Answer:
The salt of benzoic acid would dissolve in the aqueous layer while cyclohexanol would remain in the CH2Cl2 layer.
Explanation:
The pH at which the amino acid exists primarily in its neutral form. hope this helps you :)
An element is a substance with only one type of particle
Answer: b. the volume of water vapour increases
Explanation:
when there's an increase in concentration, the equilibrium favours the forward reaction, more product is produced, froward reaction is faster
Answer:
9.3 × 10²³ molecules
Explanation:
Given data:
Mass of methane = 24.7 g
Number of molecules = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
For 24.7 g methane:
Number of moles = mass/ molar mass
Number of moles = 24.7 g/ 16.04 g/mol
Number of moles = 1.54 mol
1 mole = 6.022 × 10²³ molecules
1.54 × 6.022 × 10²³ molecules
9.3 × 10²³ molecules
The temperature of the container containing the 4.47 g of Ar is 358.16 K
<h3>How to determine the mole of Ar</h3>
- Mass of Ar = 4.47 g
- Molar mass of Ar = 40 g/mol
- Mole of Ar =?
Mole = mass / molar mass
Mole of Ar = 4.47 / 40
Mole of Ar = 0.11175 mole
<h3>How to determine the temperature </h3>
- Number of mole (n) = 0.11175 moles
- Volume = 2.65 L
- Pressure (P) = 1.24 atm
- Gas constant (R) = 0.0821 atm.L/Kmol
The temperature of the container can be obtained by using the ideal gas equation as illustrated below:
PV = nRT
Divide both side by nR
T = PV / nR
T = (1.24 × 2.65) / (0.11175 × 0.0821)
T = 358.16 K
