Calculate the mass percentage of potassium in K3PO4

Chemistry
1 answer:
Greeley [361]2 years ago
4 0

1) determine molar mass of K₃PO₄

=3(39.10)+30.97+4(16)\\=212.27\ g/mol

2) determine total mass of potassium atoms in K₃PO₄

=3(39.10)\\=117.3\ g

4) divide by molar mass and multiply by 100

=\frac{117.30}{212.27} × 100

= 55.25981062% (round as you wish)

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

Which role of water is significant for most living things in a biological system?a. It prevents many life processes from occurri
Sedaia [141]
I am pretty sure the correct answer is C.  Water has large heat capacity meaning it can absorb a lot of energy before changing temperature.  That helps the body regulate heat since it can be exposed to different environments and experience small temperature changes.

I hope this helps.  Let me know if anything is unclear.
