Answer: The question is is not complete...here is the complete question.
Which of the following reagents should be used to convert 3-Hexyne to E-3-hexene
Option B.
Na, liquid NH3.
Explanation:
3-Hexyne to E-3-hexene can be converted with by using the reagent of Na, NH3 (birch reduction) and this can be done by hdrogenation of H2.
The reagents NaNH3 convert 3-Hexyne to E-3-hexene because it is a reducing agents that convert or has the ability to reduce alkynes to trans alkenes.
3 Hexyne is an alkynes and it is converted to E- 3 hexene Na and NH3.
Answer:
700,000 holes
Explanation:
When heat energy occurs to produce free electrons, the number of free electrons produced is directly proportional and equal to the number of holes it produces at that time.
Hence, if silicon crystal (pure) has 700,000 free electrons, then the number of holes it have is also 700,000.
Answer:
C and A
Explanation:
i think it is because a solution is a mix of a solute and solvent, dont judge me if its wrong
de Broglie's wave equation describes that particles have wave properties. The equation is
λ = h/mv
Where λ is the wave length of the particle (m), h is the Planck's constant (6.62607 x 10⁻³⁴J s), m is the mass of a particle (kg) and v is the velocity (m/s).
λ = ?
h = 6.62607 x 10⁻³⁴ J s
m =200 g = 0.2 kg
v = 20 m/s
By substitution,
λ = 6.62607 x 10⁻³⁴ J s / (0.2 kg x 20 m/s)
λ = 1.66 x 10⁻³⁴ m
Hence, the wavelength of the 200 g ball 1.66 x 10⁻³⁴ m.
Hydrogen ions because acid dissociates into hydrogen ions when placed in aqueous solutions aka water
