1. is an aqueous solution of sodium bicatbonate NaHCO2 acidic ,basic ,or neutral??
The anion undergoes hydrolysis to give free OH- ions and the acid in aqueous solution.
Reaction:
NaHCO₃ + H₂O → H₂CO₃ + OH⁻ + Na⁺
Since carbonic acid is a weak acid, it remains undissociated, thus the solution becomes basic due to the presence of additional OH- ions produced by hydrolysis.

10. Change into pasive voice? Scientist classify glass as a solid
Change into pasive voice?
Scientists classify glass as a solid
Jawaban:
A glass as a solid is classified by scientists
Penjelasan:
Penggunaan VERB 1 (classify) setelah Subjek menunjukkan bahwa kalimat tersebut adalah Present Tense yg memiliki pola
* Active:
(+) S + VERB 1 (-s/es) + O
= Scientists + classify + glass as a solid
(Para Ilmuwan mengklasifikasikan gelas sebagai padatan)

Karena VERB 1 = classify
Maka Subjek seharusnya jamak scientist(S)
(Subjek jamak) Scientists + Classify
(Subjek tunggal) Scientist + Classifies

(+) S + is/am/are + VERB 3 + by
= A glass as a solid + is + classified + by scientists
(Gelas sebagai padatan diklasifikasikan oleh para ilmuwan)
