4. how is the reaction of photosynthesis?
Jawaban:
Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH. During the second stage, the light-independent reactions use these products to capture and reduce carbon dioxide.
5. What are the products of the reaction between lithium and water ?
Jawaban:
Lithium reacts intensely with water, forming lithium hydroxide and highly flammable hydrogen. The colourless solution is highly alkalic. The exothermal reactions lasts longer than the reaction of sodium and water, which is directly below lithium in the periodic chart.

10. 28. Which does NOT change with time for a first-order reaction? (A) the amount of reactant that disappears in each half- life (B) the concentration of the reactant (C) the length of each half-life (D) the rate of the reaction
Pada reaksi order pertama yang tidak mengalami perubahan adalah :
C. The length of each half-life
Pembahasan
Reaksi orde pertama adalah reaksi dalam orde menetap, laju reaksi berbanding lurus dengan konsentrasi salah satu reaktan. Reaksi orde pertama sering memiliki bentuk umum A → produk. Tingkat diferensial untuk reaksi orde pertama adalah sebagai berikut:
laju=−Δ[A]/Δt=k[A]
Jika konsentrasi A digandakan, laju reaksi menjadi dua kali lipat, jika konsentrasi A dinaikkan dengan faktor 10, laju reaksi meningkat dengan faktor 10, dan seterusnya. Karena satuan laju reaksi selalu mol per liter per detik, satuan konstanta laju orde pertama adalah detik timbal balik (s−1). Hukum laju terintegrasi untuk reaksi orde pertama dapat ditulis dalam dua cara yang berbeda: satu menggunakan eksponen dan satu menggunakan logaritma. Ingat bahwa hukum laju terintegrasi memberikan hubungan antara konsentrasi reaktan dan waktu.

11. What are the three properties of waves?
Jawaban:
They can be transverse or longitudinal. However, all waves have common properties—amplitude, wavelength, frequency, and speed. Amplitude describes how far the medium in a wave moves. Wavelength describes a wave's length, and frequency describes how often it occurs.

15. explain the mechanism of conduction of electricity in a metal conductor
Jawaban:
explain the mechanism of conduction of electricity in a metal conductor = Jelaskan mekanisme penghantaran listrik pada penghantar logamPenjelasan:
Penghantar listrik (konduktor) adalah suatu material yang mudah menghantarkan arus listrik. Sifat hantarannya adalah memindahkan elektron-elektron dari satu titik kelistrikan ke titik kelistrikan lainnya secara mudah. Kegunaan utama dari penghantar listrik adalah mengalirkan arus listrik.[1] Penghantar listrik memiliki inti atom dengan elektron yang terikat secara lemah dan dapat bergerak secara bebas. Proses penghantaran listrik terjadi ketika material yang bermuatan positif dihubungkan dengan penghantar listrik. Interaksi yang timbul ialah perpindahan elektron dari penghantar listrik ke material yang bermuatan positif.[2] Pengaliaran arus listrik secara mudah melalui penghantar listrik disebabkan kandungan muatan listrik mudah bergerak saat timbul medan listrik meski dalam jumlah yang sangat kecil. Medan listrik pada penghantar bernilai nol selama tidak teraliri listrik.[3]
