After Alea and his team studied hard enough, the day finally arrived, Alea and his team advanced as representatives of DKI Jakarta Province in the National Science Competition (KSN) held on the Island of the Gods of Bali. carries with the theme "Science Recover the Country" , covering the fields of Mathematics, Physics, Chemistry, Informatics/Computer, Astronomy, Economics, Earth, Geography.
Nindy helps Alea check her readiness to follow KSN and prepare the items that Alea will bring to Bali.
While tidying Alea's clothes into Rangga's suitcase and Nindy asked Alea several questions in turn.
"The following acidity sequence of acetic acid derivative compounds starts from the most acidic?" asked Rangga while showing the picture shown in the book to his daughter.
Alea thought for a moment that he answered "II, I, III"
"Substituents that are more electronegative near the carboxyl group will increase the acidity of acetic acid derivatives. More electronegative substituents have an induction effect or have an electron cloud pull towards the substituent and this helps to facilitate the release of protons in the substituted acid so that it has a stronger acid character. O is indeed more electronegative than Br but O also binds H so that the pull of the electron O to C becomes weaker than Br itself. So the right answer is II > I > III" Alea explained.
"Good" said Rangga.
"Don't forget later in taking the vitamins yes, soon your schedule will be mensturasi so that later not dizzy, if your stomach cramps in the compress alone with warm water and relax. Okay?"
"Thank you very much, Brother Nindy"
"With one more thing, this is your favorite aromatherapy oil not to be left behind" Nindy gave it to Alea.
Alea smiled then accepted it, she put it in her bag.
"Yes it's almost noon time you're late" Nindy helped Alea put on her jacket.
"Thank you again Brother Nindy, pray for Lea" Alea hugged Nindy before she left.
"Yes we have left first yes, if you want to go home just ask my driver to take you" Rangga told Nindy.
"The look of Mr. Rangga, I brought a car with me" replied Nindy.
"Oh yes already, we go first yes" Rangga pulled his daughter's suitcase then stepped out of the princess' room, just a few steps Nindy called Rangga back.
"Pak Rangga"
Rangga turned towards Nindy "What's the matter Nin?" ask Rangga.
"This is for Mr. Rangga" Nindy provides health vitamins for Rangga, as a form of gratitude because thanks to Rangga his relationship with his family, especially his father has improved and his parents bless his relationship with Riyan, even Riyan's parents had met his parents in Surabaya.
"And this" Nindy also returned the key to the apartment owned by Rangga "I've moved the apartment" said Nindy, since his relationship with his father improved Mr. Setiadji returned all his facilities to his daughter, who was not involved in the operation, he even bought Nindy an apartment unit in an apartment owned by Rangga.
Rangga smiled, he was also happy with the happiness that Nindy felt and hoped that Nindy would not go wrong again. He stepped on his legs after his daughter, who was waiting for him in the car.
Rangga escorted Alea to the airport "Later father will follow, there is some work that I have to finish" Rangga hugged and kissed his daughter's head.
"Let's just calm, well, there are many friends of Lea and the accompanying teacher"
"Yes, be careful, do not forget to tell Daddy later" said Rangga gave his last kiss on his daughter's head.
He and other parents stared at the backs of their children who had started to enter the city to check in on planes and fly to Bali Island.
