Answer:
Getting knowledge from the outside world with our senses, and scientific tools.
Explanation:
(e.g. a doctor watched a patient after giving them a. vaccine)
Electronegativity is determined by factors like the nuclear charge
Explanation:
here's the answer to your question
Condensation polymerization : releasing water as by product, occurs in monomer that has functional group that can react with each other e.g alcohol&carboxlic acid to form polyesters, carboxylic acid and amines to form polyamides,etc.
Radical Polymerization: occurs by propagating radical monomers or monomer that has unsaturated bonds, such as ethene, initiated by formation of radical from the monomer by using uv lights/other initiator, does not produce any by products
Mass of Hydrogen gas required to react : 0.936 g
<h3>Further explanation</h3>
Reaction on Nitrogen gas and Hydrogen gas to produce Ammonia gas
N₂ (g) + 3 H₂ (g) ⇒ 2 NH₃ (g)
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol
so mol Nitrogen for 3.5 L at STP :
From the equation, mol ratio of N₂ : H₂ = 1 : 3, so mol H₂ :
then mass of Hydrogen(MW= 2 g/mol) :
