Answer:
480 g of oxygen.
Explanation:
C3H8 + 5O2 ---> 3CO2 + 4H2O
Using the molar masses:
3*12 + 6*16 g of CO2 were formed from 10*16 g O2
132g g CO2 from 160 g O2
1g CO2 from (160/132) g O2
396 g from (160/132) * 396
= 480 g of oxygen.
When a metal reacts with a salt, it displaces the metal present in the salt only if the metal has higher relative reactivity.
in this case , the displacing metal is same as the metal present in salt. both (being same metal)have same relative reactivity. hence, no displacement . NO reaction.
