氢化亚铜（CuH）是一种不稳定物质，能在氯气中燃烧；也能与酸反应，用CuSO4溶液和“某物质”在40-50℃时反应可产生它．下列有关叙述中错误的是（ ）
A．这“某物质”具有还原性
B．CuH与盐酸反应，可能产生H2
C．CuH与足量的稀硝酸反应：CuH+3H++NO3-=Cu2++NO↑+2H2O
D．CuH在氯气中燃烧：CuH+Cl2=CuCl+HCl
A、因在该反应中，铜的化合价降，则“某物质”中元素的化合价必升高，体现了还原性，故A正确；
B、因CuH中-1价的H可以与盐酸中+1价氢发生归中反应：CuH+HCl═CuCl+H2↑，故B正确；
C、因CuH具有还原性，与硝酸发生氧化还原反应：CuH+3HNO3=Cu（NO3）2+NO↑+2H2O，离子方程式：CuH+3H++NO3-=Cu2++NO↑+2H2O，故C正确；
D、因氯气的具有强氧化性，能够将+1价的铜氧化成+2价：2CuH+3Cl2=2CuCl2+2HCl，故D错误；
故选：D．
