The answer is sodium chloride.
Explanation:
Sodium chloride refers to table salt, and is the most abundant of salts found in seawater.
For an non spontaneous reaction between silver (Ag) and copper (Cu) and their ions, Cu is the oxidizing agent while Ag+ is the reducing agent,
The following reactions will take place;
Anode Cu = Cu+2 + 2e- E= +0.34 volts
Cathode; Ag+ + e = Ag E = +0.80 volts
The net reaction will be Cu + 2Ag+ = Cu+2 + 2Ag
Thus, the voltage will be
= +0.80 - (+0.34)
Answer:
4
Explanation:
Avogadro’s number represent the number of the constituent particles which are present in one mole of the substance. It is named after scientist Amedeo Avogadro and is denoted by .
Also, it is the number of particles in exactly 12.000 g of isotope carbon 12.
Avogadro constant:-
Hence,
Mass of = 131.293+ n18.998 g
So,
molecules have a mass of 131.293+ n18.998 g
Also,
molecules have a mass of g
So,
molecules have a mass of g
Also, given mass = 0.172 g
Thus,
<u>Thus, value of n is 4.</u>
Answer:
Respiración anaerobica
Explicación:
Las nuevas especies carecen de mitocondrias, por lo que realizan respiración anaeróbica porque en las mitocondrias solo ocurre la respiración aeróbica mientras que la respiración anaeróbica ocurre en el citoplasma de la célula. Trabajar en armonía es muy importante para el funcionamiento normal de su cuerpo. Por ejemplo, el funcionamiento combinado del sistema circulatorio y excretor. ambos sistemas hacen su trabajo mutuamente y por eso hay armonía en el cuerpo.
