Which of the following statements about the reaction quotient, Q is false? a. The value of Q can be used to predict equilibrium
irakobra [83]

Answer:

The correct statements are :b, c , d, and e.

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as K_{eq}

K is the constant of a certain reaction when it is in equilibrium, while Q is the equilibrium quotient of activities of products and reactants at any stage other than equilibrium of a reaction.

  • Q_c, reaction will move in forward direction and concentration of products will increase.
  • Q_c>K_c, reaction will move in backward direction and concentration of reactant will increase.
  • Q_c=K_c reaction is at equilibrium.

What is the density of an object that has a mass of 149. 8 g and displaces 12. 1 ml of water when placed in a graduated cylinder
kozerog [31]

Answer:

<h2>12.38 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

d =  \frac{m}{v}  \\

m is the mass

v is the volume

From the question

m = 149.8 g

v = 12.1 mL

We have

d =  \frac{149.8}{12.1}  = 12.380165... \\

We have the final answer as

<h3>12.38 g/mL</h3>

Hope this helps you
