MgCl₂(aq) + 2LiOH(aq) = Mg(OH)₂(s) + 2LiCl(aq)
Mg²⁺ + 2Cl⁻ + 2Li⁺ + 2OH⁻ = Mg(OH)₂ + 2Li⁺ + 2Cl⁻
Mg²⁺ + 2OH⁻ = Mg(OH)₂ <span>the net ionic equation</span>
Answer:
Sound needs a medium through which to travel.
Explanation:
In space there is no air or medium. Sound waves need medium to travel. It cannot travel through vacuum. Sounds waves are mechanical waves unlike electromagnetic waves. Electromagnetic waves can travel through vacuum. But mechanical waves such as sound waves needs a medium to propagate the energy. So it is very unlikely that people inside the space station can hear the explosion that occurs in space outside the space station.
Balance Fe
Fe3O4 + H2→ 3Fe + H2O
Balance O
Fe3O4 + H2→ 3Fe + 4H2O
Balance H
Fe3O4 + 4H2→ 3Fe+4H2O
Coeff of H2O=4
Answer:
20%
Explanation:
mass by mass percentage of a solution =(mass of solute)/(mass of solution)
mass of solute=550g
therefore 110×100/550=20%
