What is molar entropy?The entropy content of one mole of a pure substance at any temperature of interest and a standard state of pressure is known as the standard molar entropy in chemistry. The standard temperature and pressure are frequently selected to be these. One mole of a sample under standard state conditions is said to have a standard molar entropy, or degree of unpredictability. J/molK, or joules per mole Kelvin, are the typical units of standard molar entropy. Entropy is a unitary measure of the amount of thermal energy in a system that cannot be used to carry out beneficial work.

What is the hydronium ion concentration of an acid rain sample that has a pH of 3.45?
A) 2.82 × 10-11 M
B) 3.55 × 10-4 M
C) 3.45 M
D) 10.55 M
The hydronium ion concentration of an acid rain sample that has a pH of 3.45 is 3.55 × 10-4 M.
Given the pH of hydronium ion = 3.45
The hydronium ion concentration can be calculated from the pH using the exact opposite mathematical procedure. The conjugate acid of H2O is H3O+. In aqueous solutions, a proton is denoted by the symbol H3O+. The proton would create a different structure in a non-aqueous solution. H2O(l) → H+(aq) + OH-(aq).
Because hydrogen ions bond to water molecules to generate hydronium ions, the equations pH = -log[H3O+] and pH = p[H3O+] can be used to compute a solution's pH.
pH + pOH = 14 then [H+] = 10^-pH
So the concentration of hydronium ion = 10^-3.45 = 3.55 × 10-4 M

1) Propanyl chloride is an acid chloride. This propanyl chloride on reaction with LiAlH4 and H3O+ yield corresponding alcohol. 2. Methyl propanoate on reaction with aniline yield corresponding amide. 3. Amide on hydrolysis yield carboxylic acid.
When methyl propanoate reacts with lithium aluminum hydride (LiAlH4), the carbonyl group of the ester is reduced by the hydride ion (H-) from LiAlH4 to form an alcohol. The final product of this reaction would be the alcohol derived from the acyl portion of methyl propanoate. When this alcohol is then treated with hydrochloric acid (HCl) or another acid, it will undergo a protonation, forming the corresponding alkyl carbinol. The final product of this reaction is the carbinol and the carboxylic acid derived from the acyl portion of methyl propanoate.The product of the reaction between methyl propanoate and LiAlH4 then H3O+ would be the following structure:

decomposed?
287.13
200g
888g
1148.52g
287.13 grams of Al₂O₃ were decomposed. Therefore, option A is correct.
What is molar mass ?The term molar mass is defined as the mass in grams of one mole of the compound. A mole of any substance is 6.022 × 10²³ molecules. It is called as Avogadro's number. The molar mass is a bulk property, it is not molecular, property of a substance.

D) H2C=CH-CH2+ for the last C: sp hybridization.
What is hybridization ?
Hybridization is the process by which atomic orbitals combine to form new hybrid orbitals with different energy levels and geometric shapes. These hybrid orbitals are used to form chemical bonds between atoms. The type of hybridization depends on the number of atoms and lone pairs of electrons surrounding the central atom in a molecule. Some common types of hybridization include sp3 (four orbitals), sp2 (three orbitals), and sp (two orbitals) hybridization.
A) CH3CO2- for the last C: The last C atom in CH3CO2- is bonded to one O atom and two C atoms. In order to form these bonds, the C atom needs to have three orbitals available for bonding, which means it is in sp2 hybridization.
B) PH4+ for P: The P atom in PH4+ is bonded to four H atoms. In order to form these bonds, the P atom needs to have five orbitals available for bonding, which means it is in sp3 hybridization.
C) AlF3 for Al: The Al atom in AlF3 is bonded to three F atoms. In order to form these bonds, the Al atom needs to have six orbitals available for bonding, which means it is in sp3d2 hybridization.
D) H2C=CH-CH2+ for the last C: The last C atom in H2C=CH-CH2+ is bonded to one H atom and one C atom. In order to form these bonds, the C atom needs to have two orbitals available for bonding, which means it is in sp hybridization.

What is specific heat?In thermodynamics, the specific heat of a substance (symbol cp) is the heat capacity of a sample of the substance divided by the mass of the sample, sometimes called the mass heat capacity. Informally, it is the amount of heat that must be added to a unit mass of a substance to cause a unit temperature rise. The SI unit for specific heat capacity is Joule/Kelvin/Kilogram, J kg⁻¹ K⁻¹. For example, it takes 4184 Joules of heat to raise the temperature of 1 kg of water by 1 K, so the specific heat capacity of water is 4184 J kg⁻¹ K⁻¹.
Q = mcΔT
1 Kcal. = 4184 J
0.9 K Cal. = 4184 × 0.9
0.9 K Cal. = 3765.6 J
3765.6 = 75 × 4.186 × ΔT

Properties of matter affect how people need to handle the different states of matter, such as the propane gas that is being carried inside this tanker truck. Look at the tank of the truck that contains the gas. Why is this tank design useful for transporting gas? Considering the volume and shape properties of each state of matter, how might the container on a truck carrying a liquid or a solid be designed differently?
Answer:
Explanation:
The tank design of the truck is useful for transporting gas because it is able to hold large volumes of gas while taking up minimal space. The container is typically long and cylindrical in shape, allowing the gas to be compressed and stored in a smaller space.
If the truck were carrying a liquid, the container would likely be designed differently. Liquids take the shape of their container, so the container would need to be able to hold the liquid in an upright position without spilling. This could be achieved through the use of a tank with a closed top and a small opening at the bottom for dispensing the liquid.
For a solid, the container would also need to be designed differently. Solids have a fixed shape and volume, so the container would need to be able to hold the solid without crushing or altering its shape. This could be achieved through the use of a container with walls that are thick and sturdy enough to support the weight of the solid.
