№1. Online services are replacing traditional ones, although the process is taking longer than it (1) to do. These days we can shop, contact friends, organize our holidays and even get rid of an old sofa without (2) our living rooms.
Most of our business and communication nowadays is (3) online, but what we (4) not realize is that there's a downside to this trend. For instance, hundreds of post offices around Britain (5) closed, and it seems that traditional shopping malls might (6) as well due to the increase in online shopping.
However, online shopping isn't without its problems. For instance, its impossible to try on (7) item of clothing online, and sizes vary so much from brand to brand that you never know quite what you (8). Some online shops often provide misleading infommation about their products to attract (9) customers. We would like to believe what the sellers tell us, but we may need to do more research before buying a product. In other words, convenience comes at a price, but it seems it's a price (10) we are willing to pay.

№2. Social networking has changed the way we communicate with each other. We can now connect with people (1) over the world in an instant. But is it as good as so many people seem to think it is?
Personally speaking, I've got nothing (2) social networking sites if people use them responsibly.
However, when people share too much information about themselves, you may end up with serious privacy (3).
This is especially true for younger users, (4) pre-teens, who may reveal more than they should. They may often do this (5) realizing that everyone can see what they've posted online - not just their friends.
Then, there's the whole question of cyber bulying - where people use the sites to spread damaging (6) about someone. That (7) of behaviour is completely unacceptable. Something should really be (8) about this. I know that sites (9) you to block someone who behaves inappropriately, but is this enough? If I was a parent, I would do whatever it took
to ensure my child's online (10).

Из перечня формул выпишите отдельно формулы нормальных, кислых и основных солей, дайте им названия: BaOHBr, Al2(SO4)3, Mn(HSO4)2, Pb(NO3)2 , (ZnOH)2SO4, KHSO3 , CaHPO4 , (SrOH)2S
Задание 2. Зная химические свойства основных классов соединений неорганической химии (оксидов, оснований, кислот и солей), запишите уравнения реакций пяти возможных способов получения хлорида железа (II).
Задание 3. Закончите молекулярные уравнения возможных реакций, протекающих в растворах, запишите одну реакцию в ионном виде на ваше усмотрение. Если реакция не может быть осуществлена, объясните почему. (Подсказка: зная к какому классу веществ относится реагируемое вещество, нужно вспомнить его свойства, т.е. с какими веществами оно реагирует. Если в перечне веществ нет данного класса соединений, то скорей всего реакция невозможна).
а) гидроксид лития + бромид алюминия →
б) бромид железа (III) + нитрат серебра →
в) алюминий + хлорид железа (II) →
г) сульфат магния + азотистая кислота →
д) гидроксид кальция + хлорид лития →
е) железо + сульфат магния →
ж) бромид цинка + сульфат никеля →
з) силикат натрия + азотная кислота →
