2Fe2O3=4Fe+3O2
1 mole Fe2O3=56*2+3*16=160g
2*160g Fe2O3.....4*56gFe.....6*16g O
11gFe2O3....x g Fe....y g O
x=11*4*56/(2*160)=7.7 g Fe
y=11*6*16/(2*160)=3.3g O

If 56 grams of notrogen are used up by the reaction, how many grams of amonia will be produced? 1N2+3H2--> 2NH3
djverab [1.8K]
1 mole of N2 produces 2 moles of NH3
OR...
14 x 2 grams of N2 produces 2(14 +3) grams of NH3
1 gram of N2 produces 34/28 grams of NH3
therefore, 56 grams produce (34/28 )x 56 =68 grams of NH3 

the answer thus would be 68 grams of NH3

How can you make clay float in water?​
erastovalidia [21]
To make clay float in water you have to shape it into something wide enough and roughly bowl-shaped so that it can displace enough water to compensate for its mass, just like a real boat.
