it will take 24 hours
**Bacterial cultures **expand exponentially . It grows by two times every 16 hours. The time taken to **triple **from its original size is 24 hours.
What is bacteria culture?
A **test **to influence whether you have a bacterial pathologic process is a bacterium culture . A sample of blood, feces, urine, skin, mucus or spinal fluid may be used for the test . The different types of bacteria culture are broth culture, stable culture, and agar process.
A **healthcare **professional can choose the most suitable course of therapy using this kind of test to **determine **what brought on the infection .
The culture of **bacteria grows **exponentially. Every 16 hours, the bacteria double its size. So, the bacteria population will **triple **in **24 hours. **
Thus, the **time taken **for the **bacteria **to become triple is 24 hours.

The bacteria will take approximately 24 hours to triple their size from the original population. This calculation is based on the fact that the bacteria double their size every 16 hours. Using exponential growth formulas, we derived this time requirement.

Jawaban:setarakan reaksi redoks ini menggunakan metode bilangan oksidasi (biloks). Reaksi: BrO₃⁻(aq) + Fe²⁺(aq) → Br⁻(aq) + Fe³⁺(aq) Langkah-langkah: 1. Tentukan Bilangan Oksidasi Setiap Atom:- BrO₃⁻: Br = +5, O = -2- Fe²⁺: Fe = +2- Br⁻: Br = -1- Fe³⁺: Fe = +32. Identifikasi Atom yang Mengalami Perubahan Biloks:- Br: +5 → -1 (Reduksi, penurunan biloks = 6)- Fe: +2 → +3 (Oksidasi, kenaikan biloks = 1)3. Setarakan Perubahan Biloks:- Kalikan perubahan biloks Fe dengan 6 agar sama dengan perubahan biloks Br.- Dengan demikian, kita butuh 6 ion Fe²⁺ dan 6 ion Fe³⁺.4. Tulis Ulang Reaksi dengan Koefisien yang Sudah Disetarakan:- BrO₃⁻ + 6Fe²⁺ → Br⁻ + 6Fe³⁺5. Setarakan Muatan:- Muatan kiri: -1 + 6(+2) = +11- Muatan kanan: -1 + 6(+3) = +17- Selisih muatan: +17 - (+11) = 6- Karena reaksi terjadi dalam suasana asam (tidak disebutkan basa), kita setarakan dengan menambahkan H⁺. Tambahkan 6H⁺ ke sisi kiri untuk menyetarakan muatan:- BrO₃⁻ + 6Fe²⁺ + 6H⁺ → Br⁻ + 6Fe³⁺6. Setarakan Atom Hidrogen dengan Menambahkan H₂O:- Tambahkan 3H₂O ke sisi kanan untuk menyetarakan hidrogen:- BrO₃⁻ + 6Fe²⁺ + 6H⁺ → Br⁻ + 6Fe³⁺ + 3H₂O7. Periksa Keseimbangan Atom Oksigen:- Sisi kiri: 3 atom O- Sisi kanan: 3 atom O- Atom oksigen sudah setara. Reaksi Setara: BrO₃⁻(aq) + 6Fe²⁺(aq) + 6H⁺(aq) → Br⁻(aq) + 6Fe³⁺(aq) + 3H₂O(l)
