What volume is occupied by a 0.118 mol of helium gas at a pressure of 0.97 atm and a temperature of 305 K ? Would the volume be
Naddika [18.5K]

Answer:

See below

Explanation:

PV = n RT        R = .082057  L - Atm / (K-Mole)

.97 V = .118 (.082057)(305)    

    V = 3.04 liters

Will not change for argon.....will be the same for all ideal gases

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.

Consider a solution that is 0.05 M HCl. Your goal is to neutralize 1 L of this solution (i.e. bring the pH to 7). You also have
Ilia_Sergeevich [38]

Answer:

The volume of NaOH required is - 0.01 L

Explanation:

At equivalence point ,

Moles of HCl = Moles of NaOH

Considering :-

Molarity_{HCl}\times Volume_{HCl}=Molarity_{NaOH}\times Volume_{NaOH}

Given  that:

Molarity_{NaOH}=5\ M

Volume_{NaOH}=?\ L

Volume_{HCl}=1\ L

Molarity_{HCl}=0.05\ M

So,  

Molarity_{HCl}\times Volume_{HCl}=Molarity_{NaOH}\times Volume_{NaOH}

0.05\times 1=5\times Volume_{NaOH}

Volume_{NaOH}=\frac{0.05\times 1}{5}=0.01\ L

<u>The volume of NaOH required is - 0.01 L</u>
