Answer:H2SO4
Explanation:calcium forms a precipitate in a sulfide compound of so4
The formula of aspartame is <span>C14H18N2O5.
From the periodic table:
molecular mass of hydrogen = 1 grams
molecular mass of carbon = 12 grams
molecular mass of nitrogen = 14 grams
molecular mass of oxygen = 16 grams
This means that:
molar mass of aspartame = 14(12)+18(1)+2(14)+5(16) = 294 grams
Therefore, each 294 grams of aspartame contains 5(16) = 80 grams of oxygen. To know number of grams of oxygen in 23.6 grams of aspartame, simply use cross multiplication as follows:
mass of oxygen = (23.6x80) / 294 = 6.42 grams</span>

Answer:
B). The equivalence point is where the amount of acid equals the amount of base during any add-base titration.
Explanation:
Equivalence point -
During the process of titration of the neutralization reaction , like acid - base reaction .
In the titration process , the equivalence point is the point , when the amount of acid is equal to the amount of base .
In indicator used for th process is pH sensitive ,
It is not always necessary to have pH = 7 at the equivalence point ,
The titration curve is plotted for the pH v/s base .
Hence , from the given options , the correct statement is ( B ) .
