Assalamualaikum warahmatullahi wabarakatuh.

Alhamdulillah, puji syukur kami panjatkan ke hadirat Allah, atas selesainya

laporan praktikum kimia ini yang berjudul Pembuktian Hukum Kekekalan Massa dan

Hukum Perbandingan Tetap laporan iniditulis untuk melihat, mengkaji dan menelititentang hukum-hukum dasar kimia. Tujuan dari pembuatan laporan ini untukmemenuhi tugas praktikum kimia, meningkatkan ilmu dan mempraktikkan langsung

pengamatan terhadap zat-zat kimia.

Dalam penulisan laporan praktikum ini, tidak sedikit bantuan yang telah diberikan

oleh orang lain sehingga laporan ini dapat terselesaikan dengan baik dan tepat waktu.

Ucapan terimakasih kami sampaikan kepada,

o Orangtuao Guru pembimbing Kimia kelas X SMA Negeri 2 Cibinong, Ibu Tintin Sugiharti,o Teman-teman kelas X MIIA 1o Dan seluruh pihak yang telah membantuTiada gading yang tak retak, begitu pula dalam laporan praktikum ini yang masih

jauh dari sempurna. Mohon maaf apabila masih ada kesalahan dalam penulisan. Semoga
