a) \(n_S=\frac{3,2}{32}=0,1\left(mol\right)\)

PTHH : \(S+O_2\underrightarrow{t^0}SO_2\)

PT :      1mol  1mol            1mol

Đề :      0,1mol  ?mol           ?mol

=>  \(n_{SO_2}=n_{O_2}=\frac{0,1\cdot1}{1}=0,1\left(mol\right)\)

=> \(m_{SO_2}=0,1\left(32+16\cdot2\right)=6,4\left(g\right)\)

b) \(V_{O_2}=0,1\cdot22,4=2,24\left(l\right)\)

a) 0.4g b)2.24g

There are many sports, which are good for our health and popular over the world. Soccer is one of my favorite sports. It is played by two teams consisting of 11 people each team. The general rule is that the ball is kicked by leg and the players get score when having the ball in their goal post. Football is known as “king” among other sports. First, it improves integrity when applying several techniques to create strong power. Second, it not only reduces stress and bad cholesterol of body but also relaxes out spirit after a hard working day. My brother usually plays football every afternoon after work as he is in a local sport club. Moreover, football is not simply one kind of sport, it is an art because of the popularity. Since there is an increasing number of football team over the world such as: Manchester United, Barcelona, Arsenal with professional players. Although I am not able to play well, I love watching football matches as they are interesting and we can also learn from their technique. Furthermore, football is public concern as well as heated debate. Football is now popular through women, who are thought not able to play this kind of sport.
