<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.
Answer:
soilds - close together arranged in a regular way
liquids - close together arranged in a random way
gases - far apart arranged in a random way
Explanation:
Examining the given reaction:
Li2O + H2O ........> 2LiOH
we find that, 1 mole of Li2O is required to react with one mole of H2O in order to produce two moles of LiOH.
Therefore, the ration between the required Li2O and H2O is 1:1
Based on this, 2.2 moles of H2O (water) are required to react with 2.2 moles of Li2O
