Oxygen cannot be broken down into a simpler substance by using chemicals :) Hope this helps and the other answer gets removed :)
Answer is: the % ionization of hypochlorous acid is 0.14.
Balanced chemical
reaction (dissociation) of an aqueous solution of hypochlorous acid:
HClO(aq) ⇄ H⁺(aq) + ClO⁻(aq).
Ka = [H⁺] · [ClO⁻] / [HClO].
[H⁺] is equilibrium concentration of hydrogen cations or protons.
[ClO⁻] is equilibrium concentration of hypochlorite anions.
[HClO]
is equilibrium concentration of hypochlorous acid.
Ka is the acid
dissociation constant.
Ka(HClO) = 3.0·10⁻⁸.
c(HClO) = 0.015 M.
Ka(HClO) = α² · c(HClO).
α = √(3.0·10⁻⁸ ÷ 0.015).
α = 0.0014 · 100% = 0.14%.
Answer:
A) 6.15×10^14 per sec
B)2.5 sec
Explanation:
Wavelength of light = 488 nm
speed of light = 3×10^8 m/s
therefore, frequency of light 
⇒ 
⇒ν= 6.15×10^14 per sec
b) distance between moon and earth = 3.8×10^5 km.
= 3.8×10^8 m
light travel from earth moon and back to earth
therefore, distance traveled= 2× 3.8×10^8 m = 7.6×10^8 m
therefore time= distance/speed
⇒ time= 
= 2.5 sec
So, for a round trip time required is 2.5 sec.
Answer:
Increased use of resources
Additional waste produced
More construction
Cutting down trees
The question is incomplete, the complete question is;
When a lead acid car battery is recharged by the alternator, it acts essentially as an electrolytic cell in which solid lead(II) sulfate PbSO₄ is reduced to lead at the cathode and oxidized to solid lead(II) oxide PbO at the anode.
Suppose a current of 96.0 A is fed into a car battery for 37.0 seconds. Calculate the mass of lead deposited on the cathode of the battery. Round your answer to 3 significant digits. Also, be sure your answer contains a unit symbol.
Answer:
3.81 g of lead
Explanation:
The equation of the reaction is;
Pb^2+(aq) + 2e ---->Pb(s)
Quantity of charge = 96.0 A * 37.0 seconds = 3552 C
Now we have that 1F = 96500 C so;
207 g of lead is deposited by 2 * 96500 C
x g of lead is deposited by 3552 C
x = 207 * 3552/2 * 96500
x = 735264/193000
x = 3.81 g of lead
