Answer:

When a neutral atom gains one or more electrons it becomes negative ion also known as anion

For example

Cl+ e- -------> Cl-

O +2e- -------> O2-

Describe in general terms the structure of ionic solids such as nacl
allochka39001 [22]
<span>Ionic compounds are chemical compounds in which ions are held together in a lattice structure by ionic bonds. They have a high melting and boiling point, and they have a high hardness and are very brittle. The cations and anions are stuck together in a sense. So in this case, sodium (Na) is attracted to Chlorine (Cl).</span>

Which has the greatest mass? 1 mole Ca 1 mole CO 1 mole O2 1 mole CH4 1 mole NO
tino4ka555 [31]

Answer: 1 mole of Ca has the greatest mass.

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP , contains avogadro's number (6.023\times 10^{23}) of particles and weighs equal to the molecular mass of the substance.

1 mole of Ca has a mass of 40 g.

1 mole of CO has a mass of 28 g

1 mole of O_2 has a mass of 32 g

1 mole of CH_4 has a mass of 16 g.

1 mole of NO has a mass of 30 g.

Thus the greatest mass is of 1 mole of Ca

The Nernst equation at 20oC is:
saw5 [17]

Answer:

a. -58 millivolts

Explanation:

The given Nernst equation is:

E_{ion} = 58 millivolts /z \Big[ log_{10} \Big( \dfrac{[ion]_{out}}{[ion]_{in}}\Big) \Big]}

The equilibrium potential given by the Nernst equation can be determined by using the formula:

E_{Cl^-} = \dfrac{2.303*R*T}{ZF} \times log \dfrac{[Cl^-]_{out}} {[Cl^-]_{in}}

where:

gas constant(R) = 8.314 J/K/mol

Temperature (T) = (20+273)K

= 298K

Faraday constant F = 96485 C/mol

Number of electron on Cl = -1

E_{Cl^-} = \dfrac{2.303*8.314*298} {(-1)*(96845)} \times log \dfrac{100} {10}

E_{Cl^-} = - 0.05814  \ volts

\mathsf{E_{Cl^-} = - 0.05814  \times 1000 \  milli volts}

\mathsf{E_{Cl^-} \simeq - 58\   milli volts}
