Answer:
Option B, HCO3 1-
Explanation:
The valence of Sodium ion is +1 and the valence of HCO3 is -1. Thus, sodium ion has an extra electron to be donated to complete its outer shell while HCO3 needs an electron to complete its outer shell
Hence Na will combine with HCO3 to form NaHCO3
Option B is correct
Answer:
120 liters
Explanation:
From the question,
Applying boyles law
PV = P'V'................ Equation 1
Where P = initial pressure, V = Initial Volume, P' = Final pressure, V' = Final Volume.
make V' The subject of the equation
V' = PV/P'............. Equation 2
Given: P = 2 kpa, V = 60 liters, P' = 1 kpa
Substitute these values into equation 2
V' = (2×60)/1
V' = 120 liters
Hence the right option is A. 120 liters
