Suppose you have a system made up of water only, with the container and everything beyond being the surroundings. Consider a pro
cess in which the water is first evaporated and then condensed back into its original container.
Is this two-step process necessarily reversible?
2 answers:
Answer:

Answer:
No
Explanation:
No, because there is no evidence that the surroundings are also restored to their original state.
cannot be undone by exactly reversing the change to the system; Spontaneous processes are irreversible.

The rate of growth is faster in the (10 - 14) age group and slows down after the age of 14. After the age of 16 the growth is the slowest
384000000m
to change from m to km you just need to divide that give unit in Meters by 1000
which equals,
384000
so,
384000000 meters = 384000 kilometers
20.7 g of Fe can be produced with 10.0g of Al
Answer:
80.6 g
Explanation:
MgO=24.3+16=40.3 g
48.6/24.3= 2 moles
64/2x16= 2 moles
2x40.3= 80.6g
