1 赞成Will you have a picnic in the park?2 Neither can
neither意思是“也不”,用于句首,后接倒装句（也即疑问句语序）.3
used to表示过去常常发生的事情或过去持续存在的情况,其中的to是不定式的符号,后面用动词原形.often + 动词过去式 与 used to + 动词原形 意思相近.

原来硫酸为0.1*2.2=0.22mol,加入NaOH后到30ml才开始沉淀,说明硫酸有剩余,且剩余的摩尔数为0.03*2/2=0.03mol.所以反应的硫酸有0.19mol.反应生成的氢气为0.896/22.4=0.04mol,所以与Fe单质反应的硫酸有0.04mol,其余的0.15mol硫酸是和氧化铜和氧化铁反应的,最后的固体是纯铜,摩尔数为1.28/64=0.02mol,所以与氧化铜反应的硫酸为0.02mol,还有0.13mol是和氧化铁反应的,所以氧化铁的摩尔数为0.043mol.2Fe3+ Fe==3Fe2+,Fe+2H+==Fe2+ +H2,Fe+Cu2+==Fe2+ +Cu,所以FeSO4的摩尔数=0.043*2*1.5+0.04+0.02=0.19mol,所以浓度为1.9mol/L关于英语上面的问题,请把答案和理由说一下,All the ____worked hard to prepare for the evening party.空格中要填的适当单词是perform_百度作业帮
