What pressure would be exerted by 9.3 Newtons over a 48.9 m2 area?

When looking at the equilibrium between silver bromide and its aqueous ions, what could be added to solution to promote precipit

jeka57 [31]

Answer:

NaBr

Explanation:

When AgBr is dissolved in water, the following equilibrium is set up in solution;

AgBr(s)⇄Ag^+(aq) + Br^- (aq)

If we dissolve NaBr in the water, a common ion (Br^-) is now introduced into the system. This increases the concentration of Br^- and favours the reverse reaction hence more AgBr is precipitated. This is known as common ion effect.

What Phase is water at 120 degrees Celsius?

Rina8888 [55]

At atmospheric pressure water boils at 100 degC.
So the water would be gas/vapor/steam.

I am a metal which can be drawn into thin wires

Gwar [14]

Answer:

Silver and copper

Explanation:

Siliver

Electrical conductivity=62000000(s/m)

Boiling point=2162

Melting point=961.78

Phase=solid

Copper

Electrical conductivity=59000000(s/m)

Boiling point =2927

Melting point=1084.62

Phase=soild

Metals like gold, silver and copper are drawn into thin wire and are used in an electric circuit because of their high electrical conductivity

Mostly Siliver and copper are used since using gold is much expensive.

Iron has many isotopes but only 4 are found in significant amounts in naturally found mixtures. The amounts by mass percent are:

AnnZ [28]

Answer:

The average mass of iron to be is 54.76 amu.

Explanation:

Formula used to calculate average atomic mass follows:

$\text{Average atomic mass }=\sum_{i=1}^n\text{(Atomic mass of an isotopes)}_i\times \text{(Fractional abundance})_i$

1)

Mass of Fe-54 isotope = 53.9396 amu

Percentage abundance of Fe-54 = 5.845%

Fractional abundance of Fe-54 = 0.05845

2)

Mass of Fe-56 isotope = 55.9349 amu

Percentage abundance of Fe-56 = 91.754 %

Fractional abundance of Fe-56= 0.91754

3)

Mass of Fe-57 isotope = 56.9354 amu

Percentage abundance of Fe-57 = 2.119%

Fractional abundance of Fe-57 = 0.002119

4)

Mass of Fe-58 isotope = 57.9333 amu

Percentage abundance of Fe-58 = 0.282%

Fractional abundance of Fe-58 = 0.00282

Average atomic mass of iron :

$=53.9396 amu\times 0.05845+55.9349 amu\times 0.91754 +56.9354 amu\times 0.002119 + 57.9333 amu\times 0.00282=54.76 amu$

The average mass of iron to be is 54.76 amu.

Calcular la normalidad de 1 Kg de sulfuro de aluminio en 5000 ml de solucion.

Troyanec [42]

Calculate the normality of 1 Kg of aluminum sulfide in 5000 ml of solution.

Normality comes out to be 8.11

<h3> Given </h3>

Mass of solute: 1000g
Volume of solution (V): 5000 ml = 5 liters
Equivalent mass of solute (E) = molar mass / n-factor

n-factor for $Al_{2}S_{3}$ is 6 and molar mass is 148g

So, on calculating equivalent mass is equal to 24.66g

FORMULAE of Normality (N) = (Mass of the solute) / (Equivalent mass of the solute (E) × Volume of the solution (V)

N= $\frac{1000}{24.66*5}$

Therefore, normality of 1 kg aluminum sulfide is 8.11
