Answer:
unless it is acted upon a forcd
Periodic table is a scientific model
Answer is: c. MgSO₃.
In magnesium sulfite, magnesium has oxidation number +2, sulfur has oxidatidion number +4 and oxygen -2:
+2 + (+4) + 3·(-2) =0.
a) in calcium sulfide, calcium has oxidation number +2 and sulfur -2:
+2 + (-2) = 0.
b) in sodium nitride, sodium has oxidation number +1 and nitrogen -3:
3 · (+1) + (-3) = 0.
d) in aluminium nitrite, aluminium has oxidation number +3, nitrogen +3 and oxygen has -2:
+3 + (+3 + 2 · (-2)) · 3 = 0.
What it is made of?
A) Water and Salt- salt is solute, water is solvent
B) Water and Sugar- sugar is solute, water is solvent
C) Water and HCl- HCl is solute, water is solvent
D) Water and NaOH- NaOH is solute, water is solvent
Which of these substances would be a poor conductor of electricity?
Water and Sugar make a poor conductor because sugar does not ionize in water. The other 3 solutions have solutes that ionize and make good conductors.
