26 C because co needs one more oxygen!!

plxxx tell me know me the conditions for hydrogenation,hydration(alcohol formation),cracking, acid making and esterification??i mean the temperature, pressure,catalysts??????????????????pleaseeeeeeeeeeeeeee

what is difference b\w condensation and addition polymers?

in condensation a simple molecule is also formed as by product like H2O

in additon only one product forms

what is difference b\w condensation and addition polymers?

In addition polymer 2 same monomer units join together to form polymer only and nothing additional is formed like C2H4 will form polyethene.
in condensation 2 different monomers join and they form the polymer and a water molecule, like polyesters and polyamides.

what is difference b\w condensation and addition polymers?

condensation polymer releases H2O molecule on production
addition polymer does not produce any byproduct

how?

bcuz ammonium has covalent bond and btween cloride has ionic bond !!!

lol so many people answer so fast

what is difference b\w condensation and addition polymers?

Addition polymerisation: In which unsaturated monomers are linked to form a polymer(polyethene)
Condensation: In which SATURATED monomers r linked to form a polymer(protein,terylene etc.)

hahaha..... no g i was typing wen got the NEW ALERT on my page ... that's wen u posted so ...oh ok u were first!

no its not aboubt the first one who posts its about the quality of your post !!!

hydrogenation needs 180c and nickel
hydration needs 300c and phosphoric acid
cracking needs al203 and high temperature(different temp for different products) or porcelean chips or ceramics...
acid making needs alcohol and potassium dichromate or any other oxidizing agent.
esterification needs conc h2s04

The mass of one mole of a chloride formed by a metal Y is 74.5 g.​

What is the formula of the chloride?​

A Y3Cl B Y2Cl C YCl D YCl 2​

C its potassium chloride becasue since one mole has mass in decimals it means there is only 1 atom of Cl which is 35.5 u subtract that ... 74.5- 35.5 = 39 which is Potassium which has valency of +1
