<span>Magnesium is a strong anode than calcium. So, Mg will be oxidized into Mg2+. So instead of having Ca being the reducing agent, Mg will takes its place. That's how the "Blocking" occur.
</span><span>Without Ca2+, no neurotransmitter was released because the exocytosis of the synaptic vesicles is dependent upon Ca2+.
</span>So, when magnesium is added to the extracellular fluid it blocks the calcium channels and inhibits the release of <span>neurotransmitter.</span>
Answer:
Explanation:
The mass of radioactive isotope at a certain time is given by the following expression:
Time constant can be calculed in terms of half-life:
The initial mass is:
The molar mass of CO is 28 g/mol while that of CO2 is 44
g/mol. Let us calculate the total moles present in the container.
total moles = [5g / (28 g/mol)] + [5g / (44 g/mol)]
total moles = 0.2922 mol
Using PV = nRT, we get the pressure:
P = nRT / V
P = (0.2922 mol * 0.0821 L atm/mol K * 323.15 K) / 0.75 L
<span>P = 10.34 atm</span>
