.8 grams of phosphorus are recommended.
Molecule C requires the least energy, Molecule B requires more, and Molecule A requires the most.
Explanation:
Molecule C is made up of a triple bond, which requires the most energy to break. Molecule B is made up of a double bond which is not as strong as a triple bond therefore requiring less energy. Molecule A is made up of a single bond which is the least strong thus requiring the least amount of energy.
Answer:
NH₃ and H⁺
Explanation:
The dissociation of NH₄Cl will lead to two ions , i.e. , NH⁴⁺ and Cl⁻ .
Hence , the reaction is -
NH₄Cl → NH⁴⁺ + Cl⁻
We can conclude that NH₄Cl can be formed from the ions , NH⁴⁺ and Cl⁻
Hence ,
According to the reaction ,
NH⁴⁺ + H₂O ⇆ NH₃ + H₃O⁺
Therefore ,
The reactant that will lead to the formation of NH₄Cl are - NH₃ and H⁺
Answer:
Friction
Explanation:
Friction is the force that opposes the tire rubber from sliding on the road surface.
