Answer:
<h3>Since we know that carbon atoms tend to make four bonds, each carbon atom will have the number of hydrogen atoms that are required for four bonds. This compound contains 16 hydrogen atoms for a molecular formula of C8H16.</h3>

This hypothesis can be further substantiated by having different concentrations of acid and the same mass of limestone.
<h3>Rate of reaction</h3>
Though the question is incomplete, we must try to answer it the much we can. Recall that a hypothesis is a tentative explanation for an observation which is subject to empirical verification.
We know that the rate of reaction depends on the concentration of the acid. This hypothesis can be further substantiated by having different concentrations of acid and the same mass of limestone.

Answer:
268 nm
Explanation:
First' let's calculate the average bond energy:
(276 + 615)/2 = 445.5 kJ/mol
By Avogadro's number 1 mol = 6.02x10²³ molecule, then the energy necessary to break the amide bond in 1 molecule is:
E = 445.5/6.02x10²³ = 7.4x10⁻²² kJ = 7.4x10⁻¹⁹ J
So, the wavelength of light (λ) can be calculated by:
E= h*c/λ
Where h is the Planck's constant (6.626x10⁻³⁴ J.s), and c is the light speed (3.0x10⁸ m/s).
7.4x10⁻¹⁹ = 6.626x10⁻³⁴ * 3.0x10⁸/λ
λ = 2.68x10⁻⁷ m
λ = 268 nm
