Sonja and Jeremy performed several experiments to show how changes in temperature affected the volume of an inflated balloon. They made sure the pressure stayed the same. They also showed the effects of pressure on volume if temperature stayed the same. They organized their information in this table. Which experiments provide evidence for Boyle’s law?
Answer:
They also showed the effects of pressure on volume if temperature stayed the same
Explanation:
They also showed the effects of pressure on volume if temperature stayed the same is the experiment that will provide an evidence for Boyle's law.
Boyle's law states that "the volume of a fixed mass of a gas varies inversely as the pressure changes, if the temperature is constant".
The law is an affirmation of what happens when there is a dynamics between pressure and volume if temperature is made constant. So the experiment designed to investigate this proves and shows Boyle's law.Flame test lab
What are the answers to the last two columns and how do I solve them?
f = 5.08 x 10¹⁴/s
E=3.366 x 10⁻¹⁹ J
Further explanationRadiation energy is absorbed by photons
The energy in one photon can be formulated as
[tex]\large{\boxed{\bold{E\:=\:h\:.\:f}}}[/tex]
Where
h = Planck's constant (6,626.10⁻³⁴ Js)
f = Frequency of electromagnetic waves
f = c / λ
c = speed of light
= 3.10⁸
λ = wavelength
I will give example number 1, and for subsequent numbers, the steps will be the same
For NaNO₃ with λ=590 nm=5.9 x 10⁻⁷m
Frequency(f) :
[tex]\tt f=\dfrac{3.10^8}{5.9\times 10^{-7}}=5.08\times 10^{14}/s[/tex]

Which object absorbs the most sound waves?
O A. Tissue paper
O B. Air
O C. Earplugs
O D. Water
Answer:
Earplugs
Explanation:
Because sound waves absorb most sound, the sound is coming from the earplugs which creates the most sound waves rather than water, tissue paper, and air. Hope i helped :)

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.
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.

Which of the following is a balanced equation for the reaction described below?
Aqueous copper (II) chloride reacts with solid aluminum to produce aqueous aluminum chloride and solid copper.
A) CuCl2(aq) + Al(s) = AlCl3(aq) + Cu(s)
B) 3Cu2 Cl(aq) + Al(s) = AlCl3(aq) + 6Cu(s)
C) CuCl(aq) + Al(s) = AlCl(aq) + Cu(s)
D) 3CuCl2(aq) + 2Al(s) = 2AlCl3(aq) + 3Cu(s)
The balanced equation for the reaction is
3CuCl₂(aq) + 2Al(s) = 2AlCl₃(aq) + 3Cu(s). The correct option is - D) 3CuCl2(aq) + 2Al(s) = 2AlCl3(aq) + 3Cu(s)
From the question,
We are to determine which of the given equation for the described reaction is balanced.
The described reaction is the reaction between aqueous copper (II) chloride and solid aluminum to produce aqueous aluminum chloride and solid copper.
That is,
CuCl₂(aq) + Al(s) = AlCl₃(aq) + Cu(s)
Now, we will balance the above equation, using the smallest whole number coefficients
The balanced equation for the reaction is
3CuCl₂(aq) + 2Al(s) = 2AlCl₃(aq) + 3Cu(s)
Hence, the balanced equation for the reaction is
3CuCl₂(aq) + 2Al(s) = 2AlCl₃(aq) + 3Cu(s). The correct option is - D) 3CuCl2(aq) + 2Al(s) = 2AlCl3(aq) + 3Cu(s)

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.
