for a neutralization reaction, would you expect the magnitude of q to increase, decrease, or stay the same if the concentration
ikadub [295]

For a neutralization reaction, the value of q(heat of neutralization) is doubled when the concentration of only the acid is doubled.

A neutralization reaction is a reaction in which an acid reacts with a base to yield salt and water. Ionically, a neutralization reaction goes as follows; H^+(aq) + OH^-(aq) ------> H20(l).

The heat of neutralization (Q) of the system depends on the concentration of the solutions. Since Q is dependent on concentration, if the concentration of any of the reactants is doubled, more heat is evolved hence Q is doubled.

What is the total number of moles of H2SO4 needed to prepare 5.0 liters of a 2.0 M solution of H2SO4
forsale [732]
The molarity of H2SO4 is the number of moles in 1 L of solution.
The molarity is 2.0 mol/L
This means that there should be 2 moles in a 1 L solution to make up this molarity.
In this case we need to make up a 5 L solutions with that molarity. Then the amount of moles required are - 2 mol/L x 5 L = 10 mol

Why is it difficult to accurately predict leads most common isotope?
Hoochie [10]
Isotopes are the atoms of the same element with the difference in the number of neutrons. The number of electrons and protons are the same. The atomic masses are slightly different but the atomic number is the same. ... Therefore, it becomes difficult to exactly predict the common isotope of lead.
