explanation:
During the "Third Quarter" phase, Earth sees more than half of the moon's surface. The correct option is B.
What is Waxing Gibbous and Waning Crescent?Waxing Gibbous and Waning Crescent are two phases of the Moon.
Waxing Gibbous is a phase of the Moon that occurs after the First Quarter phase and before the Full Moon phase. During this phase, the illuminated portion of the Moon is greater than half but less than fully illuminated, meaning it appears to be a "bulging" shape. The term "waxing" means that the illuminated portion of the Moon is increasing in size.
The Waning Crescent is a phase of the Moon that occurs after the Third Quarter phase and before the New Moon phase. During this phase, the illuminated portion of the Moon is less than half and decreasing in size. The term "waning" means that the illuminated portion of the Moon is decreasing in size. The crescent shape refers to the thin sliver of illuminated portion of the Moon that is visible during this phase.
Here in this question,
During the First Quarter phase, the right half of the Moon's surface is visible from Earth.
During the Third Quarter phase, the left half of the Moon's surface is visible from Earth.
During the Waxing Gibbous phase, more than half of the Moon's surface is visible, but Earth does not see more than half.
During the Waning Crescent phase, less than half of the Moon's surface is visible, and Earth does not see more than half.
Therefore, Option B i.e third quarter is correct.

ch question carries 2 mark. Time Remaining : 00 : 46 : 33 Some oxides are given below. (i)Na2O (ii)NO2 (iii) CO2 (iv) MgO a) Which are the basic oxides among these? b) What is the name of the aqueous solution of CO2 ?
The basic oxide is an oxide-forming a base solution.
These oxides are mainly from group 1 alkaline and group 2-alkaline earth
If this oxide is dissolved in water it will form an alkaline solution
LO + H₂O --> L(OH)₂ ---> alkaline earth
L₂O + H₂O --> LOH --> alkaline
So the basic oxides : Na₂O and MgO
Na₂O + H₂O --> NaOH (sodium hydroxide, strong base)
MgO + H₂O --> Mg(OH)₂ (magnesium hydroxide, strong base)
The aqueous solution of CO₂ , obtained by dissolving CO₂ in water
CO₂ + H₂O --> H₂CO₃ (carbonic acid)
In general, basic oxide is obtained from metal oxide, while acid oxide is obtained from non-metal oxide

An atom of tin has an atomic number of 50 and a mass number of 119. How many protons, electrons, and neutrons are found in one neutral atom of tin?
Answer:
50
Explanation:
atomic number is equivalent to it's protons, electrons and neutrons in a neutral atom
The atomic number is reminiscent of its protons, electrons, and neutrons during a neutral atom. When A particle of an atom contains 26 protons, 23 electrons, and also 56 neutrons.
Protons, Electrons, and NeutronsWhen Every atom of tin has 50 protons in its nucleus. And there'll be 50 electrons around a neutral atom of tin. the quantity of neutrons varies because there are different isotopes of tin. Tin is interesting in this it's the element with the best number of stable isotopes of all the weather within the table. it's 10 stable isotopes, and that they are tin-112 (62 neutrons), tin-114 (64 neutrons), tin-115 (65 neutrons), tin-116 (66 neutrons), tin-117, (67 neutrons), tin-118, (68 neutrons), tin-119, (69 neutrons), The tin-120 (70 neutrons), tin-122 (72 neutrons), and also tin-124 (74 neutrons). There are other isotopes of tin starting from tin-99 to tin-137, and also the neutron count in any one of them are often found by subtracting the number of tin (which is 50, or the number of protons within the nucleus), from the mass unit of the isotope. for example, if we have an interest in tin-121, it's 121 minus 50 or 71 neutrons in it.
Thus the solution is 50

Jason is designing a computer model that shows the structure of different molecules. His model uses spheres to represent the atoms and lines to represent bonds. His program calculates the correct angle of the bonds and allows the user to rotate the molecule to see it in three dimensions. Which change could Jason make to his program to make the model more like a real molecule?
Answer:
Explanation:
The computer model that is being described seems pretty accurate, the only change I would consider making would be a zoom in/out feature that allows the user to zoom-in in order to see the protons and electrons that make up the atoms which ultimately make up the molecule. Mainly since they are also a very important part of the molecules' structure and final composition and can be a vital piece of data, especially being able to visualize it.

Explanation:
Consider the reactions C2H4(g) + 2O2(g) → 2CO(g) + 2H2O(g) ∆H = −758 kJ mol−1 2C(s) + 2H2(g) → C2H4(g) ∆H = +52 kJ mol−1 H2(g) + O2(g) → H2O(g) ∆H = −242 kJ mol−1 The enthalpy of formation of carbon monoxide is A −111 kJ mol−1 B −163 kJ mol−1 C −222 kJ mol−1 D -464 kJ mol−1
C2H4(g) + 2O2(g) → 2CO(g) + 2H2O(g) ∆H1 = −758 kJ mol−1 ....1)
2C(s) + 2H2(g) → C2H4(g) ∆H2 = +52 kJ mol−1 ....2)
H2(g) + O2(g) → H2O(g) ∆H3 = −242 kJ mol−1 ....3)
Now, enthalpy of formation of carbon monoxide is given by :
∆H = ∆H1 + ∆H2 - ∆H3
∆H = ( -758 + 52 - ( -242 ) ) kJ mol−1
∆H = −464 kJ mol−1
Therefore, the enthalpy of formation of carbon monoxide is -464 kJ mol−1.
Hence, this is the required solution.

What is the primary reason why elements form compounds?
Answer:
To gain stability
Explanation:
If the outermost shell is not completely filled with electrons, the element has one of the three options: gaining electrons, losing electrons or sharing electrons. By gaining or losing electrons, ionic compounds are produced. Sharing of electrons results in the formation of covalent compounds.

An orbital that could never exist according to the quantum description of the atom is
Answer:
d. 3f
Explanation:
An orbital in chemistry is defined as the wave function that defines the position of electrons in an atom.
There are four types of orbitals that include s, p, d, and f. On the basis of the quantum description, 3f orbital does not exist because in the third energy level only three sublevels are present that are s, p, and d that can hold a maximum of 18 electrons.
Hence, the correct answer is "d.3f".
For the 3 principal orbitals, f suborbital has not been possible. Thus the orbital that could never exist according to the quantum description of the atom is 3f. Thus the correct option is d.
Quantum mechanics helps in the determination of the electron address. The electron address has been given by the 4 quantum numbers namely,
Principal quantum numberAzimuthal quantum numberMagnetic quantum numberSpin quantum numberThe principal quantum number gives the information to the orbital, and the azimuthal quantum number gives the information of the subshell.
The orbitals have been formed by the mixing of the bonding and anti-bonding orbital. The mixing of the 3 orbital has resulted in the 3 suborbital namely s, p, and d.
Thus for the 3 principal orbitals, f suborbital has not been possible. Thus the orbital that could never exist according to the quantum description of the atom is 3f. Thus the correct option is d.
