Why is NH3 soluble in H20 but NCl3 is not?

storchak [24]

NH3 is soluble in water because it has the same amount of intermolecular forces as water. NH3 is a polar molecule and water is a polar molecule so they dissolve each other. NCl3 does not dissolve in water because it is a nonpolar molecule which is different with water. NCl3 is nonpolar due to the difference in electronegativities between 3 atoms of Cl and 1 atom if N2.

What is the volume of a liquid that has a density 3.65g/ml and a mass of 5.61g

Lorico [155]

Answer:

<h2>1.54 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

$volume = \frac{mass}{density} \\$

From the question we have

$volume = \frac{5.61}{3.65} \\ =1.536986...$

We have the final answer as

<h3>1.54 mL</h3>

Hydrolamine ,NH2OH , is a reducing agent found in some film developing solutions. How many hydrogen atoms are in 1.80moles of hy

kolezko [41]

Answer:

number of hydrogen atom in 1.8 mole of NH2OH = $9.8\times 10^{22}$

Explanation:

percentage of hydrogen in NH2OH = mass of hydrogen / mass of whole molecule

= $\frac{3\times 1}{14+3+16}$ \times 100

= 9.09 percentage

therefore number of moles in 1.8 moles of hydroxy amine = $\frac{9.09}{100}\times 1.8$

= .16 moles of hydrogen

number of hydrogen atom = (number of moles )×(avagadro number)

= $9.8\times 10^{22}$ atoms of hydrogen
