Відповідь:

NaHCO3 (бикарбонат натрия) + тепловое воздействие -> Na2CO3 (карбонат натрия) + CO2 (диоксид углерода) + H2O (вода)

Na2CO3 + BaCl2 (хлорид бария) -> BaCO3 (карбонат бария) + 2NaCl (хлорид натрия)

BaCO3 -> BaO (оксид бария) + CO2

Таким образом, начиная с бикарбоната натрия, мы можем получить карбонат натрия, карбонат бария и диоксид углерода, а затем превратить карбонат бария в оксид бария и диоксид углерода.

TRAFFIC IN BRITAIN.
Traffic in Britain is getting heavier all the time and the roads of most big cities are
almost permanently blocked by a slow moving procession of metal cages. One-way
streets and traffic lights have not settled the problem. The motorist driving in
crowded towns gets very little pleasure of it.
Some time ago , a friend of mine who works in a part of the city I don’t know very
well, invited me to call on him, It took me hours to get there and I drove round and
looking for a place to park my car. At last I parked it in a backstreet. As I was
already three quarters of an hour late I hurried off on foot. Walking quickly along the
street I couldn’t help thinking that it’s much easier to walk than to drive.
At noon , just as I was leaving my friend’s office, it suddenly struck me that I had no
idea where I had parked my car. I’d hardly go up to a policeman and tell him that I
had lost a small green car somewhere ! I ‘d simply have to look for it myself.
Walking down street after street. I looked over each car closely and was happy to
see a small green car just behind an old cart. But how disappointed I was to discover
that though the car was exactly like my own, it belonged to someone else! Feeling
quite tired now, I decided to drop the search for a while and went off for lunch.
Some time later, I left the restaurant and was walking down the street. Turning the
corner I nearly jumped for joy: my car was right in front of me –and there was no
mistake this time. I couldn’t help smiling as I approached it. Stuck on the windscreen
was a little ticket which informed me that the car had been visited by a policeman in
my absence. On top off all, I had broken the traffic regulations !
