Answer:
25.6mL NaOH
Explanation:
We are given the Molarity of the solution () and the volume of the solution (.02L).
By multiplying the two together, we can find the moles of solution that are reacted with HCl.
This gives us .0082 moles of HCl.
We then find the moles of NaOH that are needed to react with the HCl using the equation.
As HCl and NaCl have a 1:1 ratio, we need .0082 mol of NaOH.
Dividing this value by the Molarity of the solution
Gives us the answer, in Liters (.0256), which we can then divide by 100 convert to mL.
Explanation:
In a chemical reaction, the atoms do not change (like in radioactive reactions) but merely rearrange themselves to form new compounds by creating new bonds between atoms. If the bonds are of a lower energy state, this will be favoured in a chemical reaction because chemical reaction always seeks products with the lowest Gibbs free energy. Therefore spontaneous reactions will usually be those chemical reactions whose products are of a lower energy state than the reactants. These chemical reactions usually don’t need high activation energies to ‘jumpstart’ them.
