I and II are the functional isomers of each other. Hence option A is correct.
What is isomer?Isomer is defined as when multiple compounds with the same chemical formula but different chemical structures exist. A prefix that denotes the number of carbons is followed by the suffix -ane, which designates that the molecule is an alkane. By counting the chiral centers in a chemical, one can determine how many optical isomers exist. The formula 2n1, where n is the number of chiral centers, indicates the greatest number of optical isomers.
They are functional isomers because alcohol CH3CH2CH2OH and ether CH3CH2OCH3 contain different functional groups. Functional isomerism, which refers to isomers that differ in the functional group present in the carbon chain, is exemplified by H3-CH2OH and CH3-O-CH3.
Thus, I and II are the functional isomers of each other. Hence option A is correct.

Which non-destructive technique is used for analyzing carpet fibers at a crime scene?
______________ is a non-destructive technique used for analyzing carpet fibers at a crime scene and preserving evidence in the original form.
( forensic science question)
Room temperature fluorescence spectroscopy is a non-destructive technique used for analyzing carpet fibers at a crime scene and preserving evidence in the original form.
In investigations, it is often necessary to preserve the physical integrity of evidence so that it can be presented in court. It therefore becomes important to use methods of analysis that are non - destructive when analyzing the material.
One of the most useful non - destructive methods of analysis is room temperature fluorescence spectroscopy. This method of analysis is accurate, yet preserves the physical integrity of evidence.

why is water able to easily dissolve ionic compounds
Answer:
Water is a covalently bonded molecule. H2O-> Oxygen and hydrogen are both nonmetals. Ionic compounds are made up of a nometal and metal which causes it to have electrical components. A covalent bond is stronger than an ionic bond, which allows water to break down ionic salts.

A quantity of gas has a volume of 2250 at a temperature of 45 C and a pressure of 650 torrWhat is the temperature (in °C) if the volume remains unchanged but the pressure is decreased to 565 torr?
Answer:
your answer is 769
Explanation:
i took the test lol
The pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature, according to Gay Lussac's Law. When you heat a gas, the molecules gain energy and move faster. This means more impacts on the container's walls and an increase in pressure.
The temperature at 565 torr = 276.5 K
What are gas laws?Gas laws are laws that relate a gas's pressure, volume, and temperature. Boyle's law, named after Robert Boyle, states that the pressure P of a gas varies inversely with its volume V at constant temperature, or PV = k, where k is a constant.Boyle's Law states that when the temperature and mass are both constant, the volume of a given amount of gas held at constant temperature varies inversely with the applied pressure.Charles' law states that if the pressure remains constant, the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature.The pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature, according to Gay Lussac's Law. When you heat a gas, the molecules gain energy and move faster. This means more impacts on the container's walls and an increase in pressure.Avogadro's law states that equal volumes of different gases contain an equal number of molecules under the same temperature and pressure conditions.

Which describes a molecule? (Select all that apply.)
It can be two or more of the same elements combined together.
It can be one element by itself.
It can be two or more different elements combined.
It can be the combination of different neutrons.
Answer:
a) It can be two or more of the same elements combined together.
A molecule is two or more atoms of the same element chemically combined.
Example is an oxygen molecule.
Molecules can be described as two or more of the same or different elements combined together. Therefore, options (A) and (C) are correct.
What is a molecule?A molecule can be described as a combination of two or more atoms that form the smallest unit into which the structure and chemical properties of that substance can be classified and preserved by a pure substance.
A molecule may be homonuclear if it consists of atoms of a single chemical element such as oxygen molecule (O₂) or it may be heteronuclear such as water (H₂O).
A molecule consists of an arrangement of atoms held together by the forces of valence. Two atoms that are chemically combined comprise diatomic molecules.
Heteronuclear diatomic molecules consist of two combined atoms of the same substance such as Carbon monoxide (CO), hydrochloric acid (HCl), etc.
Therefore, a molecule can consist of atoms of the same or different elements.

Why do solids maintain their volume and shape? cause-effect
A.) Because they vibrate
B.)because they are packet tight
C.) because they are crystalline
B.)because they are packet tight
Answer:
Because they are packet tight.
Explanation:
Solids maintain their volume and shape because they are packet tight.
A solid's particles fit closely together. The forces between the particles are so strong that the particles can not move freely; they can only vibrate. This causes a solid to be a stable, non-compressible shape with definite volume.Name an element that can be used to date back billions of years?

if equations are not balanced,what must you do?
If a chemical equation is not balanced it implies that either mass has been created or destroyed which is a contradiction to law of conversation of mass which states that matter can niether be created nor destroyed.
In order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. In order make both sides equal, you will need to multiply the number of atoms in each element until both sides are equal.

-If sulfuric acid (H2SO4) reacts with 29 grams of sodium chloride (NaCl), how many grams of hydrochloric acid (HCl) are produced? H2SO4 + NaCl > HCl + Na2SO4
- In the same reaction, how much salt (NaCl) is needed to produce 4.0 moles of sodium sulfate (Na2SO4)?
- In the same reaction, if you started with 100 moles of sulfuric acid (H2SO4), how many moles of hydrochloric acid (HCl) could you produce?
Explanation:
mole = mass/molar mass
mole of Nacl = mass/mm
molar mass of Nacl = Na + Cl = 23+35=58
mole of NaCl = 29/58
mole of NaCl = 0.5mol
H2SO4 + NaCl ====> HCl + Na2SO4
1. 1. 1. 1
since mole of NaCl is 0.2mol then mole of HCl is also 0.2mol since they are all in the same ratio
mole of HCl = Mole of NaCl = 0.5mol
mass of HCl = ?
molar mass of HCl = H + Cl = 1+ 35=36
mole of HCl = mass /molar mass
0.5= mass/36
mass = 0.5×36 = 18 grams
