What will happen to the following equilibrium if Cl2
REY [17]

The following equilibrium will shift in the direction of the product:

<h3>Further explanation</h3>

Given

Reaction

4HCl + O₂ → 2H₂O + 2Cl₂

Cl₂  was removed

Required

Equilibrium changes

Solution

Reaction = - action

adding the products ⇒ Shifts in the direction of the reactants

reducing the products ⇒Shifts in the direction of the products

Cl₂ as a product, so if Cl₂ is taken or reduced, the reaction will try to maintain system equilibrium by moving to the right (product formation) ⇒ Shift in the direction of the product:

What mass of powdered drink mix is needed to make 0.5 M solution of 100 ml
Vladimir [108]

Answer:

There is 17,114825 g of powdered drink mix needed

Explanation:

Step 1 : Calculate moles

As given, the concentration of the drink is 0.5 M, this means 0.5 mol / L

Since the volume is 100mL, we have to convert the concentration,

⇒0.5 / 1   =  x /0.1    ⇒ 0.5* 0.1  = x = 0.05 M

This means there is 0.05 mol per 100mL

e

Step 2 : calculate mass of the powdered drink

here we use the formula n (mole) = m(mass) / M (Molar mass)

⇒ since powdered drink mix is usually made of sucrose (C12H22O11) and has a molar mass of 342.2965 g/mol.

0.05 mol = mass / 342.2965 g/mol

To find the mass, we isolate it ⇒0.05 mol * 342.2965 g/mol = 17,114825g

There is 17,114825 g of powdered drink mix needed
