Answer:
24 moles
Explanation:
given data
= 48 grams
to find out
how many moles of 
will be produced
solution
we know that Stoichiometry is here as
......................1
so we get here mole of solute that is express as
mole = 
..........................2
put here value for
mole = 
mole of = 24 mole
and
we can say that here as per equation 1 that one mole of is go with one mole of
so here 24 mole is go with 24 moles mole of
so we can say will be produced 24 moles
A physical change. chemical changes require the molecule itself to change. If you put NaCl into solution, the NaCl is still there which is evident by the fact that if you lower the amount of water, NaCl precipitates out.
Answer:
Iron, or Fe, has 26 electrons, with two electrons in the outer valence shell. Iron is a transition metal and is both lustrous and easy to work with. Iron is also prone to rust, especially in damp environments. Iron is a ferrous metal, meaning that it can be magnetized.
Explanation:
I think the difference is the temperature because when something is melting the temperature is going up(increasing) or sometimes stayis the same and when something is freezing the temperature is going down(decreasing)
