At the equilibrium point in the decomposition of phosphorus pentachloride to chlorine and phosphorus trichloride, the following

Hitman42 [59]

Answer: $K_{eq}$ for the reaction is 5.55

Explanation:

Equilibrium constant is the ratio of the concentration of products to the concentration of reactants each term raised to its stochiometric coefficients.

The given balanced equilibrium reaction is,

$PCl_5(g)\rightleftharpoons PCl_3(g)+Cl_2(g)$

At eqm. conc. (0.010) M (0.15) M (0.37) M

The expression for equilibrium constant for this reaction will be,

$K_c=\frac{[Cl_2]\times [PCl_3]}{[PCl_5]}$

Now put all the given values in this expression, we get :

$K_c=\frac{(0.37)\times (0.15)}{(0.010)}$

$K_c=5.55$

Thus the $K_{eq}$ for the reaction is 5.55

How many atoms are in 766.3 grams of Li?

34kurt

1 mol of any substance is made of 6.022 x 10²³ units, these units could be atoms making up elements or molecules making up a compound.

In this case. 1 mol of Li is made of 6.022 x 10²³ atoms of Li

The molar mass of Li is 6.94 g/mol

Therefore mass of 1 mol of Li is 6.94 g

In 6.94 g of Li there are - 6.022 x 10²³ atoms

Then in 766.3 g of Li there are - 6.022 x 10²³ atoms / 6.94 g x 766.3 g = 665 x 10²³

There are 6.65 x 10^25 atoms of Li

Please help me I will do anything can you please show your work

oee [108]

Answer:

(1) 720 seconds (2) 10800 seconds (3) 17 dozens (4) 1.45 x $10^{25}$ (5) 13.29 moles

Explanation:

(1) 720 seconds

1 minute = 60 seconds

12 minutes = 720 seconds (12 x 60)

(2) 10800 seconds

1 hour = 60 minutes 1 minute = 60 seconds

3 x 60 = 180 minutes in 3 hours

180 x 60 = 10800 seconds in 180 minutes that are in 3 hours

(3) 17 dozens

1 dozen = 12

204 ÷ 12 = 17 dozens

(4) 1.45 x $10^{25}$

8.00 moles CO2 x $\frac{3 moles atoms}{1 moles CO2}$ = 24.0 moles atoms

24.0 moles x $\frac{6.022 × 10^{23} }{1 mole} }$ = 1.45 x $10^{25}$

(5) 13.29 moles

sorry but I'm not fully sure if this one is correct

8 x $10^{24}$ x $\frac{1 mole}{6.02 × 10^{23} }$ = 13.29 moles
