According to valence bond theory, which orbitals on N and H overlap in the NH3 molecule? 2p on N overlaps with 2s on H 2s on N o

Alecsey [184]

Answer:

$sp^{3}$ on N overlaps with 1s on H.

Explanation:

Hybridization of central atom generally can be found by finding the hybridization number.Hybridization number is the sum of number of lone pairs and number of sigma bonds.

If hybridization number is 2 then the central atom is sp hybridized.

If it is 3 it is $sp^{2}$ hybridized.

If it is 4 it is $sp^{3}$ hybridized and so on.

Here in $NH_{3}$ molecule there are 3 sigma bonds and one lone pair(see the figure attached).

Hence hybridization number is 4 and hence it is s $p^{3}$ hybridized.

And in case of hydrogen atom the only electron of it resides in the 1s orbital.

Therefore $sp^{3}$ on N overlaps with 1s on H.

How many calories are required to convert 17 g of ice at 0.0Â°C to liquid water at 32.0Â°C? The heat of fusion of water is 80. c

Mazyrski [523]

Answer : The heat required is, 1904 calories.

Explanation :

The process involved in this problem are :

$(1):H_2O(s)(0^oC)\rightarrow H_2O(l)(0^oC)\\\\(2):H_2O(l)(0^oC)\rightarrow H_2O(l)(32.0^oC)$

The expression used will be:

$\Delta H=m\times \Delta H_{fusion}+[m\times c_{p,l}\times (T_{final}-T_{initial})]$

where,

m = mass of ice = 17 g

$c_{p,l}$ = specific heat of liquid water = $1cal/g^oC$

$\Delta H_{fusion}$ = enthalpy change for fusion = $80.0cal/g$

Now put all the given values in the above expression, we get:

$\Delta H=17g\times 80.0cal/g+[17g\times 1cal/g^oC\times (32.0-0)^oC]$

$\Delta H=1904cal$

Therefore, the heat required is, 1904 calories.
