Bài 1:
\(Đặt:S_xO_y\left(x,y:nguyên,dương\right)\\ \Rightarrow\dfrac{m_S}{m_O}=\dfrac{16}{24}\\\Leftrightarrow\dfrac{32x}{16y}=\dfrac{16}{24} \\ \Leftrightarrow32.24x=16.16y\\ \Leftrightarrow\dfrac{x}{y}=\dfrac{16.16}{32.24}=\dfrac{1}{3}\\ \Rightarrow\left\{{}\begin{matrix}x=1\\y=3\end{matrix}\right.\\ \Rightarrow A:SO_3\)

Bài 2:
\(ACO_3+2HCl\rightarrow ACl_2+CO_2+H_2O\\ B_2CO_3+2HCl\rightarrow2BCl+CO_2+H_2O\\ R_2CO_3+2HCl\rightarrow2RCl+CO_2+H_2O\\ n_{H_2O}=n_{CO_2}=\dfrac{0,448}{22,4}=0,02\left(mol\right)\\n_{HCl}=0,02.2=0,04\left(mol\right)\\ \Rightarrow m_{muối.clorua}=115-60.0,02+0,04.35,5=115,22\left(g\right)\)
