According to the all-or-none principle, the thing that would happen if a cell were depolarized twice the amount needed to produce an action potential would be : Nothing would happen because the cell must be polarized to fire.
all-or-none principle stated that the strength by which muscle fiber respond to a stimulus is independent to the strength of the stimulus.
Answer:when you eat the food its bonds break and it realeases energy when it breaks
Explanation:
According to the Aufbau principle, the 4s sublevel<span> is filled </span>before the 3d sublevel <span>because the </span>4s<span> is lower in energy. ... This is why when </span>electrons<span> are lost from the </span>orbitals<span> of the transition metals, they are lost from the </span>4s<span> first because it is higher in energy</span>
Answer:
at the temperature of the experiment is 0.56.
Explanation:
Moles of
= 0.35 mole
Moles of
= 0.40 mole
Volume of solution = 1.00 L
Initial concentration of
=
Initial concentration of
= ![\frac{0.40mol}{1.00L}=0.40M](https://tex.z-dn.net/?f=%5Cfrac%7B0.40mol%7D%7B1.00L%7D%3D0.40M)
Equilibrium concentration of
=
The given balanced equilibrium reaction is,
Initial conc. 0.35 M 0.40 M 0 M 0M
At eqm. conc. (0.35-x) M (0.40-x) M (x) M (x) M
Given: (0.35-x) = 0.19
x= 0.16 M
The expression for equilibrium constant for this reaction will be,
Now put all the given values in this expression, we get :
![K_{eq}=\frac{0.16\times 0.16}{(0.19)\times (0.24)}=0.56](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cfrac%7B0.16%5Ctimes%200.16%7D%7B%280.19%29%5Ctimes%20%280.24%29%7D%3D0.56)
Thus
at the temperature of the experiment is 0.56.
