The particals in a physical change alwayd stay the same, but for a chemical change that is the only time they will change. Not during a physical change
Answer :I think it’s c
Hope this helps!
Answer:
8.067 g/cm^3
Explanation:
Density = Mass/Volume
where mass = 121g and....
Volume = (35 - 20) = 15ml
where 1ml = 1cm^3
So Density = 121/15
;Density = 8.067 g/cm^3
Displacement reaction
Because Al goes to SO4 and
Cu goes from SO4 to Cu
This happens because Al is more reactive (higher up in the reactivity series) than Cu
The given formula is : <span>LiC2H3O2
Examining this formula, we will find that:
Li stands for "lithium", and
C2H3O2 stands for "acetate"
Therefore, the given formula is that of "lithium acetate".</span>
