Separate this redox reaction into its component half-reactions. 3o2 4co
swat32
The equation is:
3 O₂ + 4 Co → 2 Co₂O₃
Oxidation half reaction:
Co → Co³⁺ + 3 e
Reduction half reaction:
O₂ + 4 e → 2 O²⁻
To balance the equation number of electrons lost must be equal to number or electrons gained so we must multiply oxidation half time 4 and reduction half times 3

Why ozone is important to organic chemistry​
Nikolay [14]

Answer:

Ozone is good in the stratosphere because it absorbs all of the most energetic ultraviolet radiation (UV-C), most of the UV-B radiation and some of the least energetic UV radiation (UV-A). Ozone is “bad” in the troposphere because it is harmful to breathe and is the primary component of smog in summer.

Density=mass/volume. Put the mass (2790g) over the volume (205mL)

Density= 2790g/205mL
Your answer should be in g/mL.
Hope this helped! :)

NEED ANSWER FAST
Korolek [52]

Answer: Option (c) is the correct answer.

Explanation:

When current passes through a wire then a magnetic field is formed. Therefore, when two wires carry current in the same direction then both the wires with have respective magnetic fields in the same direction and their total magnetic field will be large.

But when current between two wires flow in opposite direction then the magnetic field produced will also be in opposite direction. Therefore, both the magnetic fields cancel each other out. Thus, total magnetic field will be small.

As a result, wires which carry current in the opposite direction repel each other.
