Автор ответа: Komsomolka

CaCO3 + 2HCl = CaCl2 + CO2 + H2O

n(CaCO3) = m/M = 300/100 = 3 моль

n(CO2) = n(CaCO3) = 3 моль

тогда V(CO2) = n*Vm = 3* 22,4= 67,2 л

1. For Indira and her classmates, the journey to school just got a lot hander. The Indonesian schoolgirl lives on one side of the Ciberang River but her school is on the other side — and the river has been flooding.
On Monday, the rising waters broke a pillar supporting a suspension bridge that the children usually use. There is another bridge, but it is too far away and the kids don't want to be late for school. Indiana Jones himself would find it too risky, but children don't seem to worry — the most important thing for them is to be at school on time!
2. Every morning before dawn, more than 50 children from Xinmin village in China get up at 5 a.m. and head for school eight kilometers away. To get to school they have to cross three mountains. As they start very early and it is still dark they take flashlights with them. There are some dangerous parts of the road, and when the children come to these, the younger ones have to hold onto the older children's hands. Two hours later, they arrive at school and begin their day.
3. Going to school in China is no joke. Nearly 500 children from one of the village cross the most dangerous part of the Nujiang River every day. There is no bridge over the river. Instead there is a steel cable over it. The children fasten themselves to the cable with a metal carabiner and a rope and slide across the 200-metre-wide canyon.
Mei, 5 years old, who was once stuck in the middle of the cable for nearly 20 minutes, told reporters, 'I used to dream of having a bridge, but then I learned that my dream was too expensive.'
However, officials have finally agreed to spend 35,000 on a bridge after a TV programme was made about the children's dangerous daily journey.
