Question

(Please answer ASAP)

Write the expressions::

(i) Hydrochloric Acid + Zinc
(ii) Sulphuric acid + copper
(iii) Iron + Copper Sulphate
​

Answer 1

1) The reaction between zinc and HCl is given by the symbolic equation Zn + HCl→ ZnCl2 + H2.

2) Cu+H2SO4

3)Iron displaces copper ions from an aqueous solution of copper sulphate. It is a single displacement reaction of one metal by another metal. ... In this reaction, metallic iron is converted into ferrous ion (Fe2+) and cupric ion (Cu2 +) is converted into metallic copper. Fe (s) + Cu2 + (aq) —→ Fe2+ (aq) + Cu (s).

Answer 2

Answer:

Perform the TGA with your pure polymer. This analysis can give you the neat polymer degradation and the residue of polymer at the end of TGA analysis (say temperature > 500-600°C). If your polymer does not have any residue at the end (say >500°C) of your TGA experiment , the residue that you have, is originated from the filler
