Answer: Option (d) is the correct answer.

Explanation:

An acid which gives only one hydrogen ion or H^{+} ions upon dissociation in an aqueous solution is known as a monoprotic acid.

Whereas when an acid gives two hydrogen or H^{+} ions upon dissociation in an aqueous solution is known as a diprotoc acid.

And when an acid gives three hydrogen or H^{+} ions upon dissociation in an aqueous solution is known as a triprotoc acid.

Therefore dissociation of the given acids in an aqueous solution will be as follows.

  H_{2}CO_{3} \rightarrow 2H^{+} + CO^{2-}_{3}

  H_{2}SO_{4} \rightarrow 2H^{+} + SO^{2-}_{4}

  H_{3}PO_{4} \rightarrow 3H^{+} + PO^{2-}_{4}

  HCl \rightarrow H^{+} + Cl^{-}

Hence, we can conclude that out of the given options, HCl is the monoprotic acid.

How many grams of CO2 gas are produced if 48<br> grams of CH4 gas are consumed?
NNADVOKAT [17]

Answer:

CH4 +2 O2 — CO2 +2 H2O

Now we see that for 1 mol i.e. 16 grams of methane results in 1 mol of CO2 or 44 grams of CO2.

That means for 3 moles of methane , we will obtain 3 moles of CO2 OR for 48 (3*16) grams of CO2 , we will obtain (44*3) 132 grams of CO2 .That's it….
