2.00 moles of CO2 and 1.50 moles of H2 are placed into a rigid 5.00-L container and they react according to the equation CO2(g)

+ H2(g) ⇄ CO(g) + H2O(g) K = 2.50 What will be the concentration of carbon monoxide when equilibrium is reached? 0.191 M 0.091 M 0.209 M (Your correct answer) 0.913 M 1.05 M

Answer: 0.209 M

Explanation:

Moles of  CO_2 = 2.00 mole

Moles of  H_2 = 1.50 mole

Volume of container = 5.00 L

Initial concentration of CO_2 = \frac{moles}{Volume}=\frac{2.00mol}{5.00L}=0.400M

Initial concentration of H_2 = \frac{moles}{Volume}=\frac{1.50mol}{5.00L}=0.300M

The given balanced equilibrium reaction is,

                         CO_2(g)+H_2(g)\rightleftharpoons CO(g)+H_2O(g))

Initial conc.          0.400 M          0.300M             0 M        0 M

   At eqm. conc.     (0.400-x) M   (0.300-x) M   (x) M      (x)  M

The expression for equilibrium constant for this reaction will be,

K_c=\frac{[CO]\times [H_2O]}{[H_2]\times [CO_2]}

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

2.50=\frac{[x]\times [x]}{[0.300-x]\times [0.400-x]}

By solving the term 'x', we get :

x = 0.209 M

Concentration of CO at equilibrium = x M  =  0.209 M

A box contains identical balls of which 12 are red, 18 white and 8 blue. Three balls are drawn from the box one after the other
svet-max [94.6K]

Answer:

a) 12/323

b) 8/233

Explanation:

a) The probability of a red ball being drawn is 12/38, or in a simplified fraction, 6/19. To find the probability that 3 are red you would multiply the probability of the fraction for each, except subtracting one from the total each time as the drawn is done without replacement. This is done as follows: 6/19 × 6/18 × 6/17= 12/323

b) The probability of drawing a blue ball is 8/38, or 4/19. To find that the first one is blue and the rest are red, the equation is done as follows: 4/19 × 6/18 × 6/17 = 8/233

(hopefully I did this right)

How is it possible to predict the type of bond that is likely to be found in a substance? what types of atoms generally form ion
Alenkasestr [34]
Using electronegativity difference is a good guide to the ionic/ covalent nature. Large differences indicate greater ionic character, small differences more covalent character. The larger the difference in electronegativity the more ionic properties a bond is said to have. The smaller the difference in electronegativity the more covalent properties a bond is said to have. 
Ionic bonding is formed through electrostatic attraction between a cation and anion. Foe example, Sodium fluoride has ionic bonding because it is composed by sodium and Fluorine (a non metal). On the other hand, covalent bonding is characterized by atoms sharing pairs of electrons. For example; methane has covalent bonding; carbon has 4 valence electrons and hydrogen has 1; when they bond they have a total of 8 electrons and satisfies the octet rule.
