Iodine, I2(s), is more soluble in dichloromethane, CH2Cl2(l), than water because:

Georgia [21]

Answer:

A. the intermolecular forces are similar in both dichloromethane and iodine.

Explanation:

Solubility is determined by the principle , "like dissolves like" .

i.e. , if a compound is polar then it will dissolve in a polar compound only , and

if a compound is non - polar then it will dissolve in a non - polar compound only .

As,

Non polar compounds , have similar interaction , and hence gets dissolved , and similarly ,

polar compounds have similar dipole - dipole interaction , and hence gets dissolved .

From the question ,

Iodine, I₂(s), is more soluble in dichloromethane, CH₂Cl₂(l) , as both are non - polar in nature and hence due to similar interaction , are soluble .

Water is polar in nature and therefore less soluble in Iodine, I₂(s) .

Write a balanced chemical equation, including physical state symbols, for the decomposition of solid sodium azide (NaN3) into so

LenaWriter [7]

Answer:

39g

Explanation:

Details of the solution is shown below. From the information provided regarding the N2 produced, we could calculate the amount of N2 produced and use that to find the mass of sodium azide reacted.
