Answer:
Opening of Na channels in the membrane
Explanation:
Depolarization is the mechanism of opening or closing channels in the membrane. The depolarization of action potential requires opening of Na channels in the membrane to increase the membrane potential through the increased influx of Na ion
H2SO4 ---> 2H^+ + SO4^2-
Hence n H+ = 9 mols
Mass of H = nM = (9*1) = 9g
Alternately
mass of H2SO4= nM= 4.5*98= 441
Mass of H= mass h2so4 * molar mass of H/molar mass of h2so4
Mass of H= 441 * 2/98 = 9g
Answer:
A) 60
Explanation:
Given data:
Distance traveled by car = 210 km
Time taken = 3.5 hour
Speed of car = ?
Solution:
Formula:
S = d/t
s = speed of car
d = distance
t = time
by putting values,
s = 210 km / 3.5 hour
s = 60 km/hour
