<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:
B, liquid to solid.
Explanation: Since heat is being released, the particles for H2O would clump up. Heat is basically being taken out.
Answer:
The magnesium will burn until consumed entirely. There is much more oxygen available in the atmosphere than needed to consume the magnesium. Thus the magnesium is the limiting reactant because it determines the amount of product formed.
Explanation:
Mg produces less amount of MgO than O2; therefore Mg is the limiting reagent. O2 produces more amount of MgO than Mg; therefore O2 is the excess reagent.
Answer:
Cadmium +p= 48
Titanium p=22
Oxygen p=8
Krypton p=36
So the answer is Cadmium which has #48 protons
