By the Balanced eqn
60g ethane requires 7x32= 224g oxygen
here ethane is in excess.oxygen will be fully consumed
hence
300g oxygen will consume
60
⋅
300
224
=
80.36
g
ethane
leaving (270-80.36)= 189.64 g ethane.
By the Balanced eqn
60g ethane produces 4x44 g CO2
hence amount of CO2 produced =
4
⋅
44
⋅
80.36
60
=

g
and its no. of moles will be
235.72
44
=5.36 where 44 is the molar mass of Carbon dioxide

<span>C. Gravity acts on all objects in the universe.
think about Newtons Laws of Motion</span>
Resources that come from nature, some examples include: Water, Gold, Oil, Coal, Apples, Oranges, etc.
Because the physical appearance change hope this helps

Single replacement reactions. For example copper is more reactive than silver. So a copper wire in a silver solution will cause the silver to become a metal again.
