a person not moving at all (if right put brainiest) plz
Answer:
Explanation:
Li(s)+1/2 F₂(g)→LiF(s)
In this reaction one mole of product is formed from gaseous state of reactants . So this reaction will represent the reaction for which ΔH∘rxn equals to ΔH∘f .
In other reaction one mole is not produced if we balance the reaction. The reactant must be in gaseous state . ΔH∘f . represents heat of formation . ΔH∘rxn represents heat of reaction .
The ionic equation will be:
<span>Mg2+(aq) + 2OH-(aq) + 2H+(aq) + 2NO3-(aq) → Mg2+(aq) + 2NO3-(aq) + 2H2O(l)
</span>And the net ionic:
<span>2OH-(aq) + 2H+(aq) → 2H2O(l)
</span>a Balanced equation would be:
<span>Mg(OH)2(aq) + 2HNO3(aq) → Mg(NO3)2 (aq) + 2H2O(l)
</span>Now thsi si so because of the standard equation which is base plus acid=Salt plus water. We need to have in mindo that Mg(OH)2 is sparingly soluble in water and is aqueous mos of the times
An electron because that is the only part able to be lost or gained without nuclear action needed
Answer: Strong (b)
Explanation:
INFRARED ACTIVE BONDS
Not all covalent bonds display bands in the IR spectrum. Only polar bonds do so. These are referred to as IR active.
The intensity of the bands depends on the magnitude of the dipole moment associated with the bond in question:
Strongly polar bonds such as carbonyl groups (C=0) produce strong bands.
