The number of atoms in 16.25 g of Al is calculated here. One mole or 26.98 g of Al contains 6.022 × 10²³ atoms. Thus, the atoms in 16.25 g or 0.60 mol of Al contains 3.62 × 10²³ atoms.
What is one mole ?Any substance containing 6.022 × 10²³ atoms is called one mole of that substance. This number is called Avogadro number. Therefore, one mole of every substances contains Avogadro number of atoms. The mass of one mole of an atom is called its atomic mass.
Al is 13th element in periodic table. Its atomic mass is 26.98 g/mol. Thus, the number of moles of 16.25 g of Al is calculated as follows:
no.of moles = given mass/atomic mass
= 16.25/26.98 =0.60 moles.
1 mole of Al contains 6.022 × 10²³ atoms. Thus, 0.60 moles contains 6.022 × 10²³ × 0.60 = 3.62 × 10²³ atoms.
Therefore, to calculate the number of atoms in a given number of moles of an element multiply the number of moles with Avogadro's number.

A gas is enclosed in a cylinder fitted with a light frictionless piston and maintained at atmospheric pressure. When 254 kcal of heat is added to the gas, the volume is observed to increase slowly from 12. 0 m3 to 16. 2 m3.
This unit is explained as the work of a driving force of a newton whose point of application moves one meter in the direction of the force
1. The work done by the gas is 425,565 Joules
2. The change in internal energy of the gas is 637,171 Joules
1. W = P (V2 - V1) difference of v1 and v2.
P = 1 atm = 101325 N/m^2
V2 = 16.2 m^3
V1 = 12 m^3
W = 101325(16.2 - 12) = 101325 × 4.2 = equal to 425,565 Joules
2. ∆U = Q - W
Q = 254 kcal = 254×4184 = 1,062,736 Joules
now, Q is equal to 1,062,736 joules
∆U = 1,062,736 - 425,565 = 637,171 Joules

how many moles of an alcohol are needed to react with 1 mole of an aldehyde to form a hemiacetal?
1 mole of an alcohol are needed to react with 1 mole of an aldehyde to form a hemiacetal.
Alcohol and ether are joined to the same carbon atom as hemiacetals. Hydrogen is positioned at the fourth bonding position. To create a hemiacetal, 1 mole of an alcohol must react with 1 mole of an aldehyde. When an aldehyde and an alcohol interact, a hemiacetal is created. This can happen in one of two ways: as a neutral reaction or catalyzed by an acid. Only the alcohol and the aldehyde are involved in the neutral reaction. The carbon is attacked by the alcohol. The oxygen is forced to receive those extra electrons. Therefore, the ether has a positive charge while the oxygen has a negative charge. In order to create the hemiacetal, the additional proton (hydrogen) on the ether can then be transferred to the oxygen.

ΔG = ΔH - TΔS
ΔG = -25.134x + 165
ΔH = 165
TΔS = 25.134x
ΔS = (ΔH - ΔG)/T

So, in this case, the electrostatic force between the nucleus and the shell-bound electrons is used to determine the ionic radius.

What is the volume of 0.58 moles
of H2 gas at STP?
Answer:
volume = 0.013 m³
Explanation:
The question asks us to calculate the volume of 0.58 moles of H₂ gas at STP.
To do this, we must use the ideal gas equation:
[tex]\boxed{pV = nRT}[/tex],
where:
• p = pressure in Pa
• V = volume in m³
• n = number of moles
• R = molar gas constant (8.31 Jkg⁻¹K⁻¹)
• T = temperature in K
From the question, we know that the number of moles of H₂ is 0.58. Therefore, n = 0.58. We also know that the volume is asked for when the gas is at STP, therefore: T = 273 K, and p = 101.3 × 10³ Pa.
Using this data and the formula above, we can calculate the volume of the gas:
pV = nRT
⇒ 101.3 × 10³ × V = 0.58 × 8.31 × 273
⇒ V = [tex]\frac{0.58 \times 8.31 \times 273}{101.3 \times 10^3}[/tex]
⇒ V = 0.013 m³
Therefore, the volume of the gas is 0.013 m³.

Ca(OH)₂ = 40 + 2( 15.99 + 1 )
= 74.10 g/mol
The moles of the K₂SO₄ in the 15 g of the K₂SO₄ :
Moles = mass / molar mass
Moles = 15 / 174.25
Moles = 0.086 mol
The moles of the glucose, C₆H₁₂O₆ = 3.55 mol
The mass of the glucose = moles × molar mass
= 3.55 × 180
= 639 g

Given the equation; Cl2 + Ca(OH)2 = CaCl + H2O, calculate the balanced half equation and the balanced net equation
PLEASE I NEED IT NOW!!!
The balanced reaction equation is; [tex]2Ca(OH)_{2} + 2Cl_{2} ----- > Ca(ClO)_{2} + CaCl_{2} + 2H_{2} O[/tex]
What is the balanced reaction equation?We have to note that when we are talking about the reaction equation, what we mean is how the reactants and the products are able to exists in the system.
For the reaction, the species that we find at the right hand side are called the reactants that are in the system while the species that we find on the left hand side are called the products of the reaction. Thus, the balanced reaction equation is shown above.
