Answer: Laws have been passed banning the production of a living copy of a person.
i just took the test so i know the answer is correct.
Answer:
A. Methanol
B. 2-chloropropan-1-ol
C. 2,2-dichloroethanol
D. 2,2-difluoropropan-1-ol
Explanation:
Primary alcohols are stronger acids than secondary alcohols which are stronger than tertiary alcohols.
This trend is so because of the stability of the alkoxide ion formed(stabilising the base, increases the acidity). A more stabilised alkoxide ion is a weaker conjugate base (dissociation of an acid in water).
By electronic factors, When there are alkyl groups donating electrons, the density of electrons on th O- will increase a d thereby make it less stable.
By stearic factors, More alkyl group bonded to the -OH would mean the bulkier the alkoxide ion which would be harder to stabilise.
Down the group of the periodic table, basicity (metallic character) decreases as we go from F– to Cl– to Br– to I– because that negative charge is being spread out over a larger volume that is electronegativity decreases down the group.
Electronegative atoms give rise to inductive effect and a decrease in indutive effects leads to a decrease in acidity. Therefore an Increasing distance from the -OH group lsads to a decrease in acidity.
From above,
A. Methanol
B. 2-chloropropan-1-ol
C. 2,2-dichloroethanol
D. 2,2-difluoropropan-1-ol

Answer:
The answer to your question is: first option.
Explanation:
C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + energy. This option is correct, 1 molecule of glucose reacts with 6 molecules of oxygen and produces 6 molecules of carbon dioxide, six molecules of water and energy.
C5H12O6 + 6 O2 → 5 CO2 + 6 H2O + energy. This option is incorrect because glucose has 6 carbons not five.
5 CO2 + 6 H2O → C5H12O6 + 6 O2 + energy. This is the reaction of photosynthesis, it is the inverse reaction of cellular respiration.
C6H12O6 + energy → 6 CO2+ 6 H2O + 6 O2. This reaction does not exist.
Answer: metal
Explanation: it says element so conductor and semiconductor are out and a halogen is a group of gases on the periodic table so this brings up to a conclusion of metal.
