Pada reaksi pembakaran gas butena (C4H8) dengan gas oksigen akan menghasilkan gas karbon dioksida dan uap air dengan persamaan reaksi: C4H8(9) + O2(g) → CO2(g) + H2O (9) Maka perbandingan koefisien gas karbondioksida dan uap air adalah

To find the total cost of all items, we calculated the cost for each item individually. The final total comes to $7.09 after summing up all the individual costs. Each calculation was based on the specified rates for each item.

Jawaban:pertama, perlu disamakan reaksinya C4H8(9) + O2(g) → CO2(g) + H2O (9) C4H8 kita coba kasih koef. 1, jadinya koefisien CO2 disebelah harus 4 (kan C4 = 4C)dan H8 berarti disebelah harus 4 H2, jadi 4 H2OC4H8 + O2 -> 4 CO2 + 4H2OLalu O disebelah kanan sekarang ada 12, di kiri berarti 6 O2C4H8 + 6O2 -> 4CO2 + 4H2OPerbandingan koef. gas CO2 dan uap air = 4:4 = 1:1
