4P + 5O2 = 2P2O5
Al2(SO4)3 = Al2O3 + 3SO3
SiO2 + 2KOH = K2SiO3 + H2O
2Cr(OH)3 = Cr2O3 + 3H2O
N2O5 + H2O = 2HNO3

Task 2. Read the article again and decide if the statements are true (T) or false (F). An extra in a movie is an actor who doesn't speak. We see these actors in the background of a movie scene. Many movies have hundreds of extras. This is especially true for action movies that have got scenes where many people are running from some dangerous event. But if an actor has just got one speaking part in a movie, they aren't an extra any more, What are they exactly then? They're not main actors, of course, you probably won't see their name at the start of the movie although sometimes they completely change the story in the movie. Their roles can be very Important, even if they only say one single line. This kind of role is called a 'bit part'. A'bit 'is something really small. This is why we use this word to describe these very small parts.an actor who does these kinds of roles all the time is called a 'bit player'. Maybe you've seen an actor like this in more than one movie. You don't know who she or he is exactly but you think, hmm, where have I seen this actor before? There are a lot of actors who do bit parts as a hobby. They live near Hollywood and they've probably got other jobs, They also make good money doing bit parts. However, most actors do bit parts because they want bigger roles. This is true for most of today's famous actors. Sometimes, though, actors who do bit parts never get to do more than that. Still, it can be a really fun job. A famous acting teacher once said, There are no small parts, only small actors. ' So if someone offers you a bit part, play the role like it's the role of a lifetime! вопрос : A bit part always changes the story of a movie. F T
