Answer:
Explanation:
Hello,
Considering the given information, the new concentration of Na+inside will be (13.6 + 4) mM = 17.6 mM, and outside will be (150 + 0.04) mM = 150.04 mM due to the previous specified conditions.
Now, the recalculation of the Nerst potential at the supposed temperature of 25 °C (which is modifiable) is done via:
Best regards.

Answer:
1000 g
Explanation:
Given data:
Initial temperature of water = 45°C
Final temperature of water = 25°C
Heat released = 20 cal (4184×20 = 83680 j)
Mass of water = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Specific heat capacity of water is 4.184 j/g.°C
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 25°C - 45°C
ΔT = -20°C
83680 j = m × 4.184 j/g.°C ×20°C
83680 j = m × 83.68 j/g
m = 83680 j / 83.68 j/g
m = 1000 g
The neutron and proton are both located in the nucleus of the atom whereas the electron is orbiting the nucleus. The average mass of the proton is 1.6726219 × 10-27 kilograms and the neutron is practically the same. The electron’s mass is 9.10938356 × 10-31 kilograms. The charge of the proton is +1e or 1.602x10-19 C and the neutron is neutral. The charge of an electron is 1.60217662 × 10-19 coulombs
