The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension. I think the correct answer is option A. H2O will have the highest surface tension due to the hydrogen bonds that are present. Hope this answers the question. Have a nice day.

38.0 mL of a 0.026 M solution of HCl is needed to react completely with a 0.032 M NaOH solution. Calculate the number of moles o

svet-max [94.6K]

Answer:

The number of moles of HCl actually present is 0.000988

Explanation:

The balanced chemical equation of the given reaction is 

$HCl+NaOH \rightarrow NaCl+H_2 O$

Here one mole of HCl reacts with one mole of NaOH to form one mole of NaCl and one mole of water. Here the molarity of HCl is given as 0.026M.

molarity of NaOH is 0.032M 

molarity is the number of moles per unit volume of solution.

we have to calculate the number of moles in 36 mL of HCl.

38 mL=36/1000=0.038L 

the number of moles in 38 mL of HCl is given by 

no of moles = $0.026 \times 0.038=0.000988$
