Answer:
4
Explanation:
The balanced equation for the reaction is as follows:
4Al + 3O2 --> 2(Al2O3)
Some are weaker than others it’s natural causes or they fight then d1e
Answer:
4 Fe + 6 02 ----> 2 Fe2O3
Explanation:
you need 4 iron and 6 oxygen in each side
Heat of vaporization of water = 540 cal/g
m=1000 g
energy supplied = 5.4 kcal=5400 cal
T1=T2=100 deg. C
so all energy is used to convert to steam
mass of steam produced = 5400 cal /(540 cal/g)
=5400/540 cal *g/cal
=10 g
