Explanation:
As per the measurements that are made by the student are as follows.
21.6 cm is equivalent to 8.5 inch
Therefore, 1 cm for the given situation will be equivalent to inch as follows.
1 cm = inch
= 0.393 inch
Hence, we will calculate the ratio of cm : inch as follows.
Ratio of cm : inch =
= 0.39
Thus, we can conclude that the ratio of cm/inch using the students data is 0.39.
The correct answer is option A.
All the particles carry the same charge, which could be either positive or negative.
All the particles of substance X will have same charge on its surface, which is balanced by the oppositely charged ions in the water.
For example, soap solution (sodium palmitate) dissociates into ions:
C₁₅H₁₁COONa --> C₁₅H₁₁COO⁻ + Na⁺
The cations (Na⁺) passes into the water while the anions (C₁₅H₁₁COO⁻) form aggregates or colloids.
Answer is 128.892 g.
moles (mol) = mass (g) / molar mass (g/mol)
According to the given data,
moles = 4.60 mol
mass = ?
molar mass = 28.02 g/mol
By substitution,
4.60 mol = mass / (28.02 g/mol)
mass = 4.60 mol x 28.02 g/mol
mass = 128.892 g
Hence, mass of 4.60 mol of N₂ is 128.892 g.
It is equal to a gram, as there are 1,000,000 milligrams in a gram.
Answer:
The value of Kp for the system = 0.0128 atm
Explanation:
Let, the gaseous substance is SO₂Cl₂
SO₂Cl₂ ⇄ SO₂ + Cl₂
Initially x 0 0
At equilibrium (x - 14.5%x) 14.5%x 14.5%x
= 85.5 % x
Total moles of gases at equilibrium
= 85.5 % x + 14.5%x + 14.5%x
= 114.5 % x
Partial pressure of SO₂ () =
Partial pressure of Cl₂
Partial pressure of SO₂Cl₂
So,
