Answer:
140.32mL per hour
Step-by-step explanation:
Rate of leakage of nitrogen ballon = 75 mL/h
Rate of leakage of helium ballon = x
Molar mass of nitrogen= Mn = 14
Molar mass of helium = Mh = 4
Effusion formula
Rate of effusion of helium/ Rate of effusion of nitrogen= √(Molar mass of nitrogen/Molar mass of helium)
Rate of effusion of helium = 75mL/h * √(14/4)
= 140.32mL/h
Let U = {1, 2, 3, 4, 5, 6, 7}, A= {1, 3, 4, 6}, and B= {3, 5, 6}. Find the set A’ U B’

Answer:
Step-by-step explanation:
A'={2,5,7}
B'={1,2,4,7}
A'UB'={1,2,4,5,7}
Answer:
t = 6
Step-by-step explanation:
Because you need to transfer the 64 to the other side dividing and the operation will be t = 384 / 64
Part 1: I'm pretty sure B is soluble in water.
Part 2: The data is showing that A isn't soluble at all (probably cause it's solid or a lipid or something) because the amount undissolved stays the same as B changes in solubility.
Hi there!
To find your answer, let us see what number can go evenly into 17 and 147.
Since it looks like nothing can go into each number evenly, is already simplified down to its lowest terms and it can't go any lower than that.
Hope this helps! :D
