How many liters of a 3 M NaOH stock solution would you need to make 552 mL of a 105 mM NaOH dilution

0.01932 L

Explanation:

First we convert 105 mM to M:

Next we convert 552 mL to L:

Then we use the following equation:

Where:

We input the given data:

And solve for V₁:

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
