Polyester and polyamide would be two synthetic polymers, created by condensation reaction.
The six steps of the scientific are:
1. State the question
2. Conduct research
3. Create a hypothesis
4. Perform the experiment
5. Analyze the data
6. Conclusion
So D. would be the correct answer, even though communicating the results could possibly be a step if it's required.
Answer:
a) rate law1 = k[NO2]²
b) rate law2 = k[NO][O3]
Explanation:
NO2(g) + CO(g) → NO(g) + CO2(g)
NO(g) + O3(g) → NO2(g) + O2(g)
When [NO2] in reaction 1 is doubled, the reaction quadruples
Rxn is second order.
rate law1= [NO2]^a [CO]^b
rate law1= [NO2]² [CO]^0
rate law1 = k[NO2]²
When [NO] in reaction 2 is doubled, the rate doubles.
Rxn is first order
The ratio is 1:1
this makes the rate law2 = k[NO][O3]
The number of Fe atoms within a single FeCl2 molecule are one.
Explanation:
Metallic iron produces only ferrous chloride (FeCl2) on treatment with hydrochloric acid. Hydrogen gas is also liberated as the other product. But when iron is heated with chlorine gas, ferric chloride (FeCl3) is formed.
Total number of atoms within a single FeCl2 molecule are 3 atoms.
The number of Fe atoms in FeCl2 molecule are one.
Number of Cl atoms in FeCl2 molecule are two.
Answer:
The covalent bonds within a single water molecule are called hydrogen bonds.
Explanation:
Covalent bonds are the bonds between the atoms within the same water molecule. Hydrogen bonds are the bonds between two water molecules. All molecules have covalent bonds, but only some molecules have hydrogen bonds.
