Fake Smile Bad Girl's
Someone similar to his past.
Along the way to class Billy unceasingly looks at Acha, Acha reminds him of his childhood friend.
Acha knew from earlier Billy was staring fixedly at him.
"Okay duh just see how he will like kayak, pity Alaska later he has a new rival" said aja while hitting the hand of Billy.
"Later to go home together, I'll wait in the parking lot with the others"
"And usually it always comes home" rained Acha and entered her classroom.
Acha sat in her chair located in the back, there was already Sandra who was playing her phone.
"There's no food on my laper"
Sandra took out a loaf of bread and a box of chocolate milk from inside her locker.
"Thank you monkey you're my best friend"
"Lantam that time mulu" said Sandra who returned to focus with her phone.
"Good day kids" Salam Bu Anggit their chemistry teacher.
"Good day too Ma'am" replied the disciples simultaneously.
"Emit a chemistry book open chapter 3 today we will study the reaction rate"
"Good ma'am" All the students started to open their books, except for two people back there who one focus on eating and one focus on playing the phone.
"Acha Sandra put down her bread first and her phone" Ms Anggit's orders are not to be denied.
"Bu we both had been punished by Pak narno around the field 20 times a round, then we were called by the principal, look at my cheek bruised and my Aunt torn because she slapped it defending told her son, let me eat we will not interfere with mother's learning" rain aja seduce Bu Anggit will allow her to eat.
"it's up to you but don't bother the other students who are studying"
"Mom will give you 20 minutes to learn the reaction rate, after which we will ask and answer to take the value"
The children began to focus on reading the reaction rate, 20 minutes had passed.
"Mu 20 minutes is too short for those of us who learn a chapter" Wawan protested.
"Explain why rising temperatures can speed up the rate of a reaction!" ask Bu Anggit.
Acha raised her hand to tell her she knew the answer.
"The increase in kinetic energy causes an increase in the frequency of collisions between reactant molecules so that they more quickly reach the maximum activation energy to react." Answer Acha confidently.
Bu Anggit was amazed to see Acha knowing the answer, since earlier when his friends focused on understanding the contents of the book Acha even delicious to eat the bread.
Bu Anggit nodded in a sign that Acha's answer was correct.
"Explain how to speed up a reaction!" tanya Bu Anggit read the second question.
"Bu Siska, Increase the concentration of reactant substances. Increasing the concentration of reactants is the same as adding reactant molecules. The addition of molecules causes the more frequent plants between molecules so that the reaction energy will occur faster.
"Siska's right" Bu Anggit gave Siska value.
"Well this is the last question, a chemical reaction takes 40 seconds to react at 20 degrees Celsius. It is known that each increase of 10 degrees, causing the reaction rate to be twice as fast as the pipe from the beginning. Determine how long it will take to react at 40 degrees!"
Sandra stood up from her seat, she picked up a marker and wrote her answer on the board.
"Calculate the difference in normal reaction time and when the temperature is raised:
⁇ t \= 40 – 20 \= 20 degrees centigrade
Reaction rate increase \= ⁇ t: 10 \= 2 times
t⁴⁰°C \= t²⁰°C x (½)² \= 40 x (½)² \= 40 x ¼\=10.
Bu Anggit checked Sandra's answer and it turned out to be true. Bu Anggit gave a handcuff to Sandra because of her intelligence.
Chemistry learning ends the next lesson is a sport just like in general boys will go out to change clothes while girls change clothes in the classroom.
