Answer:
Explanation:
Given that ;
Compound H is optically active and have a molecular formula of C6H10 and therefore undergo catalytic hydrogenation. Catalytic hydrogenation involves the use Platinum/Nickel to produce C6H12
i.e

The proposed H and I structures are shown in the diagrams attached below .
compound H represents 3- methyl cyclopentene
compound I represents methyl cyclopentane
However; 3- methyl cyclopentene posses just only one chiral carbon which is optically active at the third position and it R and S enantiomers are shown in the second diagram below.
Answer:
A. to absorb carbon dioxide from the atmosphere and use it to make sugar
Explanation:
Green plants with the help of their green coloring pigment called chlorophyll helps to absorb sunlight. This sunlight helps in the process Called photosynthesis in which plants manufacture food (sugar) using CO2(Carbon dioxide)and Water to give Oxygen and Sugar. The oxygen is released back into the atmosphere.
Answer:
the formula of its oxide is X2O3.
Answer:
2,400,000 torr (3 s.f.)
Explanation:
Convert the pressure from Pascal to atm first:

3.20 ×10⁸ Pa
= [(3.20 ×10⁸) ÷101325] atm
= 3158.2 atm (5 s.f.)
Convert atm to torr:

3158.2 atm
= (3158.2 ×760) torr
= 2400000 torr (3 s.f.)
Answer:
They can both be used in an electric circuit.
Explanation:
Though conductors and insulators are very different from each other but still they have a similarity that "they can both be used in an electric circuit".
Conductors are the material that allows electricity to flow and insulators have high resistance and do not allow electricity to flow.
Both conductors and insulators are used in an electric circuit as conductor is used in wires, batteries and bulb to flow current while insulators are used in insulation of wire, switches, plugs and etc. Combination of them makes the circuit shock free.
Hence, the correct answer is "They can both be used in an electric circuit."
