(D) Liquid is being formed.

<u>Explanation:</u>

The enthalpy of fusion of a substance (–Hfus) is the change in its enthalpy when the substance changes its state from a solid to a liquid. It happens when heat is supplied to some quantity of substance which is originally in solid state & it turns into liquid.

<u>Example- melting of ice.</u>

To melt ice energy is required. Approximately, 333 kJ of energy is needed to heat 1 kg ice to convert into liquid.

Answer:

None of the above

Explanation:

By definition heat of fusion (or enthalpy of fusion) is the acceleration of the solid molecules in response to applied energy (heat) turning solid substance into a liquid substance.

makkiz [27]
0.216g of aluminium compound X  react with an excess of water water to produce gas. this gas burn completely  in O2  to form H2O and 108cm^3of CO2 only . the volume of CO2 was measured at room temperature and pressure

0.108 / n  =  24 / 1 
n = 0.0045 mole ( CO2 >>0.0045 mole 
0.216 - 0.0045 = 0.2115
so Al =   0.2115 / 27  =>  0.0078 mole 
C = 0.0045 * 1000 => 4.5    and Al  = 0.0078 * 1000 = 7.8

How many molecules are in 3.6 grams of NaCl?
raketka [301]

Answer:

\boxed{\text{None}}

Explanation:

There are no molecules in NaCl, because it consists only of ions.

However, we can calculate the number of formula units (FU) of NaCl.

Step 1. Calculate the moles of NaCl

\text{No. of moles}=\text{3.6 g NaCl}\times \dfrac{\text{1 mol NaCl}}{\text{63.54 g NaCl}} = \text{0.0567 mol NaCl}

Step 2. Convert moles to formula units

\text{FU} = \text{0.0567 mol NaCl} \times \dfrac{6.022 \times 10^{23}\text{ FU NaCl}}{\text{1 mol NaCl}}\\\\= 3.4 \times 10^{22} \text{ FU NaCl}

There are \boxed{3.4 \times 10^{22} \text{ FU NaCl}} in 3.6 g of NaCl.
