Answer:
6 electrons
Explanation:
Nitrogen is a divalent gas (N2) in which each nitrogen atom contribute 3 electrons each, making a total of 6 electrons to form a triple bond between it's molecule(-N≡N-)
Answer:
1.
work out the mean mode median and range
Explanation:
Answer:
The weakest oxidizing agent is Zn^2+(aq)
The strongest reducing agent is Zn(s)
The strongest oxidizing agent is I2(s)
The weakest reducing agent is I^-(aq)
I^- cannot reduce Zn^2+ to Zn(s)
I2(s) can be reduced by hydrogen gas
Explanation:
In looking at oxidizing and reducing agents, our primary guide is the reduction potentials of each specie. The more negative the reduction potential of a specie, the better its function as a reducing agent. Zn has a very negative reduction potential hence it a very good reducing agent. Similarly, iodine has a very positive reduction potential hence it is a good oxidizing agent.
Only a specie having a more negative reduction potential than zinc can reduce it in aqueous solution. Similarly, the reaction potential of hydrogen is less than that of iodine hence hydrogen gas can reduce iodine.
Answer:
chlorine gas, sodium hydroxide, and hydrogen gas
Explanation:
The electrolysis of the sodium chloride NaCl solution (brine) will produce chlorine Cl₂ gas and solid sodium Na.
After that, because the reaction takes place in water solution, metallic sodium will react with water forming sodium hydroxide and hydrogen gas.
Na + H₂O → NaOH + H₂
Answer:
Greater the mass
Greater kinetic energy
Velocity
Greater kinetic energy
Mass and velocity
Explanation:
We know that kinetic energy of object
Where m=Mass of object
v=Velocity of object
Kinetic energy is directly proportional to mass and velocity of object.
When mass of object is greater then the object has greater kinetic energy when the mass of object is small then the object has small kinetic energy.
When the velocity of object is greater then the object has greater kinetic energy when the velocity of object is small then the object has small kinetic energy.
The greater the mass of an object moves,the greater the kinetic energy it has.
The greater the velocity of a moving object,the greater kinetic energy it has.
Kinetic energy depends on both mass and velocity of object.
