Evaporation
Explanation:
From C to D, the phase changes from liquid to gas and it is called evaporation.
Evaporation is a phase change process in which liquid water is converted to gaseous vapor.
During evaporation, the liquid is heated till the particles gain sufficient energy that allows the molecules to escape. The reverse process in which gas is turned to liquid is called condensation.

Answer:
0,31%
Explanation:
For the reaction:
I₂ + 2 S₂O₃²⁻ → 2 I⁻ + S₄O₆²⁻
0,043 L × 0,117 M of sodium tiosulfate = 5,031x10⁻³ moles of S₂O₃²⁻
5,031x10⁻³ moles of S₂O₃²⁻ × 
= <em>2,5156x10⁻³ moles of I₂</em>
These moles of I₂ were produced from:
ClO⁻⁻ + 2 H⁺ + 2 I⁻ → I₂ + Cl⁻ + H2O
2,5156x10⁻³ moles of I₂ ≡ moles of NaClO
2,5156x10⁻³ moles of NaClO ×
=<em> 0,187 g of NaClO</em>
Thus, percentage composition by mass is:
=<em> 0,31%</em>
I hope it helps!
Answer: The law of conservation of mass is reffering to the fact that energy cannot be created or destroyed. So when you speak about atoms not being created or destroyed it is the same thing. Unless you're talking about an atomic bomb where the atoms are split.
