If the concentration of fluoride anion and aluminum cation was increased to 5 m, by how much would the measured ecell change?.

ladessa [460]

If the concentration of fluoride anion and aluminum cation was increased to 5M, then there would be decrease in Ecell by 0.055 volts

The standard reduction potential of Fluoride anion and aluminum cation are -

2Al -----> 2Al3+ + 6e- $E^o$ cell = +1.66

6e- + 3F2 -----> 6F- $E^o$ cell = +2.87

The complete reaction is -

2Al + 3F2 ------> 2Al3+ + 6F- $E^o$ = +4.53

Using Nernst Equation :-

E = $E^o$ – 0.0592/n*log[Al3+]^2[F-]^6

n = 6 (n = number of transferred electrons)

E = +4.53 - 0.0592/6*log(5)^2(5)^6

E = +4.53 - 0.00987*log(25)(1.56 x 10^4)

E = +4.53 – 0.00987*log(3.9 x 10^5)

E = + 4.53 -0.00987(5.59)

E = + 4.53 - 0.055

E = +4.47

The change in Ecell = 5 - 4.47 = 0.055V

Describe the bond between the solid particles

Zarrin [17]

Solids are generally held together by ionic or strong covalent bonding, and the attractive forces between the atoms, ions, or molecules in solids are very strong. In fact, these forces are so strong that particles in a solid are held in fixed positions and have very little freedom of movement.

hope it helps...!!!

use the density formula to solve the following problems. a sample of a substance has a volume of 60.5mL and a density of 1.20mL.

svetlana [45]

Answer:

mass of substance =50.4 g

Explanation:

Using the density formula;

Density = mass of substance / volume of substance

Therefore, making mass subject of the density formula,

mass of substance = volume of substance / density of substance

volume of substance = 60.5 mL, density = 1.20 g/mL ( since common units of density is either g/cm³ or g/mL)

mass of the substance = 60.5 mL / 1.20 g/mL

mass of substance = 50.4 g

Find the magnetic force experienced by a proton moving with the speed of 3 × 105 m/s in the magnetic field B of magnitude 6 × 10

Karo-lina-s [1.5K]

The magnetic force experienced by a proton moving with a speed of 3 × $10^{5}$ m/s in the magnetic field B of magnitude 6 × $10^{-5}$ T will be 2.88× $10^{-18}$ N.

Magnetic force can be defined as the attraction or repulsion force that arises between electrically charged particles due to the motion of the charged particles.

Given,

Speed = 3× $10^{5}$ m/s

Magnetic Field, B= 6 × $10^{-5}$ T

Magnetic force is the product of velocity, the charge of a proton, and the magnetic field present there.

The magnetic force can be represented as:

F=qvB

F=1.6× $10^{-19}$ ×3× $10^{5}$ ×6 × $10^{-5}$

F=2.88× $10^{-18}$ N

Hence, the magnetic force experienced by the proton will be 2.88× $10^{-18}$ N.
