Answer:
The reaction took place is-
Fe + CuSO4 → Fe(SO4) + Cu
the copper salt name is copper sulphate!
The statement describes the name of the copper salt is "copper sulphate."
What are salt?A salt is an ionic substance that is created when a positively charged ion bonds with a negatively charged ion.
The reaction occurred in the context of the image.
Fe + CuSO4(aq) → FeSO4(aq) + Cu(s)
A single displacement reaction is the sort of reaction. In this reaction, the highly reactive metal iron oxidises and creates ferrous sulphate by replacing the copper in copper sulphate by giving up two electrons.
Hence the correct answer is copper sulphate.

A covalent compound is a compound with a metal and a nonmetal ion sharing valence electrons (option A).
What is a covalent compound?A covalent compound is a molecule formed by covalent bonds, in which the atoms share one or more pairs of valence electrons.
Covalent bond is a type of chemical bond where two atoms are connected to each other by the sharing of two or more electrons.
Chemical compounds are generally grouped into one of two categories as follows;
covalent compounds ionic compoundsCovalent or molecular compounds generally result from two nonmetals reacting with each other. The elements form a compound by sharing electrons, resulting in an electrically neutral molecule.

c.Calcium ion (Ca2+)
d.Hydroxide ion (OH-)
Answers
Answer:
D - Hydroxide Ion (OH-)
Explanation:
A base provides either hydroxide ions (OH–) or other negatively charged ions that combine with hydrogen ions, reducing their concentration in the solution and thereby raising the pH. In cases where the base releases hydroxide ions, these ions bind to free hydrogen ions, generating new water molecules.

Answers
The term for the heaviness on something's surface that exerts a force over an area is pressure. The correct option is b. pressure
Definition of PressureFrom the question, we are to determine the term for the heaviness on something's surface that exerts a force over an area.
Here, we are talking about pressure.
Pressure is defined as the physical force exerted on an object. Mathematically, it is defined as the perpendicular force per unit area.
That is,
[tex]P = \frac{Force}{Area}[/tex]
Where P is the pressure
The units of pressure are Newtons per square meter (N/m²), Pascals etc.
Hence, the term for the heaviness on something's surface that exerts a force over an area is pressure. The correct option is b. pressure

All you need to know about CO2?
Answers
Answer:
Carbon is an element that's found all over the world and in every living thing. Oxygen is another element that's in the air we breathe. When carbon and oxygen bond together, they form a colorless, odorless gas called carbon dioxide, which is a heat-trapping greenhouse gas. Whenever we burn fossil fuels such as coal, oil, and natural gas—whether it's to drive our cars, use electricity, or make products—we are producing carbon dioxide.
The atmosphere isn't the only part of the Earth that has carbon. The oceans store large amounts of carbon, and so do plants, soil, and deposits of coal, oil, and natural gas deep underground. Carbon naturally moves from one part of the Earth to another through the carbon cycle. But right now, by burning fossil fuels, people are adding carbon to the atmosphere (in the form of carbon dioxide) faster than natural processes can remove it. That's why the amount of carbon dioxide in the atmosphere is increasing, which is causing global climate change.

What volume would a sample of gas occupy in LITERS at 0.985 atmospheres and a volume of 3.65 liters if the pressure were raised to 861.0 mmHg?
Answers
Answer:
3.18 L
Explanation:
Step 1: Given data
Initial pressure (P₁): 0.985 atmInitial volume (V₁): 3.65 LFinal pressure (P₂): 861.0 mmHgFinal volume (V₂): ?Step 2: Convert P₁ to mmHg
We will use the conversion factor 1 atm = 760 mmHg.
0.985 atm × 760 mmHg/1 atm = 749 mmHg
Step 3: Calculate the final volume of the gas
Assuming ideal behavior and constant temperature, we can calculate the final volume using Boyle's law.
P₁ × V₁ = P₂ × V₂
V₂ = P₁ × V₁/P₂
V₂ = 749 mmHg × 3.65 L/861.0 mmHg = 3.18 L

What is the empirical formula for a compound that has 1.5 moles of copper and 0.5 moles of phosphorus?
Answers
Answer:
[tex]Cu_{3}P[/tex]
Explanation:
usually, the first step is to calculate the moles but since that is already given in the question we can move onto the next step
least molar ratio:
Cu = [tex]\frac{1.5}{0.5}[/tex] = 3
P = [tex]\frac{0.5}{0.5}[/tex] = 1
thus, empirical formula = [tex]Cu_{3}P[/tex]
The empirical formula for a compound that has 1.5 moles of copper and 0.5 moles of phosphorus is Cu₃P.
What is the empirical formula?Empirical formula of any compound gives idea about the number of constituents particles present in that compound by mentioning the ration.
In the question, given that:
Moles of copper = 1.5 moles
Moles of phophorous = 0.5 moles
Now we divide the given moles by the smallest number to get the ration number as follow:
Cu : P
1.5/0.5 : 0.5/0.5
3 : 1
Hence, required empirical formula is Cu₃P.

Answers
Answer:
Volume of 6.5 moles of Helium at STP is 145.6954 L
Explanation:
As we know
[tex]pV = nRT[/tex]
At STP, temperature is 273.15 K and pressure is 1 atm
n is the number of moles which is equal to 6.5
R is the gas constant = 0.08206 L atm/K mol
Substituting the given values in above equation, we get -
[tex]1 * V = 6.5 * 0.08206 * 273.15\\V = 145.6954[/tex]Liters
Volume of 6.5 moles of Helium at STP is 145.6954 L
