Answer:
Correct option: Vapor pressure increases with temperature
Explanation:
Vopor pressure: it is defined as the pressure exerted by gaseous molecule on the surface of container and vopor is produced by only volatile component of solution.
Kinetic energy of molecule depends on the temperaure of sample or molecules when temperature is increased then its kinetic energy also increased and as kinetic energy increases then the chances of molecule going into vapour phase increases thereby increasing the vapour pressure.
hence Vapor pressure increases with temperature
Answer:
403.3 kPa is the new pressure
Explanation:
This problem is solved by this formula:
P₁ . V₁ = P₂ . V₂
101kPa . 575 mL = P₂ . 144mL
(101kPa . 575 mL) / 144 mL = P₂
403.3 kPa = P₂
Answer:
Chemical energy
Explanation:
Energy in carbohydrates is stored as chemical energy which is released when the carbohydrate is broken down by the body to give glucose and ATP. Animals eat carbohydrates as energy molecules from which they derive energy from the stored chemical energy.
Answer:
Usually light years, or parsecs.
Explanation:
Answer:
1) acetylide
2) enol
3) aldehydes
4) tautomers
5) alkynes
6) Hydroboration
7) Keto
8) methyl ketones
Explanation:
Acetylide anions (R-C≡C^-) is a strong nucleophile. Being a strong nucleophile, we can use it to open up an epoxide ring by SN2 mechanism. The attack of the acetylide ion occurs from the backside of the epoxide ring. It must attack at the less substituted side of the epoxide.
Oxomercuration of alkynes and hydroboration of alkynes are similar reactions in that they both yield carbonyl compounds that often exhibit keto-enol tautomerism.
The equilibrium position may lie towards the Keto form of the compound. Usually, if terminal alkynes are used, the product of the reaction is a methyl ketone.
