I would say 2 because co2 goes out and o goes in
Answer:
A
Explanation:
Simply put, one of these is not like the others. The only one involved with changing instead of reshaping is the egg.
There are two kinds of polymers : addition polymers and condensation polymers
In case of addition polymers, there is simple addition of unsaturated monomeric units. example: polythene
While in case of condensation polymers, the monomers combine with the elimination of a small molecule like H2O, HCl, NH3 etc.
So here as there is formation of H2O as product there is formation of a polymer and that too a condensation polymer
Example: condensation polymer of diamine and dicarboxylic acid to form a polyamide (Nylon-6,6)
Answer: condensation
formation of polymer
I think “A” is the right answer
Answer: 49.0 cm^3
Explanation:
1) formula: density = mass / volume
=> volume = mass / density
2) mass (given) = 54.6 g
3) density (given) = 1114 kg / m^3
conversion of units: 1114 kg/ m^3 * 1000 g/kg * 1 m^3 / (1,000,000 cm^3) = 1.114 g/cm^3
4) calculation:
volume = 54.6 g / 1.114 g/cm^3 = 49.0 cm^3
