Sun (radiation), winds (eolic) and water (hydraulic) are all sources of energy that work together during rock formation.
What is rock formation?The rock formation is a very slow process that occurs at a geological time, which may take millions of years.
During this period, rocks are shaped by different types of energy, especially radiation and erosion (wind and water bodies)
In conclusion, the sun (radiation), winds (eolic) and water (hydraulic) work together during rock formation.

Joanne added iron filings to copper sulphate solution. she observed the reaction after one week. what is the name of the compound formed in this reaction?
The iron filings react with copper sulfate, the copper is displaced and iron sulfate results.
Copper sulfate + Iron reactionThe reaction between iron filings and copper sulfate is represented by the equation below:
[tex]Fe + CuSO_4--- > FeSO_4 + Cu[/tex]
The iron filings displace the copper from copper sulfate to form iron sulfate. Thus, elemental copper and iron sulfate are formed.
Iron is able to displace copper from copper sulfate because iron ranks higher than copper in the reactivity series.

Which is not a conjugate acid-base pair?
Question 1 options:
H3O+ and H2O
H2O and OH-
NH3 and NH2--
NH4+ and NH3
HNO2 and H2O
Answer:
Explanation:
''A conjugate acid is formed when a proton is added to a base, and a conjugate base is formed when a proton is removed from an acid.''
In a conjugate acid-base pair, only difference between molecules is the amount of ''H''
One molecule must have 1 more H
in the last example HNO2 and H2O, difference is not only the H amount also H2O doesn't have N. So we can't say they are conjugate acid-base pair.

Convert 65 grams of oxygen to moles
65 grams of oxygen is approximately equal to 2.03125 moles.
To convert 65 grams of oxygen to moles, we need to use the molar mass of oxygen (O₂), which is approximately 32.00 g/mol. Oxygen exists as a diatomic molecule (O₂), so we use the molar mass of O₂ to convert from grams to moles.
The formula for converting grams to moles is:
Moles = Mass (in grams) / Molar mass (in grams per mole)
Given:
Mass of oxygen = 65 grams
Molar mass of oxygen (O₂) = 32.00 g/mol
Moles of oxygen = 65 grams / 32.00 g/mol
Moles of oxygen ≈ 2.03125 moles
Therefore, 65 grams of oxygen is approximately equal to 2.03125 moles.

A 72.0-gram piece of metal at 96.0 °C is placed in 130.0 g of water in a calorimeter at 25.5 °C. The final temperature in the calorimeter is 31.0 °C. Determine the specific heat of the metal. Show your work by listing various steps, and explain how the law of conservation of energy applies to this situation.
Answer:
Approximately [tex]0.639\; {\rm J \cdot g^{-1} \cdot K^{-1}}[/tex].
Explanation:
Look up the specific heat of water:
[tex]c(\text{water}) = 4.18\; {\rm J \cdot g^{-1} \cdot K^{-1}}[/tex].
It is given that the mass of the water in this calorimeter is:
[tex]m(\text{water}) = 130.0\; {\rm g}[/tex],
The temperature of the water in this calorimeter has increased by:
[tex]\Delta T(\text{water}) = (31.0 - 25.5)\; {\rm K} = 5.5\; {\rm K}[/tex].
Thus, the energy that the water in this calorimeter absorbed would be:
[tex]\begin{aligned}& Q(\text{water})\\ =\; & c(\text{water}) \, m(\text{water}) \, \Delta T(\text{water}) \end{aligned}[/tex].
Let [tex]c(\text{metal})[/tex] denote the specific heat capacity of this piece of metal.
The mass of this piece of metal is:
[tex]m(\text{metal})[/tex].
The temperature of this piece of metal has been reduced by:
[tex]\Delta T(\text{metal}) = (96.0 - 25.5)\; {\rm K} = 70.5\; {\rm K}[/tex].
As this piece of metal cooled down, the energy it released would be:
[tex]\begin{aligned}& Q(\text{metal})\\ =\; & c(\text{metal}) \, m(\text{metal}) \, \Delta T(\text{metal})\end{aligned}[/tex].
Assuming that there is no exchange of energy between contents of this calorimeter and surroundings. By the law of conservation of energy, energy could neither be created nor destroyed.
Since energy could not be destroyed, the water in this calorimeter need to absorb the entirety of the energy that this piece of metal released. At the same, since no energy isn't created, the energy that the water absorbed would need to entirely come from this piece of metal. Therefore:
[tex]Q(\text{metal}) = Q(\text{water})[/tex].
[tex]\begin{aligned}& c(\text{water})\, m(\text{water})\, \Delta T(\text{water}) \\&= c(\text{metal})\, m(\text{metal})\, \Delta T(\text{metal}) \end{aligned}[/tex].
Rearrange and solve this equation for [tex]c(\text{metal})[/tex]:
[tex]\begin{aligned}& c(\text{metal}) \\=\; & \frac{c(\text{water}) \, m(\text{water})\, \Delta T(\text{water})}{m(\text{metal})\, \Delta T(\text{metal})} \\ =\; & \frac{4.18\; {\rm J \cdot g^{-1} \cdot K^{-1}} \times 130.0\; {\rm g} \times (31.0 - 25.5)\; {\rm K}}{72.0\; {\rm g} \times (96.0 - 25.5)\; {\rm K}} \\ \approx\; & 0.639\; {\rm J \cdot g^{-1}\cdot K^{-1}}\end{aligned}[/tex].

Which of the following ions is formed when the positive hydrogen ions from an acid bond to water molecules?
H−
OH−
H2O+
H3O+
Answer:
H20 +
Explanation:
The ion that is formed when the positive hydrogen ions from an acid bond to water molecules is H₂O⁺. The correct option is C.
What are hydrogen ions?
Hydrogen is an element that is present in the first place on the periodic table, and its atom's number is 1. The nucleus of hydrogen contains only one electron, and it contains a positive 1 charge.
Hydrogen is called hydrogen ion when it participates in any chemical reactions. They become charged and participate in electron bonding to form compounds.
The positive Hydrogen ions, when forming a bond to water molecules, will be represented as H₂O⁺ because hydrogen only contains a positive charge on it. The unit positive charge on the hydrogen is the proton present in its nucleus.
Thus, the correct option is C. H₂O⁺
