Question

Answer 1

Bài 4:

\(\%O=100-63,53-8,23=28,24\%\)

\(CTHH\) dạng chung \(Ag_xN_yO_z\)

\(m_{A_g}=170.63,53\%\approx108\\ \Leftrightarrow108x=108\Leftrightarrow x=1\)

\(m_N=170.8,23\%\approx14\\ \Leftrightarrow14y=14\Leftrightarrow y=1\)

\(m_O=170-108-14=48\\ 16z=48\Leftrightarrow z=3\)

\(\Rightarrow A_gNO_3\)

Answer 2

\(\text{Đ}\text{ặt}:CTTQ:Ag_xN_yO_z\left(x,y,z:nguy\text{ên},d\text{ươ}ng\right)\\ x=\dfrac{170.63,53\%}{108}=1\\ y=\dfrac{8,23\%.170}{14}=1\\ z=\dfrac{100\%-\left(63,53\%+8,23\%\right)}{16}=3\\ \Rightarrow CTHH:AgNO_3\)
