(a) Which region of Earth’s crust is not involved in the phosphorus cycle?

Chemistry

Novay_Z [31]1 year ago
3 0

Both abiotic and biotic components of the Earth's system, particularly the biosphere, hydrosphere, and geosphere,  phosphorus. Phosphorus cycle cannot be found in the gaseous state in air, in contrast to the compounds of other matter cycles.

This is due to the fact that phosphorus is typically liquid at standard pressures and temperatures. It mostly cycles through sediments, water, and soil. Phosphorus is primarily present in the environment as very minute dust particles. Phosphorous can also be delivered by water or wind in the form of phosphate (both abiotic). Living plants absorb phosphorus, and these plants can either die and be degraded by other living species or they can die and be consumed by other living organisms.

The strength of a covalent bond depends upon the size of the atoms and the bond order. In general short bonds are strong bonds.1
Oksana_A [137]

Answer:

<u>Bond energy of</u> (A) C≡C > (B) C=C

<u>and, </u>(C) C=N > (D) C-N

Explanation:

Bond energy refers to the amount of energy required to break a bond or the energy released when a bond is formed. Bond energy of a covalent bond suggests the bond strength of the chemical bond and depends on the <u>bond length and bond order of the chemical bond. </u>

<u>The bond energy of a chemical bond increases with the bond order and decreases with the bond length</u>. As, length of a bond decreases with increase in the bond order.

First pair: (A) C≡C (B) C=C

The bond order of C≡C - 3, the bond order of C=C - 2

Since the bond order: C≡C > C=C

Bond length: C≡C < C=C

<u>Therefore, bond energy of (A) C≡C > (B) C=C</u>

Second pair: (C) C=N (D) C-N

The bond order of C=N - 2, the bond order of C-N - 1

Since the bond order: C=N > C-N

Bond length: C=N < C-N

<u>Therefore, bond energy of (C) C=N > (D) C-N</u>

If this decay has a half life of 2.60 years, what mass of 72.5 g of sodium 22 will remain after 15.6 years
Vlad1618 [11]

Sodium-22 remain : 1.13 g

<h3>Further explanation </h3>

The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.  

Usually, radioactive elements have an unstable atomic nucleus.  

General formulas used in decay:  

\large{\boxed{\bold{N_t=N_0(\dfrac{1}{2})^{T/t\frac{1}{2} }}}

T = duration of decay  

t 1/2 = half-life  

N₀ = the number of initial radioactive atoms  

Nt = the number of radioactive atoms left after decaying during T time  

half-life = t 1/2=2.6 years

T=15.6 years

No=72.5 g

\tt Nt=72.5.\dfrac{1}{2}^{15.6/2.6}\\\\Nt=72.5.\dfrac{1}{2}^6\\\\Nt=1.13~g
