Answer: short answer short 0.65 / 5.37

15% NaOH by mass is 15g of NaOH in (100-15)g of solution.

No. Of moles of NaOH in solution = 0.65

No of moles of Water in solution = 4.72

Mole Fraction =

(

(Moles of Solvent)

(Moles Of Solute)+(Moles of Solvent)

)

(

(Moles of Solvent)

Total Number Of Moles

)

= 0.65 / 5.37

= 0.121

Answer:

2. B.

Explanation:

The letter B represents the activated complex.

The activated complex is the intermediate that is formed between the states of reactants "F" and products "G".

Letter A represents the activation energy of the reaction, that is the difference in potential energy between the reactants "F" and activated complex "B".

Letter C represents the enthalpy change of the reaction, that is the difference in potential energy between products "G" and reactants "F".

Letter D represents the potential energy of products "G".

Letter E represents the potential energy of reactants "E".

How many moles of aluminum are needed to make 9 moles of molecular hydrogen? given the reaction: 2 al + 6 hcl → 2 alcl3 + 3h2 6

sergiy2304 [10]

1) Chemical equation

2Al + 6 HCl ---> 2Al Cl3 + 3 H2

2) molar ratios

2 mol Al : 3 moles H2

3) Proportion

2 mol Al / 3mol H2 = x / 9 mol H2

4) Solve for x

x = 9 mol H2 * 2 mol Al / 3 mol H2 = 6 mol Ag

Answer: 6 moles
