Asteroids come from the asteroid belt
Answer:
im not too smart, but i would say, either b or d
Explanation:
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
Answer:
1.40M = [N2O4]
Explanation:
Based on the reaction:
2NO2(g) ⇄ N2O4(g)
Kc is defined as:
Kc = 5.0 = [N2O4] / [NO2]²
<em>Where [] are the concentrations in equilibrium of each gas</em>
As the equilibrium concentration of NO2 is 0.53M:
5.0 = [N2O4] / [0.53]²
5.0 = [N2O4] / [0.2809]
5.0*0.2809 = [N2O4]
<h3>1.40M = [N2O4]</h3><h3 />
