When determining the concentration of an acid solution, the titrant would usually be put in the burette while the analyte would be in the conical flask.

The titrant is usually a known solution while the analyte would be the unknown solution.

In order to determine the concentration of a solution of hydrofluoric acid, the acid would need to be titrated against a suitable base of known concentration using a suitable indicator to indicate the endpoint of the neutralization reaction.

Thereafter, the volume of the titrant used would be recorded and used to find the concentration of the acid (the analyte).

Thus, since the base would be known, it would be the one in the burette while the hydrofluoric acid would be the one in the conical flask.

How much heat is absorbed/released when 25.00 g of NH3(g) reacts in the presence of excess O2(g) to produce NO(g) and H2O(l) acc
Novay_Z [31]

Answer:

429.4 kJ are absorbed in the endothermic reaction.

Explanation:

The balanced chemical equation tells us that 1168 kJ of heat are absorbed in the reaction when 4 mol of NH₃ (g) react with 5 mol O₂ (g).

So what we need is to calculates how many moles represent 25 g NH₃(g) and calculate the heat absorbed. (NH₃ is the limiting reagent)

Molar Mass NH₃  = 17.03 g/mol

mol NH₃ = 25.00 g/ 17.03 g/mol = 1.47 mol

1168 kJ /4 mol NH₃  x 1.47 mol  NH₃ =  429.4 kJ

Shtirlitz [24]

Answer:

30 miles per gallon.

Explanation:

See picture  

When the amount of carbon is plotted based on efficiency, the following graph is obtained (see image)

when looking at the graph, it can be seen that the point of lowest emission is presented with the maximum possible efficiency, 30 miles per gallon and this value is 10400 pounds per 15000 cubic miles.
