Answer:
Thermometer A, because it measures accurately to the tenths digit.
Answer : The partial pressure of the 
in the tank in psia is, 32.6 psia.
Explanation :
As we are given 75 % and 25 % 
in terms of volume.
First we have to calculate the moles of and .
Now we have to calculate the mole fraction of .
Now we have to calculate the partial pressure of the gas.
conversion used : (1 Kpa = 0.145 psia)
Therefore, the partial pressure of the in the tank in psia is, 32.6 psia.
Answer:
false
Explanation:
As we know that in sodium-potassium pump .
sodium potassium move 3Na+ outside the cells
and moving 2k+ inside the cells
so that we can say that given statement is false
Answer FALSE
