The segment of the myocardial conduction framework that has the quickest rate of unconstrained depolarization is the S-A node.Depolarization goes through particular conduction pathways from the S-A hub to the A-V hub. This atrial depolarization happens at a most extreme rate of 0.3 m/sec
Answer:
14 amu
Explanation:
The atomic mass is equal to the sum of protons and neutrons. There are 6 protons and 8 neutrons. 6+8=14amu
Answer: -705.2 kJ
Explanation:
According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.
According to this law, the chemical equation can be treated as ordinary algebraic expression and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.
(1)
(2)
The final reaction is:
(3)
Reversing (2)
(2')
By adding (1) and (2')
Hence .
Answer:
Yes
Explanation:
Scientists using the latest microscopic technology have found they can move individual atoms around a surface at will, a breakthrough that could have profound implications in the ultra-small world of electronics and even in industry
