Answer:
f = 1.1041 × 10¹⁵ s⁻¹
λ = 2.72 × 10⁻⁷ m
Explanation:
Given data:
Energy of photon = 7.32 × 10⁻¹⁹ J
Wavelength = ?
Frequency = ?
Solution:
Formula
E = h. f
h = planck's constant = 6.63 × 10⁻³⁴ Kg.m²/s
Now we will put the values in equation
f = E/h
Kg.m²/s² = j
f = 7.32 × 10⁻¹⁹ Kg.m²/s² / 6.63 × 10⁻³⁴ Kg.m²/s
f = 1.1041 × 10¹⁵ s⁻¹
Wavelength of photon.
E = h.c /λ
λ = h. c / E
λ = (6.63 × 10⁻³⁴ Kg.m²/s × 3 × 10⁸ m/s) / 7.32 × 10⁻¹⁹ Kg.m²/s²
λ = 19.89 × 10⁻²⁶ / 7.32 × 10⁻¹⁹ m
λ = 2.72 × 10⁻⁷ m
Answer:
The answer to your question is: letter A
Explanation:
a. Ribonucleotides have a hydroxyl group on the 2 carbons of their sugar sub-unit. This is the main difference between Ribonucleotides and deoxyribonucleotides, the first have hydroxyl group in carbon number two, while the second have a hydrogen.
b. Ribonucleotides contain a phosphate group.
c. Ribonucleotides have a hydrogen atom on the 1 carbon of their sugar sub-unit.
d. Ribonucleotides contain a sugar with five carbon atoms.
Answer:
Assuming that all of the oxygen is used up, 1.53×4111.53×411 or 0.556 moles of C2H3Br3 are required. Because there are only 0.286 moles of C2H3Br3 available, C2H3Br3 is the limiting reagent.
Limiting Reagent What is the limiting reagent if 76.4 grams of C2H3Br3 were reacted with 49.1 grams of O2? C2H3Br3 + 11O2 → 8CO2 + 6H2O + 6Br2 SOLUTION Using Approach 1: A. 76.4g × (1 mol/ 266.72 g) = 0.286 moles C2H3Br3 49.1g × (1 mole/ 32 g) = 1.53 moles O2 B.

Answer:
Explanation:
to put this plainly after putting strong electrolytes in water they dissolve to nothing but ions they give you an example and definition of a strong electrolyte I suggest you read those and see if you come up with what I gave you they also tell you that not all strong electrolytes dissolve as strongly as others that are in the example.
