Which pair of orbitals has the same shape?
Your answer:
2s and 2p
2s and 1s
3p and 3d
more than one is correct
Answers
Answer:
2s and 1s
Explanation:
The s orbital is spherically symmetrical. The wave function depends on the distance from the nucleus and not on the direction.
The 2s and 1s orbitals are of the same shape only that the 2s orbital is larger than the 1s orbital.
The images of these orbitals are shown in the image attached.
The pair "2s and 1s" has the same shape. A complete explanation is below.
Throughout Mendeleev's table, the "s" orbital has a sphere as well as round symmetry. This same wave function would be determined by the difference again from the nucleus rather than the directions.These same 2s, as well as 1s orbitals, are approximately identical in form, with the exception being the 2s orbital appears bigger than the whole 1s orbital.
Thus the above alternative i.e., "option B" is appropriate.

Which relationship explains how the water can boil at room temperature?
A Lower air pressure results in a lower boiling point
B. Lower air temperature results in a lower boiling point
C. Lower air pressure results in a higher boiling point
D. Lower at temperature results in a higher boiling point
Answers
Answer:
Option A.
Lower air pressure results in a lower boiling point
Explanation:
This is because in an open system, the lower the pressure the lesser the energy that will be required for boiling point. The is little or no collision of air molecules with the surface of the liquid
But if there is increase in pressure, more energy will be required to get to boiling point because there will be strong collision between air molecules and surface of the liquid.

why is true about electron dot diagrams
Answers
Answer: The correct answer is the option: B. An element with eight valence electrons is chemically unstable.
Explanation:
Hello! Let's solve this!
We will analyze each of the options:
A. The group number of the element provides a clue to the number of valence electrons: it is correct, since it provides the number of valence electrons.
B. An element with eight valence electrons is chemically unstable: this is not correct, since elements with eight electrons in the valence shell cannot react because they already have the last complete shell. Therefore, they are chemically stable.
C. The points must be placed one at a time on each side of the chemical symbol: it is correct, because that is the way to make the point diagram.
D. An atom is chemically stable if all the points are paired: this is correct since this verifies that the point diagram has been done well.
We conclude that the correct answer is the option: B. An element with eight valence electrons is chemically unstable.

How is energy transferred when..
Answers
Answer:
Number 1 is Conduction. Number 2 is Radiation. Number 3 is Convection. i think if thats how im supposed to word it...
Explanation:
Answer:
1. Each collision passes energy from particles moving quickly to particles moving slowly. In this way, the energy spreads throughout the pan and finally reaches the handle. This process is called conduction. Conduction is the transfer of heat that happens when particles collide with each other.
2. A fire spreads by transferring heat energy in three ways: Radiation, Convection, and Conduction. Radiation refers to the emission of energy in rays or waves. Heat moves through space as energy waves. ... This is the reason that when facing the fire, only the front is warmed.
3. The ways in which energy is dissipated depends on the system: ... for a tumble dryer, the electrical work is transferred into useful internal (thermal) energy which helps to dry clothes and energy is dissipated wastefully by sound waves which cause a rise in the internal energy store (temperature) of the surroundings.

The reaction between nitrogen and hydrogen to produce ammonia is described by the equilibrium reaction:
3H2 + N2 = 2 NH 3 3H2
What substances are present in the reaction mixture when equilibrium has been obtained.
Answers
Answer:
Explanation:
The formation of ammonia that occurred by the reaction of nitrogen and ammonia is expressed as:
[tex]3H_{2(g)} + N_{2(g)}[/tex] ⇄ [tex]2NH_{3(g)}[/tex]
where;
The reactants are:
Hydrogen and nitrogen
The product is ammonia.
For the reaction, the equilibrium constant can be expressed as:
[tex]K = \dfrac{[product]}{[reactants]}[/tex]
[tex]K = \dfrac{[NH_3]^2}{[N_2]^3[H_2]^3}[/tex]
From the equilibrium constant conditions, the formation of ammonia and its decomposition due to its reversible reaction back to hydrogen and nitrogen are equal. It implies that the rate of the forward reaction is also equal to that of the backward reaction.
Thus, during when equilibrium is obtained;
Hydrogen, Nitrogen, and Ammonia are present.
Rubidium has two common isotopes, 85Rb and 87Rb. If the abundance of 85Rb is 72.2% and the abundance of 87Rb is 27.8%, what is the average atomic mass of rubidium
Answers
Answer:
85.556 amu
Explanation:
From the question given above, the following data were:
Isotope A (85–Rb):
Mass of A = 85 amu
Abundance (A%) = 72.2%
Isotope B (87–Rb):
Mass of B = 87 amu
Abundance (B%) = 27.8%
Average Atomic mass of rubidium =?
The average atomic mass of rubidium can be obtained as follow:
AVERAGE = [(Mass of A × A%)/100] + [(Mass of B × B%)/100)]
AVERAGE = [(85 × 72.2)/100] + [(87 × 27.8)/100]
= 61.37 + 24.186
= 85.556 amu
Therefore, the average atomic mass of rubidium is 85.555 amu

Answers
Answer:
Protista
Explanation:
The organisms would probably belong to the kingdom Protista.
Organisms in the Protist kingdom are unicellular and animal-like. They possess all the attributes of animals except the fact that they are unicellular. They are different from fungi in being mobile and being able to ingest their foods. Unlike monera, protists are eukaryotic and unlike plants, most protists are heterotrophic (except euglena).
The cells of protists possess nuclei and locomotive structures such as pseudopodia (e. amoeba), cilia (e.g paramecium), and flagella (e.g euglena).
Hence, the organisms seen on the prepared slides of pond of water would probably belong to the Protist kingdom.
These organisms belong to the Kingdom known as Protista.
Protists are referred to eukaryotes which are mostly unicellular(single-celled) and examples include
AmoebaFlagellates CiliatesSporozoans.They are also microscopic and can't be seen with the naked eyes. In this
scenario, we were told that the pond contains single-celled organisms which
have cilia and flagella . This depicts that the organisms fall under the
kingdom Protista.

An ion of an element can have the same ________ as another element.
Answers
Answer:
Number of electrons.
Explanation:
I hope this helps.
An ion is said to be the molecule or the atom that has the presence of a net electrical charge over them. An ion can have the same protons as the other elemental atom. Thus, option A is correct.
What is an ion?An ion is defined by the atom or the molecule with an electrical charge of positive and negative on them due to the gain or the loss of the electron in their orbits for the bond formations and stability.
The ions of the atom have the same number of protons in their nucleus but the number of the electrons varies as they looses and gain electron to acquire the positive and the negative charge over them.
The presence of the extra or less electron in the orbit or the shell of the atom makes them reactive and allows the electrostatic attraction between them for the bond formation.
Therefore, in option A. the protons are the same in an ion.
