Answer:
freezing
Explanation:
because boiling is when subatomic are really far apart and excited, and freezing is when they are close together and compact, slow, and stable.
1.64 atm
PV = nRT —> P = nRT / V
n = 3 moles
R = 0.08206 L atm / mol K
T = 400 K
V = 60 L
P = (3)(0.08206)(400) / 60 = 1.64 atm
Answer:
sodium has a lower electronegativity:)
Explanation:
To accurately measure the final volume of a solution in a burette, it is important that you read of the measurement in the lower meniscus like for water and for substances like mercury you read it on the upper meniscus. This is the standard way of reading volumes in laboratory apparatus. Also, it should be that the apparatus standing vertically in a plain surface.
