3. Write the equilibrium expression, K, for the following reactions. S8 (s)+O2 (g)SO2 (g)

1 answer:

8 0

The correct equilibrium expression would be one that has products over reactants, and to the power of their stoichiometric coefficient. Also, it would not include any liquids or solids.
The balanced reaction is S₈(s) + 8O₂ (g) --> 8SO₂(g)

The equilibrium expression for your balanced reaction is:
$\Large \sf K_c = \frac{[SO_2]^8_{equil}}{[O_2]^8_{equil}}$

A 3.20-mol sample of gas occupies a volume of 350. mL at 300.0 K. Determine the

nalin [4]

Answer:

$P \approx 225atm$

Explanation:

From the question we are told that:

Moles of sample n=3.20_mol

Volume V=350mL

Temperature T=300k

Generally the equation for ideal gas is mathematically given by

$PV=nRT$

$P=\frac{nRT}{V}$

$P=\frac{3.20*0.08206*300}{350*10^{-3}}$

$P=225.079atm$

$P \approx 225atm$

If after heating the reaction between magnesium and hydrochloric acid, the mass of the magnesium chloride and beaker is measured

Allushta [10]

Since the beaker was heated we can asume that only magnesium cloride is left in the beaker, therfore the difference between the beaker with magnesium chloride and the empty beaker give the mass of magnisium chloride:

$\text{mass MgCl}_2=massbeakerwithMgCl_2-mass\text{ emprty beaker =37.83 g - 33.95g = 3.8}8g$

How many moles are there in 3.612 x 1024 formula units of Na2SO4?

vitfil [10]

Answer:

<h3>Theanswer is 6 moles</h3>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

$n = \frac{N}{L} \\$

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

$n = \frac{3.612 \times {10}^{24} }{6.02 \times {10}^{23} } \\$

We have the final answer as

<h3>6 moles</h3>

Hope this helps you
