Câu 15: Khử hỗn hợp X gồm CuO, FeO bằng khí CO sau một thời gian thu được 14,4 gam hỗn hợp rắn A (4 chất) và thoát ra 3,36 lít (đktc) khí B có tỷ khối so với H2 bằng 18. Hòa tan hoàn toàn A trong dung dịch H2SO4 đặc, nóng dư đến khi phản ứng kết thúc thu được 2,24 lít SO2 (đktc) và dung dịch B. a) Viết các phương trình phản ứng. b) Tính khối lượng mỗi oxit FeO, CuO trong hỗn hợp đầu. c) Cô cạn dung dịch B thu được bao nhiêu gam muối khan.

Microtubular fibers that assist in the movement of chromosomes during nuclear division in conjunction with proteins, makes up the small and large organelle pieces that assemble prior to translation three-base nucleotide sequence that can complementarily pair with the functional transcript, allowing a particular material to be brought to a ribosome particular time in the cell cycle when the cell’s systems determine if the cellular conditions are appropriate to continue through the cycle time in the cell’s cycle when proteins are made and organelles are duplicated enzyme that allows proper nucleotide bonding during transcription specific dna sequence which will initiate gene transcription division of the cell’s cytoplasm specific bond that forms between two amino acids when a carboxyl group binds to a amino group three-base sequence that does not code for a particular amino acid a paired organelle which facilitates the formation of movement microtubules time in the cell’s cycle when the microtubular structures exert an equal pressure on the cell’s genetic material
