Answer:
86.85°C
Explanation:
K = °C + 273.15
360K − 273.15 = 86.85°C ≈ 87°C
Because if an electron was in an atom, it would allow two atoms to combine without exploding and disentigrating, therfore there would be no suck thing as nuclear fission (nuclear bomb)
Answer:
When the solution (with phenolphthalein) changes to colorless
Explanation:
When titrating with HCl is common to add phenolphthalein as an acid-base indicator.
Phenolphthalein is pink or fucsia when added into a basic solution. On the other hand when it is in acid solutions, is colorless.
So, when titrating, the NaOH solution will be initialy pink due to the phenolphthalein and when reaching the equivalence point, that color will fade out into colorless. This is how you know you hace reached the equivalent point.
The characteristics of enzymes that give them this effectiveness as catalysts are they are made up of protein, they do not consume in the reaction ad lower the activation energy.
<h3>What is an enzyme?</h3>
The enzyme is a biological catalyst. The substrate is bound to them, and they supply the activation energy. It is the quantity of energy needed to initiate the reaction.
They are effective catalysts, as a small amount of them can affect a large amount of reaction.
Thus, enzymes are made of protein, do not consume in the reaction, and have reduced activation energy, which contributes to their efficiency as catalysts.
