Answer:

Mass = 785.9 g

Explanation:

Given data:

Atoms of gold = 2.4 × 10²⁴ atoms

Mass of gold = ?

Solution:

First of all we will convert the number of atoms into moles.

2.4 × 10²⁴ atoms × 1 mol/ 6.02 × 10²³ atoms

number of moles = 3.99 mol

Now we will determine the mass of gold.

Mass = number of moles × molar mass

Mass =  3.99 mol × 196.97 g/mol

Mass = 785.9 g

A block of ice has little thermal energy. If you place it in a warm room, it melts into warm liquid water, which has much more e
Naily [24]

<u>Answer:</u>

<em>The energy to turn the ice into water:</em>

  • The energy that is required to change the state of ice into a liquid is obtained in the form of heat energy from the ambient temperature of the warm room.
  • Once this heat energy is absorbed, the individual molecules of ice gain kinetic energy and start vibrating faster.
  • Yet, the temperature of the ice remains constant until the ice reaches its melting point because this energy is first utilised to break all the bonds of the lattice structure of the ice.
  • After all the bonds are broken and all of the ice has changed into water, if more heat is provided again, then the temperature of the water will increase.
