____________

V(H2)-?

H2+CoO=Co+H2O

M(CoO)=59g/mol+16g/mol=75g/mol

M(H2)=2g/mol

m(H2)=2g*25g/75g=0.6g

n(H2)=0.6g/2g/mol=0.3mol

V(H2)=0.3ml*22.4l/mol=6.72l

MY HOBBIES / INTERESTS

I also like both computer games and board games. We have one computer at home but sometimes Dad brings home his laptop and we can play a network game.

My favorite computer games are strategy, sport and adventure games. I got my first

computer two or three years ago and my first game was FIFA 2003. This is a game where you play different football teams. It was great. My favorite adventure game is Broken Sword III. As for strategy games, I like Command Conquer best.

When I’m outside with my friends we also play certain games. Not the silly games for little children, like hide-and-seek or piggy-in-the middle, but more serious things. We play pirates, who fight with each other to get the treasure or the Lord of Ring – I like to be Aragon best. And of course there is nothing better than good game of football played with your friends!
