3
dari reaksi : CuSO4(aq) + Zn(s) → Cu(s) + ZnSO4(aq)
4. Pembakaran sempurna 4 gram metana membentuk gas karbon dioksida dan air pada
keadaan standar menghasilkan 55,625 kJ. Tentukan entalpi pembakran molar stnadar
metana!
5. Sebanyak 0,58 gram gas butana dibakar dalam sebuah calorimeter bom yang berisi 500
ml air dengan suhu 30° C. setelah reaksi, suhu air dalam Kalorimeter naik
menjadi43,7° C. jika kapasitas kalor calorimeter diabaikan,sedangkan kalor jenis air
adalah 4,18 J/g° C, tentukan entalpi pembentukan butana
