1) CuO + CO = Cu + CO2

n(CuO) = 250/80 = 3,125 моль

n(Cu) = n(CuO) = 3,125 моль

m(Cu) = 3,125 * 64 = 200г

Birthday is a very wonderful day. Everybody likes to celebrate it. It is a good opportunity to spend time with friends, parents, relatives,

I was born on the 10th of January. In the morning on my birthday my parents lay the presents near my bed. So the first thing I see when I open my eyes is my presents. My Mam and Daddy and my little brother come to my room to congratulate me and to sing “Happy Birthday”.

Usually we hold my birthday party in the evening. Once we went to a cafe to celebrate my birthday, but usually we celebrate it at home

We clean the house the day before birthday. In the morning of birthday party day my father goes shopping and buyes everything we need. My mother bakes a cake or pie.

By the evening food is cooked, the table is layed. We put on evening suits and dresses and wait for the guests. The flat looks nice and cosy.

I am always very glad to meet my guests. I like to get flowers and presents. Mam gives me the telegram from my aunt from Russia. We have an abundant dinner on this day. Mam brings in the birthday cake. I blow the candles out.

We dance and sing songs, play games and laugh, joke, tell funny stories.

I think that my birthday is one of the best days in a year.
