When Mary Moore began her high school in 1951, her mother told her, “Be sure and take a typing course so when this show business thing doesn’t work out, you’ll have something to rely on.” Mary responded in typical teenage fashion. From that moment on, “the very last thing I ever thought about doing was taking a typing course,” she recalls.

The show business thing worked out, of course. In her career, Mary won many awards. Only recently, when she began to write Growing Up Again, did she regret ignoring her mom. “I don’t know how to use a computer,” she admits.

Unlike her 1995 autobiography, After All, her second book is less about life as an　award-winning actress and more about living with diabetes (糖尿病). All the money from the book is intended for the Juvenile Diabetes Research Foundation (JDRF), an organization she serves as international chairman. “I felt there was a need for a book like this,” she says. “I didn’t want to lecture, but I wanted other diabetics to know that things get better when we’re self-controlled and do our part in managing the disease.”

But she hasn’t always practiced what she teaches. In her book, she describes that awful day, almost 40 years ago, when she received two pieces of life-changing news. First, she had lost the baby she was carrying, and second, tests showed that she had diabetes. In a childlike act, she left the hospital and treated herself to a box of doughnuts (甜甜圈). Years would pass before she realized she had to grow up－again－and take control of her diabetes, not let it control her. Only then did she kick her three-pack-a-day cigarette habit, overcome her addiction to alcohol, and begin to follow a balanced diet.

Although her disease has affected her eyesight and forced her to the sidelines of the dance floor, she refuses to fall into self-pity. “Everybody on earth can ask, ‘why me?’ about something or other,” she insists. “It doesn’t do any good. No one is immune (免疫的) to heartache, pain, and disappointments. Sometimes we can make things better by helping others. I’ve come to realize the importance of that as I’ve grown up this second time. I want to speak out and be as helpful as I can be.”

你能只用一种试剂就可以把CuSO₄、NaOH、NH₄NO₃、NaCl、CaCO₃五种白色固体----鉴别出来吗？请讲述实验过程、实验现象及结论．

甲公司和乙公司双方签订买卖合同，甲公司向乙公司购入价值100万元的货物用于试制新产品，承诺3个月后付款，双方未对所有权的转移作出其他约定。甲公司应乙公司的要求，请A公司和B公司作担保人。其中，A公司以自有的一套加工设备提供抵押担保，B公司提供保证担保。
乙公司向甲公司按期供货后，甲公司为筹集资金，将购入的该批货物作为抵押物，向银行贷款50万元，并办理了抵押登记手续。几天后，甲公司又将已经用于抵押的一部分货物以30万元的价款转让给丙公司。该转让合同签订时甲公司没有经银行同意。
由于试制新产品失败，甲公司在承诺的付款期满后，未能向乙公司支付所欠的货款。乙公司要求B公司代为偿还。B公司认为合同中未注明保证的方式，属于一般保证。在乙公司就甲公司财产依法强制执行用于清偿债务前，自己享有先诉抗辩权，拒绝承担保证责任，另外，B公司还认为自己提供的是保证担保，乙公司应当先就A公司物的担保实现债权。
乙还调查了解到甲公司的以下情况：
(1)甲公司是由C、D、E三位股东共同出资设立的有限责任公司，三位股东各持有1/3的股份。该公司没有设立董事会，由C股东担任执行董事兼监事，D股东担任总经理兼公司法定代表人。
(2)对甲公司将其用于抵押的设备在抵押期内又转让的作法，E股东认为不合法。E股东曾提议召开临时股东会讨论解聘C的职务，但由于C股东和D股东拒绝未能召开。
(3)D股东曾私自将公司的部分资产为其亲友贷款作抵押，给甲公司造成损失10万元。
问题：

甲公司将购入后尚未付款的货物用于抵押担保是否合法说明理由。
