LHI
ya Mari kita jawab soal-soal tersebut
ya untuk yang akhir-akhir teman-teman
sudah ada yang tahu mungkin sudah
dijelaskan di sekolah
[Musik]
yang ah namanya KCL itu adalah kalium
klorida Nah karena senyawa ini terbentuk
dari atom logam dan nonlogam Maka
penamaannya langsung
menuliskan logamnya kalium nonlogam nya
kan klorin yang diambil keluarnya saja
Kemudian diakhiri dengan
Ida ya jadi namanya kalium klorida
Oke sudah jelas kita coba yang b apa
namanya
K2O namanya adalah kalium oksida
kemudian yang C
cacl2 namanya adalah kalsium klorida
yang deh apa namanya
ya betul namanya yang d adalah Nah itu
namanya adalah natrium
hidrida ya kemudian yang eh logam dengan
nonlogam juga
yah namanya img3 N2 adalah magnesium
nitrida ya asalnya kan n itu nitrogen ya
Jadi diambil suku kata pertamanya nit
nit er kemudian akhiri Ida jadi namanya
magnesium nitrida
kemudian yang F apa namanya
dayang F adalah
untuk albr3
namanya aluminium
bromida
untuk yang G Nah untuk yang G inikan
nonlogam dengan nonlogam ya cl2 Inikan
nonlogam
punya juga non logam Na untuk penamaan
nonlogam dengan nonlogam
setiap atom untuk jumlahnya itu diberi
suatu kode jumlah ya kita lihat dulu
untuk yang G namanya apa
ya yang gini biasanya sel dua Oh itu
adalah
diklorooksida Ya di itu artinya adalah
cellnya berjumlah dua jadi dikloro
kemudian Nyonya oksigen kita ambil satu
suku katanya yaitu ox kemudian diakhiri
dengan Ida diklorooksida
sampai sini sudah mulai jelas
ia bahkan sudah ada yang jelas banget ya
kita letak lanjutkan menjawab soal
berikutnya yang ha apa namanya
ya P 2 o 5 namanya adalah
[Musik]
difosfor pentaoksida
ya karena penyedot dua berarti di
a b itu fosforus kita ambil difosfor
saja
Kemudian untuk oksigennya berjumlah lima
jadi pentaoksida
sudah semakin jelas kita lanjut yang
iber2 O3 namanya apa ya betul namanya
adalah
br2 O3
di Brom
trioksida Yatri artinya oksigennya
berjumlah tiga
berikutnya yang J
B 3 ya namanya apa nih nonlogam dengan
nonlogam juga ya Bi itu boron jadi
langsung disebutkan saja boron karena
fc3 boron Tri Florida
yang Kak berikutnya cbr4 C Itu adalah
karbonnya jadi langsung disebutkan cbr4
adalah karbon tetrabromida t tak artinya
pr-nya berjumlah empat atom
dan yang terakhir hi ha itu kan hidrogen
cuman kalau dalam tata nama senyawa
kalau dia di depan bisa disebut dengan
asam ya Jadi yang LHI itu adalah asam
Ia adalah yodium menjadi iodida jadi
ingat kalau ada senyawa yang depannya H
itu bisa dinamakan dengan asam kemudian
disebutkan belakangnya jadi ini yang
untuk yang Hai namanya adalah asam
iodida
Oke Paham teman-teman sampai disini
untuk lebih paham lagi tentu teman-teman
perlu latihan soal-soal yang lain lagi
Oke sampai di sini dulu
Salam sukses selalu dan
belajar B
