Answer:
Volume of HCl require = 6 mL
Explanation:
Given data:
Volume of HCl require = ?
Molarity of HCl solution = 1.60 M
Volume of NaOH = 48.0 mL
Molarity of NaOH = 0.200 M
Solution:
Formula:
M₁V₁ = M₂V₂
By putting values,
1.60 M×V₁ = 0.200 M×48.0 mL
V₁ = 0.200 M×48.0 mL/1.60 M
V₁ = 9.6 M .mL /1.60 M
V₁ = 6 mL
C. Change attitudes, beliefs, or values
Heat
Explanation:
if I hold a beaker during a reaction that is supposedly an exothermic reaction, I will feel that the heat of the beaker. In exothermic reaction, the environment becomes hotter at the end of the change.
- Exothermic reaction is a type of enthalpy change.
- In this kind of reaction, heat is liberated to the surroundings.
- Here, the surrounding becomes hotter at the end of the changes.
- Change in enthalpy is assigned a negative value as the sum of heat contents of products is less than that of the heat content of reactants.

The balanced reaction is: H2O2 -> H2O + (1/2) O2
However, this is a very awkward equation since it has a
coefficient in fraction form.
Another way to write this equation is:
2 H2O2 -> 2 H2O + O2
Hope this helps.
