A Chemical Natural Phenomenon: Rusting of Irons

Rusting of Irons (Fe) Let's talk about natural phenomenons. They are reactions (or called: phenomenons) that occur naturally, catalyzed by nature. Here, I'd like to explain to you about one of the more chemical natural phenomenons: rusting of irons. Rust is an iron oxide, usually colored red, which is a product of a redox reaction between iron and oxygen in the presence of water or air moisture. It consists of the chemical element  Fe 2 O 3 · n H 2 O , FeO(OH), and Fe(OH) 3. Rusting is a spontaneous process, which means that it occurs naturally without needing outer energy given into it. If there's enough oxygen and water around it, given enough time, rust will form and completely covers the whole iron. Irons with rust aren't as strong as their original counterparts, they are really flaky and weak. Now, let's see the process in a more chemical way!

24th of January 2019. At that date, my school, 3 Senior High School, held an event named Edu Passion. It is a kind of a fair where universities all around Indonesia promote themselves to attract senior high school students to continue studying there, which is held annually. You can see my video blog of the last year's Edu Passion.This year's Edu Passion is named "Agranasta." The opening ceremony were held in the morning, participated by the 12th grade students. Ridwan Kamil, our governor, attended it! It was held at the central field where we do our usual ceremonies every Monday. Around 9am, the real event starts! Stands started opening up, and the whole event was open for public! There were a lot of students from other schools who came to our school just to check out our education fair. It's like an important activity for us because we can take a break from studying and have a moment for us to decide our future: that is, studying at university. I visited a

Recommendation Letter for My Friend

(This is a recommendation letter I wrote to fulfill the task I got from Ms. Wiwin) To Adelaide Scholarships International scholarships, I am writing a letter on behalf of Mohamad Fadhlan Miftah Firdaus, a student of Senior High School 3 Bandung who is applying for the scholarships you offered. I have known him since August 2017. I've had the pleasure of having a chance to be able to supervise him as his homeroom teacher. Now, he is in the 12th grade right now. Fadhlan is someone who is able to tackle every kind of problem in a cool-headed way. He is able to stay calm even under great pressure. He is the leader of one of our senior high school's best extracurricular group, that is KPA3.  He has achieved some award in it, one of the best one is when his team went on to win the 2nd place in the Angklung Music Competition in 2018. He directed his team through a lot of hard work and constant practice and the result surely didn't lie. In addition to that, his grades in schoo

Me and My Dreams

~Background Hi everyone! My name is Marchotridyo, people usually call me Marcho. My closer friends either call me by 'Aco' or just simply call me by one word: "Mar" or "Cho".  I was born on the 1st of March 2002, in the city of Bontang, that is in East Kalimantan. So, I'm now 17! I'm the third child in my family, so I have 2 older brothers. Both of my brothers now work in Singapore at Shopee, and they're both graduates from STEI ITB. My family consists of me, my older brother, Rangga, my oldest brother, Inov, my mom and my dad. Although, now, in the time of writing this, I'm only home with mom because both of my brothers are working in Singapore and my dad is working over at Bontang again. I've lived in many different part of Indonesia before. I only lived at Bontang for a short amount of time, under 2 years. Then, I went and moved to Makassar which is located in South Sulawesi because my dad got moved to a different office. I lived

Analytical Exposition Text

Hello! In this post, I will publish the exposition I made for the test on Wednesday, October 10. It's about how school uniforms are really important especially for us in Indonesia. I hope you like it, and hopefully it can give some positive informations from it. Enjoy it, just like I enjoyed making this text! Are School Uniforms Really Necessary in Indonesia?                 Indonesia, one of the most populous country in the world. In a country very populated like it, you might think it will be hard to recognize people’s occupations because of all the diversities the people have between them. But, actually, it’s pretty easy to recognize who are students that go to school, because they all wear similar – if not same – school uniforms. You can also identify which stage of education they are sitting at right now because each stages of education has a different uniform. It also serves other purposes, such as a sign of discipline, a sign of unity, as a way to introduce professiona
