Answer:

52.17%

Explanation:

COCl2.6H20

C=12,O=16,Cl=35.5,H=1

Relative molecular mass of COCl2.6H2O= 12+16+71+6(2+16) = 99 + 108= 207g

Relative molecular mass of 6H2O = 108g

Percentage of water = (108/207 )*100

= 52.17%

No of protons=No of electrons=15

<h3>Mass no:-No of neutrons+No of protons </h3>

$\\ \tt\longmapsto 15+16=31$

Now

It has atomic no 15 hence its Phosphorus(P)

Electronic configuration:-

$\\ \tt\longmapsto 1s^22s^22p^63s^23p^3$ .

Valency=3

Chloride formula:-

$\\ \tt\longmapsto XCl_3$

or.

$\\ \tt\longmapsto PCl_3$

Give the nuclear symbol (isotope symbol) for the isotope of bromine, Br, that contains 46 neutrons per atom.

Doss [256]

Bromine has 35 protons, and in this case 46 neutrons, so 35 + 46 = 81
Therefore, the symbol is (subscript 35)(superscript 81) Br.

Consider the following elementary reaction:

Fudgin [204]

Explanation:

The equation is given as;

N2O(g) ⇄ N2(g) + O(g)

k₁ = Forward reaction

k₋₁ = Reverse Reaction

Equilibrium concentration (K) = k₁ / k₋₁

$K = \frac{[N2O] }{[N2] [ O]}$
