The amount of heat required to completely melt 347 g of ice is $$\boxed{115.898{\text{kJ}}}$$

Further explanation:

Latent heat  

The heat released or absorbed during the process of conversion physical state of a substance without altering the temperature is known as the latent heat.

When the physical state changes from the solid phase to liquid phase then the amount of heat absorbed in this process to completely convert the solid into liquid without altering the temperature is known as the latent heat fusion.

The formula to calculate heat absorbed from latent heat of fusion is,

$${\text{q}}={\text{m}}{{\text{H}}_{\text{f}}}$$           …… (1)

Here,

q is heat absorbed.

m is mass of substance.

${{\text{H}}_{\text{f}}}$ is latent heat of fusion.

The mass of given ice is 347 g.

The latent heat of fusion of ice is 334 J/g.

Substitute 347 g for m and 334 J/g for ${{\text{H}}_{\text{f}}}$ in equation (1) as follows:

$$\align{{\text{q}}&={\text{m}}{{\text{H}}_{\text{f}}}\cr&=\left( {347{\text{ g}}}\right)\left({334{\text{ J/g}}}\right)\cr&=115898{\text{ J}}\cr}$$

The heat required to completely melt 347 g of ice is 115898 J.

The heat required in kilojoule is as follows:

\begin{aligned}q&=(115898\text{ J})\left(\dfrac{1\text{ kJ}}{1000\text{ J}}\right)\\&=115.898\text{ kJ}\end

In a piece of metal, what holds the atoms together?
alexandr1967 [171]

Answer:

the positive charges of the nuclei and the negative charges of delocalized electrons

Explanation:

The interatomic forces that joins a piece of metal atoms together are the positive charges of the nuclei and the negative charges of delocalized electrons.

This bond type is the metallic bond.

  • The metallic bond is an attraction between the positive nuclei of all the closely packed atoms in the lattice.
  • Also, the electron cloud jointly formed by all the atoms losing their outermost shell electrons.
