Quantum Mechanics relies on probability to say what region of space an electron ismostlikelyto occupy. In your own words, describe how this principle results in the shapes ofthe orbitals.
Answer:
Explanation:
Since electrons are particles that are in constant movement in a wave-like motion, is impossible to know exactly their position and velocity at all times. That's why instead of defining an orbit for them we define an atomic orbital, which is a location in space where the probability of finding an electron is high (therefore, is an electron dense zone). Since this zone has not defined limits (the wave function characterizing the orbital extend from the nucleus to infinity), the further we go from the nucleus the less dense this "cloud" is.
There is about a 90 percent probability of finding the electron within a sphere of radius 100 pm surrounding the nucleus. Thus, we can represent the 1 s orbital by drawing a boundary surface diagram that encloses about 90 percent of the total electron density in an orbital, and the shape of this orbital is a sphere.
The boundary surface diagrams of p orbitals, for example, will have the shape of two lobes on opposite sides of the nucleus, that means that within this two lobes we have a 90 percent probability of finding the electron, and so on.
hello, what’s the difference between oxidation and oxidising agents?
Answer:
An oxidising agent oxidises something else. Oxidation is loss of electrons (OIL RIG). That means that an oxidising agent takes electrons from that other substance.

Changes in which two characteristics can indicate a physical change?
A. Shape
B. Reactivity
O C. State
D. Flammability
Changes in shape and state are the two characteristics which indicate a physical change.
What are physical changes?Physical changes are defined as changes which affect only the form of a substance but not it's chemical composition. They are used to separate mixtures in to chemical components but cannot be used to separate compounds to simpler compounds.
Physical changes are always reversible using physical means and involve a change in the physical properties.Examples of physical changes include melting,boiling , change in texture, size,color,volume and density.Magnetism, crystallization, formation of alloys are all reversible and hence physical changes.
They involve only rearrangement of atoms and are often characterized to be changes which are reversible.

In the quantum mechanical model, what two words do they use to describe
particles?
Answer:
This question is incomplete
Explanation:
This question is incomplete but one can assume the answer from the definition of quantum mechanics. Quantum mechanics is the science that describes particles in nature at the atomic and subatomic particle (electron, proton and neutron) level. Thus it can be assumed that atoms and subatomic particles are used to broadly describe particles.

C. There are 26 different atoms that are used to form molecules, just like there are 26 different letters that are used to form words.
D. There are no rules for how letters combine to make words, just like there are no rules for how atoms combine to make molecules.
To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. The correct option is option A.
What is atom?
Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit. Atoms can make many different molecules, just like letters can make many different words.
In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron.
Therefore, the correct option is option A that is Atoms can make many different molecules, just like letters can make many different words.

In experiment B. the iron filings weighed 2.0g at the beginning of the experiment
and the iron sulphide produced weighed 2.8g.
Explain this increase in mass.
Explanation:
The increase in mass is because the iron fillings have combined with a sulfide to produce iron sulfide and so the mass will increase.
In such a reaction like this, the mass of the reactants must be conserved. By so doing, the mass of reactants and products must be the same.
When two substances combine together, their masses added up to that of the individual masses. This helps to conserve the mass.

A scientist is breeding orange butterflies in the laboratory she notices a white butterfly in the latest generation of animals she sequences the genome of this butterfly in notices a mutation in the genes that calls for pigment in the wings. Explain how this mutation would result in a white butterfly.
Answer:
See explanation
Explanation:
A gene mutation can be defined as a permanent change in the DNA sequence that composes a gene, resulting in the observation that the sequence differs from what is obtainable in most individuals that make up the population. Mutations range from a change in a single DNA building block (change in the sequence of base pairs) to changes in a large segment of a chromosome that includes multiple genes.
Mutation in the color of the wings of the housefly can be passed on to the next generation. If this trait enhances survival of the butterflies, the orange winged butterflies will eventual become extinct and become entirely replaced by the white winged butterflies. This implies that gene pool has been completely modified.
If same kind of mutation of pigmentation of wings is observed in the butterfly then they will result in a white butterfly.
What is mutation?If a gene of the DNA get damaged or changes in such a way that it also results in the changing of genetic message carried by that gene and this process is known by the name of mutation.
In the given question by breeding orange butterfly with a white butterfly in the latest generation of animals, notices a mutation in the genes that calls for pigment in the wings. If the mutation of pigmentation of wings is passed to the next generations with the same changes in the gene of DNA, then after some generation we would get white butterfly.
Hence, if the same changes observed in the mutation of pigmentation of wings then we get a white butterfly.

Polyacrylamide is used in manufacturing soft contact lenses. It consist of 50.69% carbon, 19.71% nitrogen, 7.09% hydrogen, and 22.51% oxygen. Calculate the empirical formula for polyacrylamide.
Answer: The empirical formula is [tex]C_3NH_5O[/tex].
Explanation:
If percentage are given then we are taking total mass is 100 grams.
So, the mass of each element is equal to the percentage given.
Mass of C = 50.69 g
Mass of N= 19.71 g
Mass of H = 7.09 g
Mass of O = 22.51 g
Step 1 : convert given masses into moles.
Moles of C = [tex]\frac{\text{ given mass of C}}{\text{ molar mass of C}}= \frac{50.69g}{12g/mole}=4.22moles[/tex]
Moles of N=[tex]\frac{\text{ given mass of N}}{\text{ molar mass of N}}= \frac{19.71g}{14g/mole}=1.41moles[/tex]
Moles of H=[tex]\frac{\text{ given mass of H}}{\text{ molar mass of H}}= \frac{7.09g}{1g/mole}=7.09moles[/tex]
Moles of O = [tex]\frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{22.51g}{16g/mole}=1.41moles[/tex]
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For C =[tex]\frac{4.22}{1.41}=3[/tex]
For N = [tex]\frac{1.41}{1.41}=1[/tex]
For H = [tex]\frac{7.09}{1.41}=5[/tex]
For O =[tex]\frac{1.41}{1.41}=1[/tex]
The ratio of C:N:H: O = 3:1:5:1
Hence the empirical formula is [tex]C_3NH_5O[/tex].
Which type of bond shares the electrons between two elements?
Answer:
Covalent Bonds
General Formulas and Concepts:
Different types of bondsExplanation:
We have 3 types of bonds: Polar Covalent, Nonpolar Covalent, and Ionic bonds.
Nonpolar Covalent bonds share the electrons equally between the compound.
Polar Covalent bonds do NOT share the electrons equally, but STILL SHARE the electrons; the electron tends to stay with the element with the stronger electron affinity and thus creates dipoles.
Ionic bonds DO NOT share electrons. The electrons are transferred to the respective elements.

find ionic compounds
Answer:
1:1
Explanation:
The ratio of metal cationic atom to non-metal anionic atom in the compound is 1:1.
This is an ionic compound.
This is because metal cationic atom has two valence electrons. Non-metal anionic oxygen has six valence electrons Calcium loses two of its valence electrons to be isoelectronic with Ar and this confers a stable configuration to it. Non-metal oxygen atom accepts the electrons and adds 2 to its 6 electrons to become isoelectronic with neon. So, 1 metal cationic atom combines with 1 non-metal anionic atom to form the compound.WILL GIVE BRAINLIST IF RIGHT
