The neutralization reaction is expressed as:
2KOH + H2SO4 = K2SO4 + 2H2O
We are given the volume and the concentration of the KOH that is used in the reaction. We use this and the relations from the reaction to determine the concentration of the acid.
0.150 mol KOH / L ( .025 L ) ( 1 mol H2SO4 / 2 mol KOH ) = 0.00188 mol H2SO4
Concentration of acid = 0.00188 mol / .015 = 0.125 M of sulfuric acid

When there is a decimal point, you must skip the zeros until you reach a number. Once you reach that number, you move 2 more places to the right of that number in order to have 3 significant figures. Hope this helps!
Answer:
The answer is : D. Wind energy
Explanation:
Aromatic nitrogen bonded to hydrogen, as found in pyrrole must be represented as [nH] ; thus imidazole is written in SMILES notation as n1c[nH]cc1 . When aromatic atoms are singly bonded to each other, such as in biphenyl, a single bond must be shown explicitly: c1ccccc1-c2ccccc2 .
