Displaced volume:
final volume - <span>initial volume
1 mL = 1 cm</span>³<span>
38.5 mL - 35.0 mL = 3.5 cm</span>³
hope this helps!
I believe the answer is E. uranium
Answer:
semipermeability
Explanation:
partially but not freely or wholly permeable specifically : permeable to some usually small molecules but not to other usually larger particles a semipermeable membrane.
Answer:
the molar mass is 40 and the metal is Calcium
Explanation:
X + H2SO4=X2SO4 + H2
The mole ratio is 1:1
no of mole of H2SO4= conc(M) × Vol(L)
=0.1×0.5
=0.05 mol
from the balanced chemical equation of the reaction
no of mole of 'X' = no of mole of H2SO4
thus no of mole of X=0.05 mol
Also, no of mole=mass/molar mass
molar mass of 'X'=mol/mass
=2/0.05
=40
