Maggie Banes looked __26__at her watch—as she had done every few minutes for the last three hours. __27__ it was nearly eight o'clock. 'Where on earth is Jill?' she thought.'It isn't like her to be so late.’__28__,she picked up the plate of sandwiches she'd made for tea and went to the kitchen. __29__the door opened and Jill walked into the house. She looked tired. 'What a relief! Are you OK?' said Maggie loudly. 'Yes, I'm fine, Auntie,'replied Jill. 'I'm so sorry I'm late, but something strange happened on the way here.'__30__,Jill explained that, in her hurry to get through the woods, she had tripped and knocked herself unconscious. When she woke up, she realised she was lost. 'I walked around for ages until I found the right path. Then I ran alt the way here.
A. Reluctantly
B. Just then
C. anxiously
D. To her aunt’s amazement
E. She was dismayed to see that
Al3+在0.1mol·L-1HCl溶液中还原时,其极谱波的半波电位为-1.46V。在滴汞电极电位为-1.70V时,测得溶液的电流值如下:
溶液 | i/μA |
20.00mL 0.200mol·L-1HCl,稀释至40.00mL | 10.2 |
20.00mL 0.200mol·L-1HCl,加试样溶液10.00mL, 稀释至40.00mL | 33.3 |
20.00mL 0.200mol·L-1HCl,加试样溶液10.00mL, 再加入10.00mL 6.32×103+mol·L-1Al3+溶液 | 52.0 |
根据以上极谱分析数据,计算Al3+的质量浓度(以mg·L-1为单位,已知M(Al)=26.98g·mol-1。)。
S和Cl,Mg和Al都处在同一周期,故第一电离能I(Al)>I(Mg),I(Cl)>I(Mg)。 ( )
