[单选题]
Consider the following reac5f8 azdr 4fb7qtions involving metals a*s12mktqdjb + o 6f 5nr5ii02nzm zyt8nd their aqueous nitrate solutionnt5mzjfir2s d+ykmo 5n6zi b*8t1q 02s:

	$XNO_3$	$Y(NO_3)_2$	$Z(NO_3)_2$
Metal X		No reaction	No reaction
Metal Y	Grey solid of metal X observed		No reaction
Metal Z	Grey solid of metal X observed	Pink solid of metal Y observed

Choose the correct order of the metals from the strongest oxidizing agent to the weakest?

A. is Z -Y - X
B. is X - Y - Z
C. is Y - X - Z
D. is Y - Z - X


参考答案:  B


本题详细解析:
Least reactive metal is the st. wfa;gg+w-c;a(ect ro dkmx 4k+/)xs rongest oxidizing agent/ weakest reducing agent. Z is the most reactive metal (can displace both X and Y), followed by Y(can only displkc. ;+t;)g(xx eso g r/+kw4df-aawm cace X), and lastly, X (cannot displace any).
