The rate constant for this zero‑order reaction is 0.0240 M ⋅ s − 1 0.0240 M·s−1 at 300 ∘ C. 300 ∘C. A ⟶ products A⟶products How
maw [93]

Answer: It will take for the concentration of A to decrease from 0.900 M to 0.210 M is 28.75 s

Explanation:

Zero order reaction : A reaction is said to be of zero order if the rate is independent of the concentration of the reactants, that means the rate is directly proportional to the zeroth power of the concentration of the reactants.

Expression for the zero order kinetics:

[A]=-kt+[A]_o

where [A] = concentration left after time t = 0.210 M

[A]_o = initial concentration = 0.900 M

k= rate constant =0.0240Ms^{-1}

t = time for reaction = ?

0.210=-0.0240\times t+0.900

t=28.75s

Thus it will take for the concentration of A to decrease from 0.900 M to 0.210 M is 28.75 s

Which of the following is the abbreviation for a nucleotide containing the nitrogenous base cytosine, a hydrogen at the 2’ carbo
zvonat [6]

Answer:

dCDP

Explanation:

The nucleotide has hydrogen at it second carbon which means that it has deoxy pentose sugar which is written in small d as prefix.

The nitrogenous base is cytosine and it contains 2 phosphate groups which are attached to the 5 carbon of the pentose sugar means it is cytosine diphosphate.

<u>So, the abbrevation of the molecule is : dCDP</u>
