The number of moles present in the FeSO4 are 0.055 mol.

<u>Explanation:</u>

The mass of a substance containing the same number atoms in 12.0 g of 12C is known as mole. One mole of any substance is equal to 6.023 x 10^23. The moles of a substance can be determined by using the formula,

Number of moles = mass in grams / molecular mass

Given,

mass = 8.36 g,

molecular mass of FeSO4 = 151.908 g / mol

number of moles = 8.36 / 151.908

= 0.055 mol.

In solid NaCl, the equilibrium separation between neighboring Na+ and Cl- ions is 0.283 nm. Calculate the coulombic energy betwe

const2013 [10]

Explanation:

It is given that r = 0.283 nm. As 1 nm = $10^{-9} m$ .

Hence, 0.283 nm = $0.283 \times 10^{-9} m$

Formula for coulombic energy is as follows.

$U_{coulomb} = -1.748 \frac{e^{2}}{4 \pi \epsilon_{o} r}$

where, e = $1.6 \times 10^{-19}$ C

$\epsilon_{o}$ = $8.85 \times 10^{-12}$

$U_{coulomb} = -1.748 \frac{(1.6 \times 10^{-19}^{2}}{4 \times 3.14 \times 8.85 \times 10^{-12} \times 0.283 \times 10^{-9}}$

= $1.423 \times 10^{-18} J$

As 1 eV = $1.6 \times 10^{-19} J$

So, 1 J = $\frac{1 eV}{1.6 \times 10^{-19}}$

Hence, U = $\frac{1.423 \times 10^{-18} J}{1.6 \times 10^{-19} J}$

= 8.9 eV

Also, 1 J = $\frac{10^{-3} kJ}{6.022 \times 10^{23}mol}$

= $1.67 \times 10^{-27}$ kJ/mol

Therefore, U = $1.423 \times 10^{-18} J \times 1.67 \times 10^{-27}$ kJ/mol

= $2.37 \times 10^{-45} kJ/mol$

A container of gas has a volume of 3.5 L and a pressure of 0.8 atm. Assuming the temperature remains constant, what volume of ga

vovikov84 [41]

<h3>Answer:</h3>

5.6 L

<h3>Explanation:</h3>

We are given;

Initial volume, V1 = 3.5 L
Initial pressure, P1 = 0.8 atm
Final pressure, P2 = 0.5 atm

We are required to calculate the final volume;

According to Boyle's law, the volume of a fixed mass of a gas and the pressure are inversely proportional at a constant temperature.

That is; P α 1/V
Mathematically, P=k/V
At two different pressure and volume;

P1V1 = P2V2

In this case;

Rearranging the formula;

V2 = P1V1 ÷ P2

= (0.8 atm × 3.5 L) ÷ 0.5 atm

= 5.6 L

Therefore, the resulting volume is 5.6 L

lianna [129]

Answer:

plasma

Explanation:

Plasmas are a lot like gases, but the atoms are different, because they are made up of free electrons and ions of an element such as neon (Ne). You don't find naturally occurring plasmas too often when you walk around. They aren't things that happen regularly on Earth.
