Question

Mn giúp e vs ạ
1/ Hoàn Thành Phương Trình Phản Ứng:
a) P + ? -> P2O5
b) Fe2O3 + ? -> Al2O3 + Fe
c) Na + Cl2 -> ?
d) Cu + AgNO3 -> ? + Ag
e/ Al + ... -> AlCl3

Answer 1

\(a,4P+5O_2\xrightarrow{t^o}2P_2O_5\\ b,Fe_2O_3+2Al\xrightarrow{t^o} Al_2O_3+2Fe\\ c,2Na+Cl_2\xrightarrow{t^o}2NaCl\\ d,Cu+2AgNO_3\to Cu(NO_3)_2+2Ag\\ e,2Al+3Cl_2\xrightarrow{t^o}2AlCl_3\)

Answer 2

\(4P+5O_2\underrightarrow{t^o}2P_2O_5\)

\(Fe_2O_3+2Al\rightarrow2Fe+Al_2O_3\)

\(2Na+Cl_2\rightarrow2NaCl\)

\(Cu+2AgNO_3\rightarrow Cu\left(NO_3\right)_2+2Ag\)

\(2Al+3Cl_2\rightarrow2AlCl_3\)
