Answer: mass of chlorine reacted is 3.18 g
Explanation:
2 K + Cl2 = 2KCl
no. of moles of K = mass / molar mass
= 3.50 / 39
= 0.0897
no. of moles of KCl = mass / molar mass
= 6.67 / 74.5
= 0.0895
no. of moles of Cl2 required = number of moles of KCl / 2
= 0.0895 / 2
= 0.0448 moles
mass of Cl2 required = no. of moles of Cl2 required x molar mass
= 0.0448 x 71
= 3.1808 g ≈ 3.18 g
Therefore mass of chlorine reacted is 3.18 g
Answer:
A
Explanation:
Location b is warmer meaning its closer to the equator and i got it write
P2 = 54.6 kPa
Explanation:
Given:
V1 = 10.0 L. V2 = 50.0 L
P1 = 273 kPa. P2 = ?
We can use Boyle's law to solve this problem.
P1V1 = P2V2
Solving for P2,
P2 = (V1/V2)P1
= (10.0 L/50.0 L)(273 kPa)
= 54.6 kPa
Explanation:
It is assumed that the particles of an ideal gas have no such attractive forces. The motion of each particle is completely independent of the motion of all other particles. The average kinetic energy of gas particles is dependent upon the temperature of the gas.
