Because you’re body is using energy to keep you alive. Your breathing takes energy, so does your heart beat.
Answer:
The final volume of the sample of gas 
= 0.000151 
Explanation:
Initial volume 
= 200 ml = 0.0002
Initial temperature 
= 296 K
Initial pressure 
= 101.3 K pa
Final temperature 
= 336 K
Final pressure 
= K pa
Relation between P , V & T is given by
Put all the values in the above equation we get
= 0.000151
This is the final volume of the sample of gas.
Answer:
Option B. is correct
Explanation:
Wind turbines collect the kinetic energy of wind using the turbine blades. The blades turn an electric generator as they are connected to a drive shaft, which in turn produces electricity.
These turbine blades can disrupt flying wildlife including bats and birds.
So,
wind farms can disrupt migrating wildlife.
Option B. is correct.
The best set of reagents to achieve the ph-co2h => ph-come will be Br2, CH2N2.
A material or ingredient supplied to a system to trigger a chemical reaction or check to see whether one occurs is known as a reagent as well as an analytical reagent. Reactant refers to a substance that is consumed during a chemical reaction. The phrases reactant and reagent just aren't frequently used interchangeably.
Diazomethane reacts swiftly and extremely effectively, producing just N2 as a byproduct, making it an appealing methylating agent for carboxylic acids including phenols.
Therefore, the best set of reagents to achieve the ph-co2h => ph-come will be Br2, CH2N2.
