Question

ma poate ajuta cineva va rog? dau coroana​

Answer 1

Răspuns:

Explicație:

H2O2=1/2 O2+H2O

1 mol H2O2....0.5 moli O2

X moli H2O2... 10 moli O2

X=10*1/0.5=20 moli

1 mol H2O2....34g

20 moli H2O2.......yg

Y=20*34/1=680g

C=md*100/ms

30=680*100/ms

Ms=2266,66g

Mai verifica tu calculele

B)1 mol O2....32g

10 moliO2...zg

Z=10*32=320g

2S+3O2->2SO3

2 moli S......3moli O2

a moli S.......10 moli O2

a=10*2/3=6.66 moli S

1 mol S.....32g

6.66 moli S...b g

b=32*6.66=213,33g
