Answer: as you add the base it added some PH. The Ph lever of white vinager is2.4 - 3.4
Answer:
4. K = [CF₂Cl₂] [HCl]² / [HF]² [CCl₄]
5. K = [NH₃] [HCl]
6. K = 1 / [SO₃]
Explanation:
Equilibrium constant expressions are defined as the ratio between concentrations of products and concentrations of reactants powered to its reaction quotient (Compounds in solid or liquid phase are not taken in the expression).
For the reactions:
4. CCl₄(g) + 2HF(g) ⇌ CF₂Cl₂(g) + 2HCl(g)
Equilibrium expression, K, is:
<em>K = [CF₂Cl₂] [HCl]² / [HF]² [CCl₄]</em>
5. NH₄Cl(s) ⇌ NH₃(g) + HCl(g)
<em>K = [NH₃] [HCl]</em>
6. SO₃(g) + H₂O(l) ⇌ H₂SO₄(l)
<em>K = 1 / [SO₃]</em>
Answer: 
molecules of 
Explanation: To calculate the moles, we use the formula:
Given mass= 55.0 g
Molar mass= 98g/mol
1 mole of contains =
molecules of
0.56 moles of contains =
molecules of
