Explanation:

According to reaserch,

According to reaserch,An neutralization reaction can be defined as a chemical reaction in which an acid and base quantitatively react together to form a salt and water as products. In a neutralization reaction, there is a combination of H+ ions and OH– ions which form wa acid anhydride is an acid anhydride that is an organic compound.

Answer:

4054 kcal of heat is released during complete combustion of 354 g of octane.

Explanation:

Heat of combustion of 1 mol of octane is 1.308\times 10^{3} kcal

Molar mass of octane = 114.23 g/mol

We know, no. of moles = (mass)/(molar mass)

So, 1.308\times 10^{3} kcal of heat is released during complete combustion of 114.23 g of octane.

So, amount of heat is released during complete combustion of 354 g of octane = (\frac{1.308\times 10^{3}}{114.23})\times 354  kcal = 4054 kcal

Hence 4054 kcal of heat is released during complete combustion of 354 g of octane.

What is the molarity of a solution which has a volume of 3 litres and contains 5.1 moles of Br2?
katrin [286]

Answer:

The molarity of the solution is 1.7 \frac{moles}{liter}.

Explanation:

Molarity (M) or Molar Concentration is the number of moles of solute that are dissolved in a certain volume.

The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:

Molarity=\frac{moles of solute}{volume of the solute}

Molarity is expressed in units \frac{moles}{liter}.

In this case, you know:

  • moles of solute= 5.1
  • volume= 3 L

Replacing:

Molarity=\frac{5.1 moles}{3 L}

Solving:

Molarity= 1.7 \frac{moles}{liter}

<u><em>The molarity of the solution is 1.7 </em></u>\frac{moles}{liter}<u><em>.</em></u>
