Explanation:
Answer:
1.21 × 10⁻³⁰ m
Explanation:
1 mol of photons causing the change in the conformation of 11-retinal has an energy of 164 kJ. We can find out the wavelength (λ) associated with this energy (E) using the Planck-Einstein equation.
E = h . c . λ⁻¹
where,
h is the Planck's constant
c is the speed of light
λ = h . c . E⁻¹ = (6.63 × 10⁻³⁴ J × s) × (3.00 × 10⁸ m/s) × (164 × 10³ J)⁻¹ = 1.21 × 10⁻³⁰ m
Answer:
Explanation:
All you need to know is the atomic mass of platinum, and Avogadro's number.
2.00g Pt divided by atomic mass gives you the moles of platinum, and multiplying by avogadro's number (6.022 x 10^23) gives you the number of atoms.
Atomic mass of platinum can be found on any periodic table.
Hope this helped.
<h3>Answer:</h3>
C₆H₁₄ is the only Alkane in given compounds.
<h3>Explanation:</h3>
The General Formula for Alkanes is as follow;
Cₓ H₂ₓ ₊ ₂
where;
x = whole number
It means in alkanes for every x number of carbon atoms we have 2x + 2 number of hydrogen atoms. Let's apply this formula on given compounds.
CH₂O:
As there is one carbon atom in this compound hence, the number of hydrogen atoms present for one carbon atom in alkane must be equal to,
H₂₍₁₎ ₊ ₂
H₂ ₊ ₂
H₄
Hence, this compound is not alkane because it contains only two hydrogen atoms.
C₆H₁₄:
As there are six carbon atoms in this compound hence, the number of hydrogen atoms present for six carbon atoms in alkane must be equal to,
H₂₍₆₎ ₊ ₂
H₁₂ ₊ ₂
H₁₄
Hence, this compound is alkane because it contains fourteen hydrogen atoms.
C₃H₄:
As there are three carbon atoms in this compound hence, the number of hydrogen atoms present for three carbon atoms in alkane must be equal to,
H₂₍₃₎ ₊ ₂
H₆ ₊ ₂
H₈
Hence, this compound is not alkane because it contains only four hydrogen atoms.
