Answer:
lol I hate chemical but let me give some advice
Explanation:
Please go on Khan Academy or look at your notes and I promise you can figure out! Seriously, I am trying to be helpful not like the annoying teacher that says "figure it out"
The gain or loss of heat energy is what makes a reaction either endothermic or exothermic. A reaction is said to be endothermic if it absorb heat from the environment while a reaction is described as exothermic if it gives out heat to the environment. During chemical reaction, the bond energy of the reactants needs to be broken and new bond has to be formed in the products. The formation and breaking of bonds requires energy,
It is a good thing that you already have answered the first question. Now, moving on to the second question, there exist an equation for the neutralization of acid by a base that is shown below,
M₁V₁ = M₂V₂
Now, all the variables in the equation are given except for our unknown which is the V₂. Substituting the known values from the given above,
(0.1 M)(25 mL) = (0.05 M)(V₂)
The value of V₂ from the equation above is 50 mL. Therefore, 50 mL of 0.05 M NaOH solution will be needed to completely react with HNO3.
