Какой объем водорода необходим для получения железа массой 1,8 грамм из оксида железа

Ответы

Автор ответа: Keket

FeO+H2= Fe + H2O

1) n(Fe) = 1.8÷55.847 (молярная масса Fe) = 0.0322 моль
2) n(Fe) = n(H2) = 0.322 моль (т.к. коэффициенты в уравнении равны 1)
3) V(H2) = 0.322 моль × 22.4 = 7.2128 литра

Ответ: V(H2) = 7.2128 литра

Hi Paula,

How are you? I’m looking forward to your visit to New York next month.

We’re going to do lots of crazy things! First, I’m going to take you to Central Park. It’s a really big park in the middle of the city. We’re going to rent some bicycles and ride round. There’s a zoo, a boating lake, a museum of art and a place we can go ice skating – we are going to be really busy!

After the park, we’re going to have some food. Do you like pizza? Some friends are going to come over and meet us for lunch in a great pizza place on Times Square – that’s a really popular place with theatres and cinemas.
In the afternoon, we can walk up Fifth Avenue. This is the street with all the best shops.

And then we are going to go up the Empire State Building. It’s a very tall building (380 metres) and the views from the top are amazing. I hope you like heights!

I’m going to send you a link to some great websites so you can see everything. It’s really cold in December here so bring some warm clothes.

Have a safe journey,
Ben
