Answer:
b/c the line of electronegativity pass through germanium
Answer : The concentration of nitrate ions is 0.450 m.
Solution : Given,
Molarity of = 0.225 m
The balanced ionic equation is,
From the reaction, we conclude that the 1 mole of produces 2 moles of ions. That means the concentration of nitrate ions is twice the value of .
then, 0.225 m of gives 2 × 0.225 of ions
Now the concentration of ions is equal to 0.450 m.
The state of the compounds are:
Na₂co₃- basic salt
NaHC₂O₄- acidic
FeCl₃- acidic
NH₄br- acidic
KClO₄- neutral
<h3>What is the state of the compound?</h3>
The state of the compound is its acidity, basicity, and neutrality. The compounds are the mixture of opposite elements.
Thus, the state of the compounds are:
Na₂co₃- basic salt
NaHC₂O₄- acidic
