Answer:
opposite
Explanation:
Newtons law explains that for every action force there is an equal and opposite reaction.
Answer:
1. Diazonium salt
2. Coupling component
Explanation:
Azo dyes re synthesized by the combination of two organic compounds viz
1. Diazonium salt
2. Coupling component
1) For methyl red, the diazonium salt which is an intermediate product is produced by the reaction of hydrochloric acid (HCL) with anthranilic acid and sodium nitrate (NaNO₂)
2) The produced diazonium salt is then combined with dimethylaniline which is a coupling component rich in electrons to undergo a chemical reaction that by an aromatic substitution mechanism to produce methyl red as the final product.
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
