Answer:

Ribosome

Explanation:

Ribosomes are the protein builders of a cell. Most of them are free in the cytosol, but some are bound to the endoplasmic reticulum.

A. Nucleus is wrong. The nucleus stores the cell’s DNA and coordinates its activities.

B. Mitochondrion is wrong. The mitochondria provide energy to the organism through cellular respiration.

D. Lysosome is wrong. Lysosomes are involved in the digestion and removal of wastes from the cell.

It takes 412. KJ/mol to break a carbon-hydrogen single bond. Calculate the maximum wavelength of light for which a carbon-hydrog

olga_2 [115]

Answer:

The maximum wavelength of light for which a carbon-hydrogen single bond could be broken by absorbing a single photon = 290 nm

Explanation:

So to break a single C - H bond require = $\frac{412}{6.023 X (10)^{23} }$

= 6.84 x 10⁻¹⁹ joule

Find the wavelength of a photon we use E = hν

⇒ E = $\frac{hc}{Wavelength}$

Where h = Planck's constant = 6.626 x 10⁻³⁴ J.K⁻¹.Mole⁻¹

c = speed of light = 3 x 10⁸ m/sec

Wavelength = $\frac{6.626 X 10^{-34} X 3 X 10^{8} }{6.84 X10^{-19} }$

= 2.9 x 10⁻⁷ m

= 290 nm

∵ 1 nm = 10⁻⁹ m

You know that chemical a reacts with chemical

Jet001 [13]

The chemical reaction would most likely be written as follows:
A + B = AB
We cannot simply use the usual method of converting grams to moles since we do not have any idea on what are the identities of A and B. The only method we could use is to use the law of conservation of mass where mass inflow in a process should be equal to the mass out in the process. The total inflow of mass would be the mass of A and B and the outflow would be the product AB.

mass of A + mass of B = mass of AB
10.0 g A + 10.0 g B = mass of AB
mass of AB = 20.0 g
