Answer:
A.
Explanation:
While solar power does produce carbon dioxide emissions in the manufacturing processes required to produce panels and batteries, it does not produce CO2 while converting solar energy to electrical energy.
1.Electrons can be transferred from one atom to another.
2.Electrons can be shared between neighbouring atoms.
3.Electrons can be shared with all atoms in a material.
The answer is the 3rd one
Polyester is a condensation polymer of dicarboxylic acid and diol.
Example : Polethylene terphthalate is polymer of ethylene glycol and tere phthallic acid.
When a strong acid like HCl or a strong base like NaOH comes in contact with polyester (like spilled on slacks) it causes hydrolysis of polyester and it get converted back to dicarboxylic and diol(the monomers).
the general reaction will be
RCOOR' ---> RCOOH + R'OH
Thus slacks will get teared.
