Determine the empirical formula for a compound that is 36.86% n and 63.14% o by mass. determine the empirical formula for a comp
nexus9112 [7]
<span>Mass of nitrogen = 14.0067
</span> Mass of oxygen = 15.9994
In this compound nitrogen = 36.86 / 14.0067 = 2.63 
<span>And oxygen = 63.14 / 15.9994 = 3.95 <span>
now we have: N----- 2.63 and O----3.95 
by dividing both with the smallest number we get

<span>O-------3.95/2.63 = 1.5
To get whole numbers we multiply both by 2

Consider the following reaction:
Kitty [74]

Answer : The value of equilibrium constant (Kc) is, 0.0154

Explanation :

The given chemical reaction is:

                        SO_2Cl_2(g)\rightarrow SO_2(g)+Cl_2(g)

Initial conc.    2.4\times 10^{-2}          0             0

At eqm.          (2.4\times 10^{-2}-x)   x              x

As we are given:

Concentration of Cl_2 at equilibrium = 1.3\times 10^{-2}M

That means,

x=1.3\times 10^{-2}M

The expression for equilibrium constant is:

K_c=\frac{[SO_2][Cl_2]}{[SO_2Cl_2]}

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

K_c=\frac{(x)\times (x)}{2.4\times 10^{-2}-x}

K_c=\frac{(1.3\times 10^{-2})\times (1.3\times 10^{-2})}{2.4\times 10^{-2}-1.3\times 10^{-2}}

K_c=0.0154

Thus, the value of equilibrium constant (Kc) is, 0.0154

Consider the balanced equation. 2HCl + Mg MgCl2 + H2 If 40.0 g of HCl react with an excess of magnesium metal, what is the theor
Serga [27]

Answer:

Theoretical yield of hydrogen is 1.11 g

Explanation:

Balanced equation, Mg+2HCl\rightarrow MgCl_{2}+H_{2}

As Mg remain present in excess therefore HCl is the limiting reagent.

According to balanced equation, 2 moles of HCl produce 1 mol of H_{2}.

Molar mass of HCl = 36.46 g/mol

So, 40.0 g of HCl = \frac{40.0}{36.46}moles of HCl = 1.10 moles of HCl

Hence, theoretically, number of moles of H_{2} are produced from 1.10 moles of HCl = (\frac{1}{2}\times 1.10)moles=0.550moles

Molar mass of H_{2} = 2.016 g/mol

So, theoretical yield of H_{2} = (0.550\times 2.016)g=1.11g
