By the process of natural selection, individuals in Finch 1 will evolve over time to resemble individuals in Finch 2.
What is natural selection?Natural selection is the process by which individuals who possess certain features or structures that make them better suited to their environment are able to survive and reproduce in their environment while those who do not have such features die off.
Since the preferred food for Finch 1 has become scarce due to drought, individuals in Finch 1 who have features that enable them eat larger seed will be naturally selected for survival , most population in Finch will be composed of such individuals.
Therefore, natural selection will cause individuals in Finch 1 to evolve over time to resemble individuals in Finch 2.

a particular radio station broadcasts radio waves at 100 MHz (100 million Hz). if radio waves travel at the speed of light (300 million m/s), then what is the wavelength of the radio waves that the station broadcasts.
Wavelength = (speed) / (frequency)
= (3 x 10⁸ m/s) / (1 x 10⁸ /s) = 3 meters
A sample of sodium hydroxide (naoh) has a mass of 160.0 g. the molar mass of naoh is 40.00 g/mol. how many moles of naoh does this sample contain? 4.000 moles 40.00 moles 160.0 moles 6,400 moles
The number of moles the sample of sodium hydroxide (NaOH) will contain is 4 moles.
How we calculate moles?Moles of any substance will be calculated by using the below formula:
n = W/M, where
W = given mass
M = molar mass
Given mass of NaOH = 160 g
Given molar mass of NaOH = 40 g/mole
On putting these values on the above equation, we get
n = 160 / 40 = 4 moles
Hence, required moles is 4 moles.

What is the main difference between Lewis structure and Bohr models?
The main difference between both models is that the Bohr model depicts all subatomic particles, but the Lewis dot diagram only depicts the symbol and valence electrons.
What is Lewis structure?Lewis Structure is a simplified representation of a molecule's valence shell electrons. It's used to depict how electrons in a molecule are distributed around specific atoms.
Electrons are shown as "dots" or as a line between two atoms when they are bonded in Lewis structure.The Bohr Model is a planetary model in which negatively charged electrons orbit a tiny, positively charged nucleus in the same way that planets orbit the sun.Hence the Bohr model depicts all subatomic particles, but the Lewis dot diagram only depicts the symbol and valence electrons.

How is temperature related to the physical change of a
substance?
Answer:
Physical conditions like temperature and pressure affect state of matter. ... When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation)
Answer:
Temperature is a measure of the kinetic energy of particles in a substance. As temperature increases, the atoms or molecules in a substance gain energy. As temperature decreases, the particles lose energy. A change in the energy of particles causes a change in their arrangement. A change in the arrangement of particles can lead to a physical change.

How much heat is produced by the combustion of 125 g of acetylene (C2H2)?
C2H2(g) +
202(8)
2C02(8) + H2O(1)
AH = -1301.1 kJ/mol
The amount of heat produced when 125 g of acetylene C₂H₂ combust in air is –6255.3 KJ
Balanced equationC₂H₂ + 5/2O₂ —> 2CO₂ + H₂O ΔH = –1301.1 KJ/mol
From the balanced equation above,
1 mole of C₂H₂ releases –1301.1 KJ of heat energy
But
1 mole of C₂H₂ = (2×12) + (1×2) = 26 g
Thus,
26 g of C₂H₂ releases –1301.1 KJ of heat energy
How to determine the heat released by 125 g of C₂H₂From the balanced equation above,
26 g of C₂H₂ releases –1301.1 KJ of heat energy
Therefore,
125 g of C₂H₂ will release = (125 × –1301.1) / 26 = –6255.3 KJ of heat energy
Thus, –6255.3 KJ of heat energy were produced from the reaction.

Solid zinc and aqueous lead (II) nitrate react to from aqueous zinc (II) nitrate and solid lead.
Zn(s) + Pb(NO₃)₂ (aq) → Zn(NO₃)₃ (aq) + Pb (s)
Further explanationThere are two types of chemical reactions that may occur.
single-replacement reactions and double-replacement reactions.
A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds
A + BC ⇒ AC + B
Not all of these reactions can occur. We can use the activity series, which is a list of elements that can replace other elements below / to the right of them in a single replacement reaction.
This series is better known as the Volta series, where the metal element with a more negative electrode potential is on the left, while the element with a more positive electrode potential on the right.
The more left the position of a metal in the series, the more reactive metal (easy to release electrons)
Generally, the Volta series used is
Li K Ba Sr Ca Na Mg Al Mn Zn Cr Fe Cd Co Ni Sn Pb H Sb Bi Cu Hg Ag Pt Au
Solid zinc and aqueous lead (II) nitrate react to from aqueous zinc (II) nitrate and solid lead.
Can be expressed in chemical equations :
Zinc + aqueous lead (II) nitrate ⇒aqueous zinc nitrate + lead metal
Zn(s) + Pb(NO₃)₂ (aq) → Zn(NO₃)₃ (aq) + Pb (s)
Reactants : Zn and Pb(NO₃)₂
Products : Zn(NO₃)₃ and Pb
The existing Zinc element can replace the Lead element, which is on the right side of Zn, so the reaction will occur.
The chemical equation below shows the reaction between carbon dioxide (CO2) and lithium hydroxide (LiOH). CO2 2LiOH Right arrow. Li2CO3 H2O The molar mass CO2 is 44. 01 g/mol. How many moles of LiOH are needed to react completely with 25. 5 g of CO2? 0. 290 moles 0. 579 moles 1. 16 moles 1. 73 moles.
Answer:
C
Explanation:
The reaction between carbon dioxide and lithium hydroxide can be represented by the equation:
[tex]\displaystyle \text{CO$_2$} + 2\text{LiOH} \longrightarrow \text{Li$_2$CO$_3$}+ \text{H$_2$O}[/tex]
We want to determine the amount of moles of LiOH needed to react completely with 25.5 g of CO₂.
Determine the number of moles of CO₂ in 25.5 g of CO₂:
[tex]\displaystyle 25.5\text{ g CO$_2$} \cdot \frac{1\text{ mol CO$_2$}}{44.01\text{ g CO$_2$}} = 0.579\text{ mol CO$_2$}[/tex]
Use stoichiometry to determine the amount of LiOH necessary. CO₂ and LiOH are in a 1:2 ratio. That is, for every one mole of CO₂ that reacts, two moles of LiOH must also react.
[tex]\displaystyle 0.579\text{ mol CO$_2$} \cdot \frac{2\text{ mol LiOH}}{1\text{ mol CO$_2$}} = 1.16\text{ mol LiOH}[/tex]
In conclusion, our answer is C.
