Why do we sometimes use roman numerals in naming ionic compounds?
Answers
We use roman numerals to indicate the oxidation state of metal atoms when naming compounds especially in the case of coordination compounds. It is a standard system of nomenclature.
What is oxidation state?Oxidation state of a species is the number electrons gained or lost. Oxidation state increases if electrons are lost from the atom and it will be decreased if electrons are gained.
For example, copper is in + 2 oxidation state in CuSO₄, thus it can be indicated as Cu(II). Copper can exists is +3 oxidation too. Thus the representation will be Cu (III).
All the transition metals like copper exhibit various oxidation state. So it is important to indicate in which oxidation state they are in a particular compound. In the compound Fe₂O₃, iron is in + oxidation state whereas in FeSO₄, it can be +2 . Thus it is important to note whether it is Fe (II) or Fe (III).

Why is methanol more soluble in water than butanol
Answers
Answer:
Explanation: The longer the alkyl chain, the less soluble in water is the alcohol. Methanol and ethanol are infinitely miscible in water; propanol and butanol have limited solubility. ... Hydrogen bonding with water thus becomes less viable, and solubility of the long-chain alcohol IN WATER decreases.

Answers
Answer:
C
I think not positive good luck tho
A heavily forested area is one that has a dense and large number of trees. The areas like mountainous tracks or the protected frosts areas of wildlife.
In order to have solar collectors that meet the demands of energy generation. Some parts of the forests may have to clear off. As for collecting the sunlight, there needs to be clear ground. As trees and forests absorb insolation.Hence the option D is correct, trees need to to be cleared for working efficiently.

the electrolyte in automobile lead storage batteries is a 3.75 sulfuric acid solution that has density of 1.230g/mL. calculate the mole fraction.
Answers
The mole fraction of sulfuric acid : 0.073
Further explanationGiven
3.75 M sulfuric acid solution that has density of 1.230 g/mL
Required
The mole fraction
Solution
3.75 M = 3.75 mol/L
For 1 L solution :
mass of solution = 1230 g
mass Sulfuric acid : 3.75 mol x 98 g/mol=367.5 g
mass water = 1230-367.5 = 862.5 g
mol water = 862.5 : 18 g/mol= 47.92
mol total = 3.75 + 47.92 = 51.67
mole fraction of sulfuric acid :
= 3.75 : 51.67
= 0.073

a. 745 K
b. 62.5 K
c. 298 K

The maximum temperature : a. 745 K
Further explanationGiven
Gas at 25°C(298 K) and at a pressure of 0.800 atm
Final pressure = 2 atm
Required
Final temperature
Solution
Gay Lussac's Law
When the volume is not changed, the gas pressure in the vessel is proportional to its absolute temperature
[tex]\tt \dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}[/tex]
Input the value :
T₂=(P₂T₁)/P₁
T₂=(2 atm x 298 K)/0.8 atm
T₂ = 745 K = 472 °C

When a fluorine atom becomes an ion, it will
A) gain an electron and increase in size
B) lose an electron and increase in size
C) gain an electron and decrease in size
D) lose an electron and decrease in size
Answers
Answer:
A) gain an electron and increase in size
Explanation:
Fluorine is a Group 17 element, making it a halogen. This means that it has 7 valence electrons in its outer shell. It only needs one more electron to fill its outer shell and gain stability. When fluorine becomes an ion, it gains an electron and becomes F⁻. Adding electrons creates a larger ion because the electrons occupy a larger volume due to mutual repulsions pushing them apart.
Hope that helps.
When a fluorine atom becomes an anion, it will gain an electron and increase in size. Therefore, option (A) is correct.
What is an ion?An ion is a chemical specie that holds a positive or negative charge. The term ‘ion’ refers to atoms or molecules with non-zero net charges associated with them. Therefore, all ions have either a greater number of electrons than protons in their atomic structures or a greater number of protons than electrons.
If the number of protons is greater than electrons are termed to hold a net positive charge and are commonly referred to as cations. The ions that contain a greater number of electrons than protons hold a net negative charge and are known as anions.
The electronic configuration of the fluorine is 1s²2s²2p⁵. As the fluorine atom accepts one electron in its valence shell it becomes anion F⁻. The number of protons is less than electrons therefore effective nuclear charge decreases and the size of the ion increases.

How is the chemical bonding within a crystal of gold (Au) different from the
chemical bonding within a crystal of table salt (NaCl)?
Answers
Answer:
In the gold crystal, the atoms are bonded by freely moving electrons. In the salt crystal, the atoms are bonded by the attraction of opposite electrical charges.
Explanation:
A.pex
A crystal of Gold (Au) has metallic bonding whereas a crystal of NaCl has ionic bonding.
What is Chemical Bonding?Chemical bonding refers to the formation of a chemical bond between two or more atoms, molecules or ions to give rise to a chemical compound.
Ionic bonding occurs by transfer of electrons from one atom to another and is usually between a metal and a non metal atom. This type of bond is classically described as occurring when atoms interact with one another to either lose or gain electrons.
Metallic bonds are the chemical bonds that hold atoms together in metals.
Therefore, A crystal of Gold (Au) has metallic bonding whereas a crystal of NaCl has ionic bonding.
