Answer:

Explanation:

An isotope is an atom that has a different number of neutrons than the standard for that atom.

1)Nitogen -14 has 7 protons in the nucleus for its an isotope of nitrogen which has an atomic number of 7.

2)Now we need to find the number of neutrons. This is implied in the name of the isotope whereby the protons and neutrons add up to its atomic number. So

(14-7 protons= 7 neutrons.)

So it has 7 neutrons.

If the reduction reaction has a reduction potential of 0.1 V, and the oxidation reaction has a reduction potential of -0.4V, and

aleksley [76]

Answer : The value of ΔG expressed in terms of F is, -1 F

Explanation :

First we have to calculate the standard electrode potential of the cell.

$E^o=E^o_{cathode}-E^o_{anode}$

or,

$E^o=E^o_{reduction}-E^o_{oxidation}$

$E^o=(0.1V)-(-0.4V)=+0.5V$

Now we have to calculate the standard cell potential.

Formula used :

$\Delta G^o=-nFE^o$

where,

$\Delta G^o$ = Gibbs free energy = ?

n = number of electrons = 2

F = Faraday constant

$E^o$ = standard e.m.f of cell = +0.5 V

Now put all the given values in this formula, we get the Gibbs free energy.

$\Delta G^o=-(2\times F\times 0.5)$

$\Delta G^o=-1F$

Therefore, the value of ΔG expressed in terms of F is, -1 F

If a substance melts at 20oC, what is its freezing point?

shutvik [7]

Answer:

It is difficult, if not impossible, to heat a solid above its melting point because the heat that ... in a solid are packed in a regular structure that is characteristic of that particular substance.
