Answer:
Chlorine(Cl)
Explanation:
Because the shielding effect(by the inner electrons) remains the same but the nuclear charge is increasing(due to the increasing number of protons)
So Chlorine has the highest number of protons...so its outter electrons tend to expierence the most nuclear attraction hence making it more harder to remove the first electron
Answer:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O.
Explanation:
To balance the equation, you should apply the law of conservation of mass for the equations.
The law of conservation of mass states that the no. of each atom is equal in both sides (reactants and products).
Hydrocarbon is burned in oxygen to produce CO₂ and H₂O.
So, the given equation is balanced as:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O.
that 1.0 mole of C₃H₈ is burned in 5.0 moles of O₂ to produce 3.0 moles of CO₂ and 4.0 moles of H₂O.
The no. of all atoms is the same in both of reactants and products side.
C (3), O (10), and H (8).
Tempering is heat treatment technique that allows alloys to achieve toughness while aging is allowing alloys to diffuse and be dissolve it until microstructure shows.
