Use the "x is small" approximation to find the concentration of the products in the following reaction which initially contains
Mrrafil [7]

Answer:

Concentration of product at equilibrium ;

[H^+]=0.0000229 M

[CN^-]=0.0000229 M

Explanation:

HCN(aq)\rightleftharpoons H^+(aq) + CN^-(aq)

initially

0.85 M        0    0

(0.85-x)M    x      x

The equilibrium constant of reaction = K_c= 6.17\times 10^{-10}

The expression of an equilibrium cannot can be written as:

K_c=\frac{[H^+][CN^-]}{[HCN]}

6.17\times 10^{-10}=\frac{x\times x}{(0.85-x)}

Solving for x:

x = 0.0000229

Concentration of product at equilibrium ;

[H^+]=0.0000229 M

[CN^-]=0.0000229 M

Many grams of aluminum are required to produce 3.5 moles Al2O3 in the presence of excess O2?
Aleks [24]
The  grams  of aluminum  that are required   to produce  3.5  moles of AlO3  in  presence of excess O2   is calculated as  below

write  the  equation for reaction
4 Al + 3O2 =2 Al2O3

by use of mole  ratio between  Al  to  Al2O3   which  is  4 :2  the moles of  Al 
=3.5 x4/2 = 7  moles

mass of Al  =  moles /   x molar mass

= 7 moles  x27 g/mol  =189  grams

The diameter of a hydrogen atom is 106 pm. Find the length in kilometers of a row of 4.34 x 1023 hydrogen atoms?
valina [46]

The length in kilometers of a row of 4.34 x 1023 hydrogen atoms is 4.34 x 10¹⁴ km.

<h3>Length of the entire hydrogen atoms</h3>

The length of the entire hydrogen atom is calculated as follows;

Length of the row = number x diameter of one

Length of the row = 4.34 x 10²³ x 10⁶ x 10⁻¹²

Length of the row = 4.34 x 10¹⁷ m

Length of the row = 4.34 x 10¹⁴ km

Thus, the length in kilometers of a row of 4.34 x 1023 hydrogen atoms is 4.34 x 10¹⁴ km.
